They are not being used any more. For some reason people thought that an exception was made for extruders or something. And people keep adding them for the definition files too. I'll add a test to prevent that.
Definition files for single and dual head versions of Velleman Vertex
K8400 printer.
The machine uses printable coordinates x=0 to 200, y=20 to 200 and
parking position 200, 200 regardless of how many extruders you use.
Thereby the different machine_width for the two models.
The g-code can probably be improved.
USB connection not successful this far.
