Hi all. been trying various suggestions all afternoon with no real success. I tried bridging connection 10 to 12 and the 1st time I tried this, I had movement. Connected everything back up again (as it was originally) and tried it again; this time with no movement at all. The counters are moving on Mach3(all axis) when pressing up, down etc but no physical movement. I've tested the earth and it is good. There is no obvious damage to any wiring/cables. Fault light is still on the G540(as previously mentioned). Tested with test light on terminal 10 and get slight illumination(suggesting some power is there). Not sure what reading I should be getting on a test light though? Tried with charge pump on and also off and not made any difference. I have tested wiring on limit switches- have power going in and going out and breaks when switches are activated, until I get to last switch where I have 2 power(in and out). Not sure if this is correct? I've tested the E-STOP power switch and it is working as it should when tried. That's as far as I have got so far. Any further suggestions would be welcome please. :)
