I Wonder if there is someone alive at the Velleman support.
My post concerning the Nano did not even have any reply.
This is a printer I have to deliver to a customer.
Just a guess.
The rotary knob is it stuck so it’s pushed in all of the time?
You may need to realign the control board to make sure it’s free.
Rotary Knob was OK.
Solved the problem myself.
Took new controller Board.
First Print is running.
