Hi,
Im new here, and Im going to take a stab in the dark and see if anyone is familiar with this type of a problem
We have a Bridgeport type mill with a dynapath 40 controller. The problem is, that everyonce in a while the X axis looses its location/jumps and needs to be re homed. its an x/y table motor controlled. All the computer hardware has been checked out with no problems. We havent looked under the table. The problem happens once in awhile with no way to repeat it. The axis will be moving or rapiding to a point and the operator will discover that the position is off .1 .01 .05, etc with no servo, or computer alarms.

If anyone has ever had this type of a problem please give your input. Ive had several machine repairmen in to see it, and no one can solve the problem.

thank you
