Hi, I have limited capability on the Z axis. The axis will home to the mechanical switch limit and then drop to a point which I asssume to be the fiorst zero point below the mechanical switch limit. Then it gives the error. There is power to the mo

Slot 11 in the I/O box is the one for B.E.C. pcb, the offset is 2125 in the x and 500 in the y axis. The template for the B.E.C. is triangle in shape and is the length from corner to corner on the rotary table. You can also type in sh sys and look to

Hello We have a GSM machine with two heads from the universal company, currently the machine fails to zero and in production mode, when the heads increase the displacement speed in the Y axis, they stop immediately. And the error illustrated in the i
