The extruder heats up, the head moves to the home position.
Then, I see on the Machine Control Panel 'Communication' window that the software is sending a lot of XYZ commands in rapid sequence.
However, the printer head stays at the home position!!!
The printing task ends and the head has not moved a bit from his home position! Of course, nothing prints.
FYI, the printer works nicely when using Printerface plus Slic3r.
