My printer started acting funny today. Its been printing just fine for the past week but today I tried to print a small round pulley and the printer is going all over the place. I’m using a gmax printer with a ramps 1.4 board my Y axis belt is taunt as is my X axis belt, the gcode preview in octoprint shows a perfect circle being printed out but something is clearly out of sync with the printer.
Alright never mind, the set screw on the y axis gear came loose.
