Hello everyone, Before the servo failure, the precision of the machine was still in the / 100 mm. Certainly due to the weight of the head.
I'll start by changing the cables defective. Then we will dismantle the screw to examine. Thank you for your valuable advice. I will continue my work with linuxcnc. I retrofit a tour with Jon card.
