Was cleaning my printer up and happened to notice all 8 of the 2.5mm allen screws that hold the hotbed to the z axis screws were loose? Anyone know of general or any specific Sovol Zero guides for regular maintenance? I’ve found some for head checks, belt checks but nothing for common screws to k…

Lately I have had some wild prints showing up, some would be fine then a reprint with no changes would just be a train wreck, artifacts, crazy ringing, and what looked like the nozzle actually dragging through the filament.

Thanks @SheepInACart that didn’t even dawn on me! LOL and I was tightening things due to expansion and contraction! Sometimes… :man_facepalming: That is a really good point! Cheers, -Mike
