    matsuura 500v trouble- spindle will not start

    It looks like the source of the trouble has been resolved. I received a bit of an education on how to inspect the voltages and when I measured from the limit switches to a dedicated ground terminal, I found the spindle detent ("key lock" according to the manual) only has 14 volts across it...

    matsuura 500v trouble- spindle will not start

    SeeFair, Huleo, I must start by admitting I am not much for electronics, though I am learning. I agree on checking at the control. On the spindle drive, I see LED lights, but I have not found diagnostic information to make sense of them. I believe the spindle drive is a yaskawa type...

    Help! getting computer to talk to BTR, Matsuura, CIMCOM

    Just wanted to post an update, the "BTR" from western numerical control (WNC) wasn't. That is to say, it was an interface between a dos based computer and the machine.

    First CNC Mill. Matsurra mc500v. tool length setting help needed (GENERAL HELP TOO?)

    Volitan, your procedure fits with the manuals explanation. The buttons you refer to would be in the center of the control panel for my machine, however there is a orange metal matsuura decal placed over the holes for those buttons, right under where TLM is printed on the control panel. I have...
