Hello,
I'm have an issue while printing. When I am printing a square box and the machine will print 3 layers then it would go to home in on direction and then go back to the object and continue printing. I'm not sure what s going on. I had to replace the Arduino and I uploaded the same settings I had on it before. My printer in a costume build of mine but I am using a ramps 1.4 with Marlin firmware 1.1.0 with crafware slicing program. I am also printing from an SD card. Thanks in advanced.
