Boxford TCL125. (Fresh start )

[inee]

Forgot to mention the photointerupters, the photointerupters can be powered independently, so can attach to a supply board(not sure of the operating voltage so hold off for a tick.

You have 2 one changes state once per rev of the spindly the other changes however many times it sees the holes all around the disc ,I'm not going to count em ;), but the clue is in the naming of the signals on the diagram.

In mach or other software the single hole wire will be the index wire.
the multi holed wire will be the timing wire
Some software can't pickup the index pulse so then after checking the signal changes, you may need to open out the single hole, to i think 6mm wide ,but do it a bit at a time and retest until it picks that signal up in software's.
Hope it helps

a I've attached a diagram which should hopefully guide you in how the fed/rev relays work, bear in mind that rl2 represents the no/nc connection on a bob and although d
drawn with one wire in from 0v there will be two, i purposely left it like that so you can see hoe it works, the blue wire simply represents the way the 0volts is switched to trigger rl3.
Can i ask a favour, can you let me know which buttons on your control panel are ,on/of or momentary operation.
