Proximity Wiring Problem

[JAZZCNC]

Thanks for your reply Jazz

I thought i might have cross wired the sensors that are in position on the machine, so i used two spare sensors and tried a direct connection to the board with the same results.
I will get some new sensors from a reputable supplier.

Did you try the spare ones individual.? Or both wired parallel.

Have you got a spare power source and say a relay or lamp so you can test them off the machine before fitting.
