Blobs/Zits on Walls with Octoprint

When I saw that thread title before making this post, I (stupidly) assumed it was actually for an arc welder 🤦♂️... looking closer, I think this is solving my exact problem!
The buffer underrun that is caused by too many g-code commands, do you think that would be mitigated by a newer Raspberry Pi? I figured my 2 is a bit long in the tooth anyway.
or is it more of a bottleneck caused by the USB protocol itself?
Edited by dfrezI would say : a bottleneck caused by the USB protocol itself
You could also try lowering the tessellation of the model when exporting it from the modeller you use.
Since I wanted to be able to access both of my UM2's through Octoprint, I ended up getting a Raspberry Pi 4 (didn't want to mess with trying to run two instances on the same Pi). I printed the same exact models that caused blobs on the RPi2 and they came out flawless with the RPi4. So FWIW, it does seem that part of the issue can be caused by an older Pi. No post processing with the Arc Welder plugin on either set.
