Thanks again TPS !

Ok - so the Z moves up now.  I dont think my limits switches are switched on, as none of them work.  How do I switch them on?

In case they are faulty, I have attached a picture - do you know what this is?

Many thanks
Anthony

normaly first Thing is to figure out how they are wired to your Controller/ parallel port.
on the Picture you posted i can't se any wiring at all??!

and after the wiring is clear in Config -> Ports&Pins -> Inputs
anything is possible, just try to do it.
if you find some mistakes, in my bad bavarian english,they are yours.

Hi TPS, thankyou again. It seems that he wiring goes straight into the plug - I put a voltmeter and the voltages are shown.  the + was connected to the + of the voltmeter. it looks like all inputs go to Port 1?   Is -2.67V correct - I found that image online and it says its 5V input, but it is +.

The issue is, I dont think its a 4 wire sensor, uless there is resistors hooked up inbetween the sensor and the plug?

Thanks TPS,
Anthony

if it is an optical sensor, i think there should be an external power supply (5V) somewhere.
is there no Manual of the Controller box?
anything is possible, just try to do it.

Thanks TPS.  There is no external power supply - the person who made it had everything in the box. No manuals.

So I suppose I need to open the box and  check the power supply to the sensor?
