Failures in 3D Prints Late in Print

Snapmaker 2.0

I’ve trying to print a basic x/y/z calibration cube to calibrate my printer. What I’m noticing is that for some reason in the Z-direction the print comes out squished most of the time. I’ve had only 1 success out of my first 4 prints (no modification of settings to the print, just leveling the head).

I’m printing on High Quality using the Snapmaker PLA that shipped with the machine. My original thought was that the z-axis was slipping somehow, but I’m not sure what exactly is going on. I’ve checked the z-axis rails and they seem to be pretty tight. Prints are sticking fine to the bed and not gouging or anything. You’ll notice that the squishing is happening past the middle half of the print.

I’ve updated to the latest firmware to eliminate possible firmware related issues.

Perhaps it’s the notorious silicon pad issue? https://support.snapmaker.com/hc/en-us/articles/360051985253-What-should-I-do-if-some-linear-modules-stop-working-randomly-

Do you know if this was a Snapmaker 2 or a Snapmaker 1 issue? I’m seeing this right out of the box with the Snapmaker 2.

As far as I can tell, the silicon pad is only a v2 issue. I haven’t seen any reports of it on the v1. It’s something that usually happens right out of the box on the v2, but some people have reported it working on and off for a while before it consistently fails.

Thanks Sam! I’ll have to take it apart and see what I find.
