I upgraded to Marlin 1.1.7 following this thread on my R1+, all seems to work, except that my Z axis seems to be out of whack. If i tell Mattercontrol to move the Z axis 10mm, it only moves about 5mm. Printing a test piece that is 10mm tall, comes out at 5mm (with various skipping filament). I dont have an LCD or anything, and besides an E3D extruder the printer is stock. Any suggestions?
