I need some help please. I have a few Anet A6 printers. They have been pretty reliable printers so far. I printed a large round piece for a buddy of mine the other day and the print came out great, like always. Now for some reason, this printer cannot print a circle. It looks more like a trapezoid circle, if that make any sense. I have checked the belts and they are good. I have checked to make sure the machine is square, and it is. It is strange that it just started to do this after this large print. Everything seems to be moving smooth, doesn’t feel like the bearings are bad. Anyone ever experienced this before? I have been printing for a few years now and usually can figure things out. This one has me stumped. Thanks!
