Hi,
I did a search on "Calibration" and the 7 results did not answer my question.
I operate a plasma cutter using Mach 3, THC-1000 and Sheetcam. I am having trouble calibrating the machine, the motors are belt driven, and have gear racks. If the machine is set for 25" it will travel the 25", but anything below this distance gradually looses accuracy, 6 inches will be 5 7/8 inches.
If increasing over 25", I gain , 72" will be 72 5/8 inches. The machine is used about 32 hours a week, and is 3 years old. I am thinking the plastic or fiber wheels, spur gears or something must be wearing out. To compensate, I offset the drawing center and other features 5/32" on the Y axis, this has been increasing over the years. Any help will be appreciated.
Thanks, Larry
