I have an R1+ thats stock besides an E3D V5. Today i finally got around to upgrading the firmware from an ancient version to 1.1.7. Everything seems to be ok, except that the Z axis seems to be compressed. What i mean is, if I tell Mattercontrol to move the carriage up 10mm, it only moves 5mm. If i print a test piece that is 10mm tall, the result is 5mm tall instead. X and Y axes seem fine, just Z. Suggestions?
