Last week I had a stepper motor stop working. Trotec support was outstanding. They sent the replacement overnight and I was only down one day.
Taking the motor out was a breeze, getting all three screws back in was an adventure.
My salesman came out today to follow up and make sure that I had proper tension on the belt.
In three and 1/2 years this is only my third day of being down.
Just sharing my experience.
