I'll take a pic of the tool height setter tomorrow and check those other suggestions, but wondered if I touched the two plug terminals of the THS with a circuit tester and apply pressure to the pad would that make or break the circuit and tell me if it works or not??Don

First unplug the THS.
Now basicly you want to be able to short the 2 wires of the socket leading to the control box NOT the THS. This can be done by bareing the ends of a short length of wire, attach one end of wire to 1 pin, any it doesn't matter which, while leaving the other unattached.!

Now push the button to set tool height on the pendent and it should start to work like it was going to set the tool height.! Before the Tool actually reaches the tool height setter pad short the other end of the wire to the other pin. This will send the signal to the control just like the THS would.

If this works like I've just described then it's the THS thats faulty or has a broken wire. If nothng happens when THS disconnected then it will need further investigation.

Other things it could be are:

The remaining wire to control box is broken.
Faulty or damaged input on the break out board.
Software issue
Pendent faulty (Should be able to confirm by manualy activate THS setting routine by issueing a M code starting the THS macro, obviously will need to know the macro code to do this.!)

EDIT: There is a quick way to tell if the THS setters broke and partly verify software/pendent is ok without shorting wire.? . . . . Unplug THS then push pendent button if the machine starts the routine like normal the hit the ESTOP before it hits anything.

Hi all

Sorry for taking so long to reply, just been one of those weeks.

So from that useful advice it seems the THS is permanently on if you like. I also put a circuit tester on it and found it's connected all the time as in doesn't matter if you push down on it or not. I then tried running the THS routine without it connected and it starts the routine fine, so am guessing there is something wrong with THS, so have contacted the firm to see what they say.

However they didn't reply to my last e-mail or return phone calls so fingers crossed they reply this time.

Many thanks

:)
