Well there is a lesson learned!!.

Today I fitted the drag chain, and spent two hours drilling, and routing the cables through the frame back to the control box, Oh how neat it was, i fitted three bright new NPN-NO-6-36v proximity sensors to the X- Axis....LOL oh what fun that was.

Evertime i powered up the driver a sensor triggered, I didnt know what was going on.

I had used some 5 core cable for the steppers leaving 1 spare wire in each cable for the sensor, I had already run some wire up to the gantry for the sensor supply..

So now that i know i will have to use Screened cables on the machine so i dont get all these stray signals.
Can anyone suggest a four core screened cable that wont rip my arm off please, as i will wire the whole machine with what ever i get.

The drivers are 2MA860H Peak 7.2A AC50V-80V DC36V-110V running at 72VAC driving 4NM NEMA 24 Motors
