After tuning my vref, the printer was missing steps still. I pulled the trigger and am swapping from the 4.2.2 to the 4.2.7 creality board to see if that resolves the issue.
While i was in there, I figured I’d put another z axis motor on there.
Do you guys have any recommendations on firmware or should I just stick with creality’s?
The difference was that these printers were installed in bakeries, and were printing edible ink onto edible paper. If the owners didn’t keep up on basic maintenance or general cleanliness, there could be a fair amount of mold, or - far more often than you’d hope - lots of roaches.
