When I want to control the printhead of the sigma via USB with Pronterface, I can not move the left extruder correctly. 1. Left Printhead moves a very distance when I hit the button for a “0.1” move to the right. 2. Left Printhead moves also to the right, if I hit the button for a left move.
The other printhead I did not test. I am currently using pronterface only, if the filament is stuck. But this is not really a solution for me.
Printings are running mostly fine, except the other problem I described here in the forum. Again: I am running the latest firmware (v01-1.1.6).
