76 | <p>When 3D Printing moves into public beta, you're going to want to get the word out. And fast! One of the best ways to advertise ourselves across the entire Stack Exchange network is through community ads. </p>
<h3>So what are these "Community Ads?"</h3>
<p>Graduated sites allow the community to advertise relevant products or services within the site, using a system where the community chooses what to advertise. You can find these posts on per-site metas. Hint: these posts have the <a href="/questions/tagged/community-ads" class="post-tag moderator-tag" title="show questions tagged 'community-ads'" rel="tag">community-ads</a> tag!</p>
<h3>Cool! What should the ad be like?</h3>
<p>There's a few requirements for these ads. Most notably,</p>
<ul>
<li>They must be 300px wide by 250px tall, or double for "retina" displays</li>
<li>There's a limit on file size of 150 kB.</li>
<li>The image must be hosted on i.stack.imgur (the Stack Exchange image hosting service).</li>
<li>Ads must be GIF or PNG (no animated GIFs).</li>
</ul>
<h3>What else should I know?</h3>
<p>To facilitate easy posting to other sites, make sure that the embedded image is of the following format:</p>

<p>You can also include a message as a part of your answer with your own thoughts: why you chose some of the elements, and what sites the ads could potentially be posted to. Don't forget to critique each other as well!</p>

151 | <p>Are there any official naming conventions for tag names on Stack Exchange? And if not, how should tags be named?</p>
<p>From what I understand, one typically adds a <em>dash</em> (-) where you normally would leave a <em>space</em>, but how about tags that derive from words that are <em><a href="https://3dprinting.meta.stackexchange.com/questions/150/tag-for-mattercontrol-app">CamelCased</a></em>, or somehow <em><a href="https://3dprinting.stackexchange.com/questions/tagged/postproduction">Prefixed</a></em>?</p>

Post-production | postproduction | post-production
Post-processing | post-processing | postprocessing

264 | <p>I can't find an answer to this question on the "mother" meta website; hope this is not related to my choice of words in the search box. </p>
<p>The statistics of the <a href="https://3dprinting.stackexchange.com/">3D Printing</a> on <a href="http://area51.stackexchange.com/proposals/82438/3d-printing">Area51</a> show that only few items (questions and visits per day) are not up to par and need work. Do those need to reach a level of let's say "okay" before the site can loose the Beta stage?</p>
<p>I'm interested to know what would be the requirements to get out of the Beta stage.</p>
<hr>
<p>Update September 5, 2019:</p>
<p>It appears that the <em>"visits per day"</em> is <em>"excellent"</em> with close to three thousand visits. The "questions per day" still lack behind with a 3.0 value (<em>"needs work"</em>) while more than 5 is considered "healthy". All further stats seem to be <em>"okay"</em> or <em>"excellent"</em>.</p>

answer</a>, to <a href=\"https://robotics.meta.stackexchange.com/questions/1354/graduation-of-this-community\">“Graduation” of this Community</a>:</p>\n<ol>\n<li>A number of 10k+ users ( <em>n</em> > 3 ) are required to access mod tools</li>\n<li>A number of 3k+ users ( <em>n</em> > 10 ) are required to be able to fully vote</li>\n</ol>\n<h3>The final hurdle</h3>\n<p>The main sticking point, according to this meta post on Ethereum, <a href=\"https://ethereum.meta.stackexchange.com/questions/474/congratulations-ethereum-is-graduating\">Congratulations! Ethereum is graduating!</a>, is 10 questions per day, which we are a long way from, and seems to be the last remaining issue.

If you want people to show up and do things, you (and everyone else) needs to vote. Up, down, sideways ... doesn't matter. They all help drive people to <em>do things</em> in every Stack.</p>\n\n<p>Looking at the above link, you can see one of the things which is important to graduation is having the right user base. You have to have people who have the ability to do things which only those who have met the point level can do. As it stands the highest ranked person by point total is <a href=\"https://3dprinting.stackexchange.com/users/26/tom-van-der-zanden\">Tom van der Zanden</a>. He hasn't (as of this writing) broached 10k points. There are two users who have more than 5k points, and another five who are over 2500. How do you improve this scenario? You guessed it, by voting. </p>\n\n<p>I realize with sub two questions per day (QPD), there's not a lot to vote on. That can be overcome as well. Those of you who have had issues or have met challenges have knowledge. Write down those challenges you've faced in a question. Then, either write an answer for them, or let someone else figure them out. Either way, you are creating opportunity for the site to expand. That opportunity will be giving someone a chance to vote and/or answer the question. Plus, you are doing what SE wants done in the first place: <em>bringing and recording knowledge</em>. It's a win-win.</p>\n\n<p>There's a ton of other things which can be done to get 3D Printing graduated. I'm sure we'll get there sooner or later. I hope I can help in some small way. I'm not the bastion of all knowledge to get a site graduated, that's for sure, but having gone through it with Mechanics gives me some insight.</p>\n\n<p>Here's to the future and what it will bring.</p>\n"

] | I can't find an answer to this question on the "mother" meta website; hope this is not related to my choice of words in the search box.
The statistics of the [3D Printing](https://3dprinting.stackexchange.com/) on [Area51](http://area51.stackexchange.com/proposals/82438/3d-printing) show that only few items (questions and visits per day) are not up to par and need work. Do those need to reach a level of let's say "okay" before the site can loose the Beta stage?
I'm interested to know what would be the requirements to get out of the Beta stage.

Update September 5, 2019:
It appears that the *"visits per day"* is *"excellent"* with close to three thousand visits. The "questions per day" still lack behind with a 3.0 value (*"needs work"*) while more than 5 is considered "healthy". All further stats seem to be *"okay"* or *"excellent"*. | This post, [3D Printing SE Beta Status](https://3dprinting.meta.stackexchange.com/questions/197/3d-printing-se-beta-status), by tbm0115 highlights the *three main* sticking points (IMHO clearer than the Area 51 page):
* Questions per day
* Users vs Reputation
* Visits per day
Once those reach the required levels then that should be it. So, there is quite a way to go...
The stats can be seen here, [3D Printing Area51 site](http://area51.stackexchange.com/proposals/82438/3d-printing):

\* This change in the number of users with *X* reputation is, in part, due to the move from +5 to +10 reputation for upvoted questions on [13 Nov 2019](https://stackoverflow.blog/2019/11/13/were-rewarding-the-question-askers/) (see also [Upvotes on questions will now be worth the same as upvotes on answers](https://meta.stackoverflow.com/q/391250/4424636)).

### Additional points of note
The stats above aren't really the be all to end all... there are a few other considerations that I came across here, [in this answer](https://robotics.meta.stackexchange.com/questions/1354/graduation-of-this-community/1355#1355), to [“Graduation” of this Community](https://robotics.meta.stackexchange.com/questions/1354/graduation-of-this-community):
1. A number of 10k+ users ( *n* > 3 ) are required to access mod tools
2. A number of 3k+ users ( *n* > 10 ) are required to be able to fully vote
### The final hurdle
The main sticking point, according to this meta post on Ethereum, [Congratulations! Ethereum is graduating!](https://ethereum.meta.stackexchange.com/questions/474/congratulations-ethereum-is-graduating), is 10 questions per day, which we are a long way from, and seems to be the last remaining issue. A link ([Graduation, site closure, and a clearer outlook on the health of SE sites](https://meta.stackexchange.com/questions/257614/graduation-site-closure-and-a-clearer-outlook-on-the-health-of-se-sites)) from the Ethereum meta post to Meta.SE states:
>
> When a site starts to consistently receive 10 questions/day, we’ll consider it for graduation.
>
>
>
### No graduation, but losing the Beta label...
Apart from graduation, SE management has recognised that small sites (with an active community) struggle to reach the 10 questions/day consistently. For sites that have been waiting to get out of Beta by graduation for 7-8 years, SE has decided to drop the Beta label. Please see [Congratulations to our 29 oldest beta sites - They're now no longer beta!](https://meta.stackexchange.com/questions/331708/congratulations-to-our-29-oldest-beta-sites-theyre-now-no-longer-beta?cb=1).

There is a complete write-up on it over at <a href=\"https://stackapps.com/q/2116/54833\">StackApps</a>, which is SE's site for just this sort of thing. </p>\n\n<p>One of the great things about it is it's completely customizable. I've found since I've been sneaking around here on 3D Printing, it automagically sets the \"welcome\" note to the current site, as well as if there are custom comments you've added on another site won't show up here. That's pretty kewl in my book. One of the things you could do is to create custom comments within the add-on copied from the other great Answers in this Meta post. </p>\n"

<li>Sensor Voltage $ U_sens = U_L$</li>
<li>Temperature control (Hotend/Bed/Cooling fans) $ U_T = U_S$</li>

When we discuss [movement paths](https://3dprinting.stackexchange.com/a/5155/8884), we also come into need for 3D geometry which can be simplified by using non-carthesian coordinates or functions - which in turn need manual typing of greek letters or proper formulas to be displayed well.
Up to now I have been typing LaTeX formulas in online converters and copy paste the link to the image generated formula. This is quite labor intensive, especially since the SE does support built in MathJax.
A recent [answer](https://3dprinting.stackexchange.com/a/6540/5740) showed LaTeX/MathJax code in the answer, but that did not render into an actual formula image as it is not enabled.

Why can't we enter formulas directly in posts? | $$\text{3D Printing Stack Exchange} \subset \text{Stack Exchange sites that use MathJax}$$
There are [~17 posts](http://data.stackexchange.com/3dprinting/query/879802/mathjax-inline) that could use an edit. Most of those are prices that have been converted into MathJax. You can fix that by escaping the dollar sign:

I'll work on those edits myself, but I'd love to get some help. |

However, it looks as though you can just go to <code>Print Settings -> Speed -> (Modifiers) First Layer Speed</code>. Here you'll have the option to set the speed in <code>mm/s or %</code>. If you're having issues with the first layer (or two) not adhering very well to a raft, try reducing the distance between the part and the raft. Mine looks to be a default of 0.2mm. This can be adjusted from <code>Print Settings -> Support Material -> (Options for support material and raft) Contact Z distance</code>.</p>\n\n<p>Please note that the closer the part is to the raft, the more likely the part is to sticking to the raft once it cools. So, I would recommend being close by as the part finished so you can quickly remove the raft before it cools with the part. It become especially more difficult with PLA because it becomes hardened during the print process, therefore resulting in a more catastrophic material failure if any part of the object is broken (such as a raft).</p>\n\n<p>I'll also note that I primarily use MakerWare for my machine and v3.8 has made it much easier to apply these types of settings. It's similar to Slic3r's interface and no longer in a JSON file that pops up. Through the MakerWare interface, you can navigate to <code>Settings -> Custom -> Extrusion Speeds -> First Layer</code> to adjust the print speed. You'll also notice that there is a separate option for <code>First Layer Raft</code> that ensures that the two values are separate in the post-processer. I believe it still may be possible to use MakerWare for a non-MakerBot machine, just export the file to GCode and you should be able to load it directly into your machine via SD card or possibly even Slic3r (it might change some of the code though).</p>\n"

] | When you add a raft in Slic3r, the first layer of the raft prints at the first layer speed. After the raft is finished, the first layer of the print prints at the standard speed. How can I make the first layer of the actual print slow down to the first layer speed? | This is still work in progress, and here is what I have so far, but first:
**A useful alternative for similar problems:**
A problem very similar to this would be to use different settings for different parts of a model in Slic3r. For most settings, this can be achieved through [modifier meshes](http://slic3r.org/blog/modifier-meshes).
Post processing scripts:
========================
As far as I know, Slic3r does not give you the option of setting the speed of the first layer after a raft directly, but they do allow you to run [post processing scripts](http://manual.slic3r.org/advanced/post-processing); that is, to automatically run a set of operations - programmed by you - on the g-code output.
Although far from trivial, you can in theory make a program that runs through the output g-code, adjusts the settings to your preference, and then saves it again at the target destination.
### Tuning overall printer speed through g-code:
As it turns out, there is a [simple g-code command](http://reprap.org/wiki/G-code#M220:_Set_speed_factor_override_percentage) that sets the overall speed of your printer's operation:
```
M220 S[some number] ; see the link above for compatible firmware
```
A [newsletter](http://reprapworld.com/newletters/newsletter_4_201438.pdf) from Reprapwold explains that:
>
> For example M220 S50 will reduce the speed to 50%
> of the original sliced G-code. If you want to hurry your print to the finish in time
> for dinner, use M220 S200, to print twice as fast (200%)
>
>
>
In other words, just like some printers allow you the change speed mid-print, you can use the M220 command to override the current speed used, either through a user interface such as PrintRun, or by fiddling with the original g-code itself.
### Manipulating the g-code output to adjust speed settings:
The easiest way to achieve our goal would be to manually manipulate the output g-code file through a text editor, and insert our M220 command in appropriate places:
* Set M220 S50 just before the first *perimeter* layer (after the raft's *interface layer*), to slow down the first layer of the actual model.
* Set M220 S100 sometime after the first perimeter layer, to resume the normal speed settings.
In order to do this, though, we need to be able to distinguish these two points in the g-code output.
### Distinguishing insertion points:
Slic3r offers a setting under `Print Settings -> Output options -> Verbose G-code` that - when enabled - inserts written comments all throughout the g-code files generated.
If one inspects a g-code file outputted for a model with raft, one will find the comment:
```
; move to first perimeter point <- lets call this A
```
and
```
; move to next layer (x) <- lets call this B
```
littered several places throughout the gcode.
It is under my *impression* that the *first* occurrence of comment **A** happens right after the raft is finished, and before the actual model is being printed, while the first occurrence of comment **B** succeeding comment **A** can be used to set the speed back to normal.
It should be noted, however, that **the comments in the output g-code does not seem fully consistent**, and I would therefore not recommend anyone to automate this logic into a script without possibly finding other, more reliable breakpoints, and thoroughly verify these through several different models.
I have not looked into the details of writing an automatic script for this task as of yet. |

Will the material a bed is made out of affect how long it takes a part to cool? | **What bed material cools faster?**
I found an [extensive list](http://www.engineeringtoolbox.com/thermal-conductivity-d_429.html) which relates various materials to their *thermal conductivity*, k [W/mK]; the lower thermal conductivity, the better the material insulates, and the slower the print bed will resist changes in temperature - both heating up, and cooling down.
Here are the thermal conductivity for some common materials for 3d printer beds:
```
Aluminum 205
Glass 1.05
Acrylic 0.2
Air 0.024 (for reference)
```
There is also the matter of thermal capacity, but I will not go into that right now (need to do some research myself first!).
**Will bed material affect cooling time?**
Bed material, I believe, is not necessarily related to print cooldown time: it depends on the situation, such as whether we are discussing cooldown during or after printing, and if the bed is heated or not.
1. If you are *not* using a heated bed, I believe the bed material doesn't matter at all.
2. With a heated bed *while printing*, only the first dozen layers or so are probably affected by the rising heat sufficiently that it affects the printing process.
3. With a heated bed *after printing*, the thermal characteristics of the bed will determine how quickly the print cools (and thus can be removed).
Also remember that other physical properties, such as flatness (both cold and during heating) of the bed material is vital for successful prints, and that not all materials can tolerate heating equally well! |

You can accomplish that just about any way you like, so long as you pair up the wires correctly from one motor to the other.</p>\n\n<p>I'm assuming both \"Z\" motors are the same type and have the same color-coding for their wires. If not, you'll need to figure out the correspondences first (you may want to post another question if you need a hand with that, since it's pretty specific and generally useful).</p>\n\n<p>Many control boards have \"headers\" sticking up, with 4 bare pins for each motor.

The first thing is to check continuity: find 2 pairs of wires, which are the ends of two separate coils.

I find this unclear because it could just as well have been numbers for the coils, and letters for the ends (if you wire it that way it won't work). So be sure you have continuity (maybe 15 ohms or so) between the wires you connect to 2B and 2A, and between the wires you connect to 1A and 1B.</p>\n\n<p>The <em>really good thing</em> about this pin order is that if a motor is running backwards all you have to do is power off and then turn the plug around.

] | There is a little circuit board, or breadboard or something [in the diagram of the wiring for the i3](http://reprap.org/wiki/Prusa_i3_Rework_Electronics_and_wiring#Wiring).
And it's mentioned that the z-axis motors need to be [wired in parallel](http://reprap.org/wiki/Prusa_i3_Rework_Electronics_and_wiring#Motors_wiring) but beyond that they don't give you much detail about parts or how the wires go in.
Can someone provide me with some more detail on this? | In the diagram, they do show the wires connecting together, which is right. You can accomplish that just about any way you like, so long as you pair up the wires correctly from one motor to the other.
I'm assuming both "Z" motors are the same type and have the same color-coding for their wires. If not, you'll need to figure out the correspondences first (you may want to post another question if you need a hand with that, since it's pretty specific and generally useful).
Many control boards have "headers" sticking up, with 4 bare pins for each motor. Connectors that plug right onto those are readily available, such as at <https://www.sparkfun.com/products/10364>.
Some ways you can wire the motors in parallel:
* Some control boards, like my RAMPS 1.4, provide 2 sets of header pins next to the Z stepper driver board. In that case, just put a connector on each motor (if they're not there already), and plug them in next to each other.
* If there's just one set of header pins (or one Z-motor socket of some other kind) on your controller, make a "Y-cord" by soldering the wires from one connector (that plugs to the controller) to *2* 4 pin connectors, one to mate with each motor.
* Or you can skip the 2 extra connectors entirely, and just solder the motor wires to the wires from the connector: 2 reds to red, 2 blacks to black, or whatever.
* If your controller just has empty holes, either solder in header pins and do as above (preferred, IMHO), or wire directly into the holes, splicing the 2 sets of motor wires if there's only one set of holes.
Motor and connector wires are wildly inconsistent, so make sure you get them sorted out right if they aren't already. The first thing is to check continuity: find 2 pairs of wires, which are the ends of two separate coils. If your motors have more than 4 wires it's trickier.
With RAMPS (see handy diagram [RAMPS 1.4 RepRap Arduino Mega Pololu shield](http://makerdev.com/blog/wp-content/uploads/2014/02/ramps_fanboard_annotations.jpg)),
[](https://i.stack.imgur.com/A6lsT.jpg "RAMPS 1.4 RepRap Arduino Mega Pololu shield")
the 4 pins are commonly labelled (starting from the one nearest the power-supply end of the RAMPS board):
```
2B 2A 1A 1B
```
It means coil 1 and coil 2, each of which has ends A and B. I find this unclear because it could just as well have been numbers for the coils, and letters for the ends (if you wire it that way it won't work). So be sure you have continuity (maybe 15 ohms or so) between the wires you connect to 2B and 2A, and between the wires you connect to 1A and 1B.
The *really good thing* about this pin order is that if a motor is running backwards all you have to do is power off and then turn the plug around. That's one reason I think it's important to keep connectors in there, rather than soldering directly. |

] | I'm using Cura as my slicing/printing software and I just started using the BuildTak printing surface.
The BuildTak is damaged by pushing a hot nozzle into it and my printer's (Robo3D R1+) autoleveling feature works by pushing the nozzle into the build surface.
Is there a way to configure Cura so that it runs the Z probe first, then heat up the nozzle?
My first sheet of BuildTak already has 10 small holes in it (at the homing position and at the 9 leveling touch points) | In Cura (and Slic3r), you can 100% customize what the printer does before printing your actual model through custom **start/end g-code**.
If you navigate to the `Start/End-GCode tab in Cura`, then select `start.gcode`, you can see what operations are run before each print begins. Lines prefixed with `;` are comments, and does not affect the printing in any way.
Basically, we want to manually tell the printer to do the auto leveling *before* heating up the nozzle by editing the g-code in `start.gcode`.
### G-Code generated with the default start.gcode:
If you try to slice some model with the default code found in `start.gcode`, you will get something like the following (depending on your printer):
```
; CURA AUTOMATICALLY INSERTS THESE TEMPERATURE CODES
M190 S70.000000 ; Set bed temperature to 70 degrees
M109 S210.000000 ; Set nozzle temperature to 210 degrees
; THESE ARE THE CODES FROM START.GCODE (for a ROBO 3D R1)
G28 ;move printer to endstops (the home position)
G92 E0 ;zero the extruded filament length
M565 Z-1 ;set z-probe offset
G1 Z5 F5000 ;move the printer 5mm above the bed
G29 ;run auto-leveling
; THE ACTUAL MODEL BEGINS HERE
;Layer count: 168
;LAYER:0
.
.
```
### Analyzing the g-code output
At the top of this code snippet, we can see that Cura automatically inserts g-code for heating up the bed and nozzle to their respective temperatures with the [M190](http://reprap.org/wiki/G-code#M190:_Wait_for_bed_temperature_to_reach_target_temp) and [M109](http://reprap.org/wiki/G-code#M109:_Set_Extruder_Temperature_and_Wait) g-codes. This means the printer always will heat up the nozzle before reading the `start.gcode`s that we set. However, if we manually override [M109](http://reprap.org/wiki/G-code#M109:_Set_Extruder_Temperature_and_Wait) code in `start.gcode`, the [M109](http://reprap.org/wiki/G-code#M109:_Set_Extruder_Temperature_and_Wait) at the top will automagically disappear from the generated g-code output! (Thanks, @TomvanderZanden!)
We could therefore use the auto-leveling command [G29](http://reprap.org/wiki/G-code#G29:_Detailed_Z-Probe) before manually setting the nozzle temperature with [M109](http://reprap.org/wiki/G-code#M109:_Set_Extruder_Temperature_and_Wait); specifically, we want to add `M109 S{print_temperature}`, which reads the `Basic -> Print Temperature`-setting in Cura, and replace `{print_temperature}` with it automatically.
### Manipulating start.gcode:
In order to postpone heating the hotend till after probing, `start.gcode` could be something like:
```
G28 ;move printer to endstops (the home position)
G92 E0 ;zero the extruded filament length
M565 Z-1 ;set z-probe offset <----- ( YOU HAVE TO ADJUST THIS, READ BELOW)
G1 Z5 F5000 ;move the printer 5mm above the bed
G29 ;run auto-leveling
M109 S{print_temperature} ;set nozzle temperature, and wait for it heat up
```
And that's about it! You can then use these codes in your `start.gcode`. However, you probably will have to recalibrate your z-prove offset.
### Adjust z-probe offset:
Normally, auto-leveling is done with the nozzle heated for a reason: when the nozzle is warm, it expands slightly, moving closer to the bed. You might therefore have to adjust your Z-probe offset with the [M565](http://reprap.org/wiki/G-code#M565:_Set_Z_probe_offset) command (as demonstrated in the snippet) to account for the increase in nozzle length when warm.
### Remember:
Remember that when editing g-code in this manner, you will take full control of how the printer operates. You could therefore very well do something unintended, so keep the power switch close! |
456 | <p>I am wondering how people that use standalone 3D printers (printers that have the ability to print autonomously from SD Card) feed in filament, prime the printhead and/or change filaments without a laptop ?</p>
<p>Do the printers have a menu to arrange all these tasks ?
I often only see the options to preheat the head to a certain temperature, but not to load/unload filament, extrude a small amount etc.</p>
<p>I understand this differs from printer to printer, but still am wondering about this.</p>

More optimization, fewer things that need to be configured by the end-user. But in exchange, you're limited in what kind of hardware Sailfish will support. It's a tradeoff.</p>\n\n<p>In comparison, LCD support was more strapped onto RepRaps as an option rather than the core interface element.

] | I am wondering how people that use standalone 3D printers (printers that have the ability to print autonomously from SD Card) feed in filament, prime the printhead and/or change filaments without a laptop ?
Do the printers have a menu to arrange all these tasks ?
I often only see the options to preheat the head to a certain temperature, but not to load/unload filament, extrude a small amount etc.
I understand this differs from printer to printer, but still am wondering about this. | My printer (IdeaWerk 150) is very basic and doesn't have any options for this from the screen.
I wrote a really simple GCODE file that brings the nozzle up to temperature, then runs the extruder for a few seconds, then waits, then extrudes for a bit again. I think it does this 3 or 4 times then stops. I can put the file (when converted to .x3g!) onto an SD card and run it whenever I need it.
I have a similar file that allows me to level the bed without a computer by just moving the nozzle around to a few key points on the bed and pausing for a few seconds.
I used a GCODE file generated by my slicer in verbose mode to get started, along with a [list of codes](http://softsolder.com/2013/03/14/g-code-and-m-code-grand-master-list/)
I don't have these files to hand at the moment, but this is my `start.gcode`:
```
(**** beginning of start.txt ****)
(This file is for a WeisTek IdeaWerk 150)
(**** begin initilization commands ****)
G21 (Metric FTW)
G90 (Absolute Positioning)
M18 (This disables the stepper motors.)
G92 X0 Y0 Z0 A0 B0 (Declare the current position to be 0,0,0,0,0)
(**** end initilization commands ****)
(**** begin homing ****)
G161 Y X F2500
G92 X0 Y0 Z0 A0 B0
G1 X5.0 Y5.0 Z-5.0 F450
G162 Z F450
G161 Y X F2500 (Home X axis maximum, go until reaching the end stop.)
G92 Z142.4 ( ** Set Bed Height ** )
G92 X-75 Y-75 (set zero for X and Y)
(**** end homing ****)
M108 R8.0 (Extruder speed = max)
M6 T0 (wait for toolhead parts, nozzle, HBP, etc., to reach temperature)
G1 Z10 F500 (Bring bed up)
M101 (Turn on Extruder)
G04 P8000 (Wait for 8 seconds for flow)
(**** end of start.txt ****)
```
If I feed *just* this file into my printer, it will heat up the nozzle, bring the bed up to about 10cm below printing height and once the nozzle is at temperature, it turns on the extruder for 8 seconds.
Your printer will likely be different to mine - there are a few different flavours of GCODE and you will likely have different XYZ positions, so take a look at some GCODE generated by your own slicer and identify the different parts. The principle is the same. |

However, according to [this](https://github.com/daid/Cura/issues/385) a discussion, that is now deleted from GitHub, about the Cura slicing engine:
The **E** values are in *absolute mode*, so perhaps the firmware is attempting to move the stepper motor to the absolute position (which is almost 50% through your print). This may lead to clogging or skipping depending on how hot your extruder is at that point.
As a last resort, you can perform a Boolean subtract on your model of the section that's already printed and re-slice the model to print the remaining bit. Then glue, or ABS weld, the remaining piece to the main print. I've done this in the past, it's not super glamorous, but it gets the job done if the part doesn't require a lot of structural integrity.

You may be able to <em>print</em> the design using SLA, but handling would be very difficult before post-processing as the part is very brittle post-print until a heat treat or curing process is done to chemically solidify. The post-process of the SLA could determine how strong the part is (ie. stainless steel powder, infused with bronze in a heat treat process would be good for such a part).</p>\n\n<p>While SLS may be the best method for 3D printing this type of design, for that size part (30x30x10cm) you're looking at an expensive print regardless of whether or not you print it yourself.</p>\n\n<p>Instead, I would highly recommend finding (or designing your own) a joint connector that would allow you to join wood/plastic dowels in the tetrahedral honeycomb shape. Not only will this be cheaper for you in the long run (easier to replace a few broken segments than an entire 3D printed model), but it could provide more structural strength for something that could potentially get banged around, like a tricopter.</p>\n\n<p>For example, <a href=\"http://www.thingiverse.com/thing:176263\" rel=\"nofollow noreferrer\">this model</a> on Thingiverse (not my model) shows an example of how you can utilize 3D printing complex or custom joints that allow you to connect dowels in the shape you're looking for.

<li>Marlin source code </li>
</ul>
<p>My main task is to convert my 3D printer into a chocolate printer.

<pre><code>// Travel limits after homing
#define X_MAX_POS 200

#define Y_MAX_POS 190 <<<< (tested with 190 and 210)

<pre><code>// The position of the homing switches
