I know you've used PETG a lot in the past without problem, but I'd try slowing down. The extrusion rate may be sucking too much heat out of the nozzle, causing it to jam up. They may have changed the filament formula a bit, or this batch is wonky.

From what I've read, "Linear Advance" might help, but it appears to require installing new firmware in the controller board. I looked into this, and decided it was going to be too complicated for me to bother with at the moment.

You say you have an M2, but not what rev. Somewhere (possibly just the E version), they moved the limit switch to the bottom, and reversed where "zero" is for Z. It sounds like you have an older machine with the limit switch at the top. I'm not sure where or how to modify this, but if you can compar...

I have a 2 year old M2E that has developed a squeal when the Z-axis moves rapidly over a significant distance at the start or end of a print. All the gory details are here: http://forum.makergear.com/viewtopic.php?f=7&t=5453&p=38969#p38969 It appears I will probably need to replace the plastic leads...

I have a 2 year old M2E, with the black motor mounted on the lower base, and what I believe is a plastic nut on the bed spider. Just in the last few days, at the end or start of the print when the bed is making a large fast vertical movement, I get a brief screeching noise like the OP on this thread...

I just switched from red eSun PLA+ filament to a new spool of "pine" green. I always run a single wall 20 mm calibration cube when I switch filaments to set my extrusion multiplier. The red test cube had the last 3 walls right at 0.40 mm (measured in the middle of each wall), with the first wall at ...

The default PLA setting in S3D should work for HatchBox. It's pretty much bog standard PLA. I'd start with the S3D default PLA profile, and see if you can get a good extrusion multiplier setting. Once you can get a clean cube, then (and only then) move on to your model. The mess on the bottom looks ...

I use S3D, but I'm packing to go out of town for a week. I didn't see what brand, or material you are using. If you are printing ABS for example, I have no profiles for that because I don't use it. I mostly print with eSun PLA+, which requires a different profile from regular PLA. If you tell us wha...

I typically get +/- 0.01 mm on my cal cube walls once I have the extrusion multiplier set right. The first wall thickness can often be off a little depending on retraction settings & the like, but 3 out of 4 should be pretty spot on.
