Having issues with position loss. This is different than past position losses. I called shopbot the other day and went through steps afterwards of potential problems. Following is what was happening and steps I took to check for motor or control board problems: Heard binding/moaning sounds while cutting. Sounded like carriage was in a bind in some areas. Then after wards there were grinding or vibrating sounds as if the gears were slipping and positioning was being lost. After calling shopbot, I looked at the gears as I set it to jog back and forth. They were doing fine until I gently applied resistance to the carriage, as if it were cutting. The gears did not slip but actually began to just vibrate, almost trying to go in both directions. I dropped one motor and ran the same test for each side. They both did the same thing. I took both motors off, placed them on the table and ran the homing position command. Once I did this, I gave a little resistance to the gears and they were running strong with little or no problems. However, once I ran the jog command, I gave the same resistance to the gears and the were weak and began vibrating. I did each one and ending with the same results. Also, once I had the motors off I checked the carriage for binding and it was really smooth.
I emailed shopbot about my results but would appreciate any info from your vast experience.
Thanks Guys,
