Mach 3 I have installed on win7 32bit. Before 14 days the problem arose, With the axis began to lose the steps. I checked the mechanical circuit cnc, replaced the leading bushings. Mechanical damage does not appear. Because I did not fix the errors, I examined the wires. I changed all the wires from the FB25 to the controller and I changed some two-way terminals to the cord connector, but the error did not disappear. I tested the driver test. The test most often showed the pulse is too fast and sometimes the pulse is too slow. Could he blame the computer for dropping the steps?
