RE: [CAD_CAM_EDM_DRO] Re: Brdgprt CNC2 w Centroid

Well my Bridgeport was going to be loaded this week, but my experience with
cold weather is that Murphy likes cold weather - a lot. So I might not see
it for another week. In the meantime, should I find that a control axis is
bad, should I look to upgrade to something like Geckos or some other driver
that I could control with a PC? And what would be the cost to do this? And
is there any resale value to the Centroid system???

Thanks, C

One way to check the driver is to disconnect the bad motor from the driver.
Then connect one of the other axis motors to that driver and test run it. If
the driver is bad the good motor wouldn't run. The driver if bad can't hurt
the good motor.
