Summary

New Matter MOD-t 3D printer is a nice cheap printer. It has an unique cold printing bed system that makes easy to detach printed parts. But the design of the upper part makes sometimes the printing process problematic as it can happen (quite often) that the head push or pull a little border of a previous layer (for example when leaving a blob). This makes the upper part of the printing bed to move and the layers alignment is gone. Sometimes this means ugly prints, sometimes (in particular with mechanical parts or interlocking pieces) this means non working printed objects.
So I made those clips, after MANY iterations to get the right compromise they are the perfect solution to 100% solve the bed slippage!
Just put the clips in the upper holes and voilà! Your bed is stiff and stay perfectly in position, even in worst test cases.
From now on I'm never printing without them! I never had layer misalignment again :)

Here you can see how to use them: https://youtu.be/sYksQoI75H0

You can download the .stl and slice it on your own or you can download the .gcode file, ready to be printed with the MOD-t printer (don't try it with other printers!!!)

MOD-t optimizations

Special warning, please read!

If you use my latest (updated 30 June 2016) Cura or Slic3r settings (available here: http://www.thingiverse.com/thing:1535333 ) you'll have no problem using my Clips.
If not it's advised to update your start gcode in your slicer software with the one provided in the start_gcode.txt file. This will slightly change the post calibration priming on the right so that it will not touch the right clip.
I've also been in contact with New Matter engineers to ensure that the clips will not interfere with the calibration procedure and they say that they aren't interfering at all.
With firmware 0.13 I've noticed that sometimes, during calibration, the bed can slip/grind on the pinions rod but this is "normal" (they say). To reduce the probability that this happens position the bed in the middle on the Y axis and slightly in the left in the X axis before to start the print operation.

With the 0.14 FW, I had to use an exacto knife to round out the corner to avoid collision with the starting calibration "nose-wipe". After that it continued to work wonderfully. Thanks again for supplying these to the community.

Thank you for the feedback! So I know that clips are printing fine even with latest firmware :)
I had to do the same, that's why I've added the section "MOD-t optimization" in the lower part of the page, did you miss it or I had not added it yet when you printed the clips?

I cant wait to try this! Any word on how they are working today with the current firmware?

I'm making every single print with these clips! I'm on 0 13 as with 0.14 the bed never end the calibration phase but that should not be related to clips. I don't know how fit will they be printing them with latest FW as extrusion path algorithm changed a lot. I'll make a pai with 0.13 and let you know.

Just a heads up with the new 0.12 update the new homing procedure seems to knock off the plate when using this clips

I didn't receive the 0.12 firmware yet but I've read in the MOD-t google group that the new procedure knock the plate and try to go further grinding the pinions. Have you tried with and without the clips?

Yeah it used to home left right up down but now it homes in an arc touching the top left and top right of the build plate. It works fine without the clips and it prints in half the time than it previously took. I slowed down my cura settings quite a fair bit though and the plate does not seem to slip anymore.

Ok, I've received the new 0.12 firmware too. I did two print without calibration problems, no grinding, no problem using clips. I've read on the google group that the calibration is going more smoothly if the carriage starts from the center. Could it be that? I would be worried to not use clips on long prints!!! :)

On 0.12 I just had the hot end stick to one of the clips! I have no idea why though, wasn't printing even near that area. Calibration has been smooth for me

That's strange... It's true that clips occupy a small part of the theorical print area (if configured with width 155) but you have to print an object with a HUGE base that occupy 100% of the printing bed to touch the clips. That's very improbable. Maybe it was during the calibration process that something happened... I had contact with New Matter engineer about this and he said that to achieve better results in 0.12 calibration, before to launch a print, you have to position the printing bed mid in Y direction (half way from top to bottom) and someway to the left in the X direction.
I think there's something weird that has to be corrected in the new calibration. I had pinion rods hopping and an infinite loop that I've filmed and I'll send it to engineers to improve that.

Yeah, I saw that in the google group after that print. I had it in the bottom right corner (as per earlier instructions from a NM rep)
I'll try them again. I really had a hard time getting them installed though, seemed way to small, I touched them up with an exacto knife to get them to fit.

BTW, why not make some for the other holes, for symmetry ;)

This is the single greatest thing I've printed so far! THANK YOU! I've had my last 3 prints shift on me. Nice work!

And thank you for showing me your appreciation! I'm happy to have helped people that had layer shifting like me, that was not cool... :)

Are you using the cura config from new matter or you own config ? Your settings seem WAAAAY better.

Frankly I don't remember as I thinkered so much with them... I mixed up the official settings with these https://github.com/ajfoul/MOD-t/tree/master/Cura and added some post gcode to cool down the head (I see that ajfoul did it too now). However I've seen that the quality depends much on the filament you use and the settings for that specific filament. For example I have a blue BQ filament that needs lower temp or less extrusion to be ok. I did many trials and errors and I continue to do that at every print, to be honest...
Try to print this: http://www.thingiverse.com/thing:1420859 and post your result on the "made" section, so we can compare :)

I have printed it using the cura settings provided by new matter at http://support.newmatter.com/customer/en/portal/articles/2339345-new-matter-blog-using-cura-with-the-mod-t. Are you able to print 3DBenchy ? Last few times I tried I did not have your bed clips yet and the plate came off 3 times.

HS Printer test - ver 3

Hi and thank you for sharing your experience! I think you exchanged the correct link with the one of your make of my printer test. I never tried to print 3dbenchy. I'll do it and I'll share my result in the next few days :)

Thank you so much, this eliminated my issue of offset printing completely!

I'm so happy to know that these clips are useful to people! In fact they where so useful to me that I couldn't avoid sharing them :)

Looks like an interesting solution!

Thank you, please try it and let me know how it's working for you! :)
