I wasnt active as I wanted to. In the meantime, I managed to run old Welturn version in LinuxCNC with Samco's help. It ran nicely, but a bit slow for my liking. I replaced all the electronics now, and it has modern steppers, running at 1.2m/min (could achieve more, but I would need to replace the power supply to 60V, over this speed steppers stall with 48V). I am thinking about replacing them also with hybrid steppers with encoders.
