I ran into a wierd issue today that I haven’t seen in my admittedly limited experiance so far. I was printing a quick fit wade’s Extruder, using known good G-code that I have used before. Everything was printing fine until about layer 45 or so, when the printer decided that layer needed to be twice the width that it should have been, but only in the Y axis direction. I’ve seen the Shift print X mm over to one direction issue before, but this one, the software literally told the printer “make the line 40mm” and it said “80mm? Great, sounds like a plan”.
Any ideas what would cause that? I had been printing a fair amount of stuff beforehand, but I’ve printed longer without issue before this. I’m thinking it either has to be a controller glitch, the encoder on the Nema motor, or a computer / USB glitch. The hardware in the computer is solid and displays no USB issues so i’m inclined to rule that out. but what else it could be, I’m at a loss.
