Problem with my Gecko G540 control unit.

Machine was working so doubt it will be Charge pump unless the Parallel port as gone Tits up.! (Which does happen)

Alan charge pump is safety function where the G540 will only turn on it's outputs if it see's set frequency coming from the Parallel port. So you must have the parallel port cable plugged into PC other wise the G540 won't see the signal and remain inactive. To eliminate this from the search you can turn it off using the little switch in the bottom right corner.

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. :)

Further update- when charge pump off on switch, I have a green light on the G540 and motors engage(but don't move). When charge pump is on, the red fault light comes on again.

When you say tried jumper wire first time have you tried jumper wire since re-connecting orginal wires and now it doesn't.?

Can you post some pics of wiring.!

Not 100% sure really but perhaps the parallel cable or the wiring or something else!!! I've tried so much over the past few days, it's hard to tell!!! The most important thing is it's running again, so we can continue cutting orders for our customers.

Spoke too soon!!! The following issue is now occurring:-
Start program and the machine cuts for approx. 30 seconds. It then stops and the E-Stop lights up on Mach3. A page then pops up saying something along the lines of 'automatically toggle switches to on/off position'. I click on that then reset the E-Stop on Mach3 and no motors move but the XYZ counters continue to move but the router stays in a fixed position. Getting very frustrated with this now. :/
Any ides please fellas??
Regards,
Alan

Most probably electrical noise on your signal lines. Try adding a little De-bounce which you will find in the General config screen. If this works then you should check out your wiring to make sure signal wires are not running too close to high voltage wires.
