Extrusion variance is one of the reasons why I was focusing on my extruder. I’ll have to try a different brand of filament though. I’ve been printing more or less exclusively in Pokymaker ASA. It’s cheap, and prints well enough, but I can’t find tolerance info on it.

Z-hop is not disabled, I’ll have to give that a shot. This is a Voron 2.4, which has geared and belted Z. I’ll have to do the math to see what the actual resolution per full step is later tonight.

I’ve given the gantry a once over twice now and everything seems square/right and moves freely.

Right now I’m thinking my order of attack will be:

• Try a print in atomic filament PETG since I trust the quality of that filament to reduce one variable
• Check belt tension all around
• Run through Ellis’s tuning guide
• Input shaper
• Print a cube in vase mode (I have a bunch)
• Disable thin walls
• Disable z-hop
• Reduce (or eliminate) micro steps
• Slow down velocity and reduce accelerations
