Print overlap and shifting
Just put together my i3 MK3 and am having problems with the SD card loaded test prints. Pictures attached. There is come shifting and perimeter overlap that I can't figure out. I checked belt tensions and set screws for pulleys/idlers and everything seems ok. I haven't tried changing any slic3r settings to run new gcodes because with all the different possibilities I have no idea where to start. If someone could give my some ideas to look at it would be most appreciated. Thank you.
Re: Print overlap and shifting
I think you have tightened the bed's bearings too tight (U-bolts) or the belt end pulleys do not rotate free. Loosen the belt and check that the pulleys and bearings slide without resistance.
Then make a first layer calibration again.

I checked the ubolts but they were not the problem. Turns out the x-axis pulley was very loose. Tightened up then tried printing again. Perfect! Thank you!
