Printer is brand new. Went through the basics of properly leveling, calibrating each stepper (Including extruder) and running several test prints of the XYZ cube until I got it right. I then printed a Left under bed support bracket using Creality's native slicer. It took forever so my friend recommended this software. Immediately I could see the difference, the print looked better made, smoother and stronger....
That is until about 2/3 through the print the head started going in a completely different direction hovering over nothing and started spewing filament into open air.
I thought it was a fluke. So I queued up two smaller parts for the back plate braces of the supports and about 20 minutes in, did the same thing. Any ideas? Why would it start perfect, then partially through the print go haywire?
Pringting off SD card, not USB. Any ideas would be great. I'd much rather use this program than the very basic Creality slicer.
