I realize that this is an old thread, but for some reason my power supply fan seemed a bit more obnoxious than usual today. I suspect it's because other common noise sources in my shop were quiet today, but it got me thinking... The Noctura fans mentioned in this thread were rated at 20% less air fl...

So, my question is: Any idea what cooked it?

My wife refers to this process as "being confused at a higher level, and about more important things..."

Sounds very promising! Thanks!

I checked out a few reviews, and Prusa 2.x seems to be ahead of Cura these days. The (vague) similarity with S3D will also help.

Thanks! Which flavor of M2 do you have? I've got an M2E. One reason I've been nervous about switching to Cura is the only profile I've found is for an older version of M2 where the Z axis stop is at the top instead of the bottom, and people reported having the platform slamming into the extruder whe...

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...
