Are there any error messages? Can you jog any of the axis?
Does it still have the chiller error?
Why are the onsite fellows that charged $20,000.00 not providing any type warranty service?
Are they paid in full for their service?
How about posting good close up detailed pictures of the switch repair that was done, maybe a extra eye will see a problem.
Do you have all the service manuals in pdf format?
