Amateur wiring pictures as promised.
I have rechecked everything again and seem to be getting 4.95 volts on every terminal and gnd with the slot there or away. What do the resistors do as I get 4.95 volts after them and to gnd. Is there a right way round for resistors?

Looks ok I think. I am OTT today at the workshop, always happens on a Friday ::) but will try and get a chance to look out for an opto and test it.

Ok found an opto and tested it out and it does as I thought (5v on blue to black when open, 0V when blanked) so looks like your is faulty in some way.
Just to confirm, you tested it without it being connected to the breakout board?

Hi Hood
In anticipation of your results I ordered another opto 917B should arrive soon possibly Monday.
I tested all the wiring with it disconnected from the BOB as you asked.
Stuck now till it arrives will keep you informed of progress.

New opto came late this afternoon, fitted and all systems working. :)
Tommorrow I will run the screwcutting wizard to see what I can accomplish.
Again many thank for your patience and quick advice

Wondering if someone could take a look at another Opto Sensor type. It's the HOA1405-001. It doesn't require a slot because the IR LED and the Sensor are pointed at an angle to each other so all that's needed is a reflective spot.

I'm just to ignorant to make a definitive call on how the wires go together.

I'm using the cnc4pc c11 board.

My thoughts are as follows:
C - Input Pin on BOB
E & K - Wired together and put on GND of BOB
A - Place 220 Ohm resister prior to connecting to 5V on BOB.

Any advice would be appreciated before I destroy something. I don't want to fry the IR LED nor burn out the Sensor. Also want to make sure I put the Ground wire where it's supposed to go on the c11 as well.

(I'm still attempting to touch base with Arturo but haven't been able to talk to him in weeks now.)

Talked to Arturo and got some other things sorted out, but we didn't get to work on the above post's question about wiring the opto.

Anyone got any comments?

Hi All
What would be the best way to achieve full motor control on my Colchester Masster via Mach 3 with the attached old motor.
I am converting single phase to 3 phase via a 2 hp Motorun convertor.
I have a spindle encoder but want to introduce stop/start, forward/reverse and constant cutting speed.
