Re: LO-X7 XY Limit Switches Inop

OK, I found the problem. One of the control cables has a female pin that is crushed inward and not making good contact with the male pin on the control board. I got it "augured" out a bit to get the machine functional again, but will need a new cable ultimately. I have no idea if that cabl...

Re: LO-X7 XY Limit Switches Inop

So everything was working fine until just the other day ... I was assuming you were correct and a plug was not properly seated. So a couple of days ago, without any changes at all, the machine starts trying to reverse home ( x and y axis going opposite direction). So based on the previous solution I...

LO-X7 XY Limit Switches Inop

I’ve upgraded my K40 over the last week with the LO-X7 DSP, LO-60W PSU, and the LO Z-axis table … potentially a very nice setup.
