I am pretty new to the 3D printing world. I have a Mbot 3d Grid II.
Couple of days a go I found one of my print stopped in progress. Nothing moved. I canceled the print, and tuned the printer off.
After trying to print another project, I noticed when the print head moved forward it was fine, but as soon as started to move back the print head started vibrating.
I reset the printer to default settings and wanted to level it, Than I noticed the printhead does not move to his starting orgin (back right hand corner)
What can I do to correct the problem?
