Lots and lots of failed prints

Jaydon Runyan May 14, 2017 04:11PM PDT

After about 2 months of use, I am beginning to recognize a pattern with my MOD-t. Any time I try to print anything that takes longer than about 4 hours, or is taller than about .75 inches, the print suddenly develops an offset. It will print the first 100 layers or so, and after that it seems that there is a shift in the print bed or the calibration fails, because it keeps printing the part of the .stl/.obj that it should be printing, but it is shifted from the layers beneath it. I cannot find a solution to the problem but I am very tired of wasting time and plastic because it will not print correctly. If anyone has had this same issue, or knows what I can do to fix it, please please please let me know.

Hi Jaydon, thanks for letting us know. We are seeing an issue currently where prints utilizing the full axis in one or more directions are seeing a slight stutter when going to the four far corners along the pinion rods, causing print shifting, and a possible catch during the calibration. This is an unfortunate hardware issue we’ve been grappling with for quite some time. For that we apologize, as you should totally be able to use the full build envelope of 6″ × 4″ × 5″ with no issues.

The good news is that we’ve created an attachment, called MOD- Skis, that have helped many of our customers resolve their print-shifting issues. In order to get the Gcode to print the file and full instructions on installing it, please contact our support team via email at, let them know you want the file for the MOD-Skis modification, and they’ll send it to you as soon as possible!
