Hi everyone,
I'm pretty new to CNC machines, I have an old gerber AR400 router which I have been running for the past few years without a hitch. Over the holiday period the x-axis has started playing up. At first I thought it was the stepper motor itself ( syn-slo nema 34 ) however when I swop the x-axis motor with the Y motor. .. the same thing happens ( total loss of torque ! )
I have disconnected and individually checked the resistance of each motor wire back through the machine and they all seem fine. .. am I right in assuming there is a problem with the drive board ? ?
I have had a quick search of the cnczone boards with no joy. . . I'd really appreciate your views and opinions
kind regards
Dave !
