I’d like to help on this, who’s the right person to get some tasks from?
That would be me, I will come in tomorrow and take a look at Rich’s box and plotting things out. What makes this interesting is the fact that signal wire will be going to the motors not stepper pole wires.
Yup… Ole Mach 3 was pretty good to drive Steppers… Link is to my old table top CNC I built many years back… ( video isn’t that good )… The home brew driver PCB used ST Micro’s L297’s & L298’s …
Plenty of circuits to build a stepper controller that Mach 3 or 4 will drive, on the internet… If you want a High Quality one you may consider a GeckoDrive…

Made some progress tonight. We mounted the components & start the wiring. Turns out we do not seem to currently have any 7/8 stepbits. Had I known I would have brought my own in & saved me an hour of looking.

So I soldered the leads on the quick connects tonight. Chris Wischkowsky the other day wired the steppers to the female quick disconnect end. No pictures today, I have to replace the glass for the camera on my phone tonight.

Forward Progress. She shall be dubbed “Side Chick” lol. We still need to do limit switches, wire duct & some smaller finishing touches.

Looking good!
Is that under program control or manual control?
Just manual. We were having issues just trying to get it to move. That’s a long story in itself, but we got it.
I forgot to add a picture of what the wiring looks like so far. We have been tempted to do an auto speed control for the spindle but in the end we don’t think it can be justified. But we may add it later.

Nice clean wiring job.

The first cuts on the CNC Sherline. This was just to proof to run. We need to get a CPC connector or something similar for the spindle.

Mounted the drive in an enclosure for more room for potential upgrades in the future of a speed controller. Tied the CPC connector in on the outside, still have the inside to do. Obviously I still need to do cable management which I have a few different things for it.

Slowly forward progress.
I tied in the speed controller to the CPC 7 pin connector, installed a solid state relay, put in a fuse holder, & put in strain reliefs. I went to run the cable from the main control box to the motor drive & found that someone ran off with/moved/misplaced my SO cable.

Forward ahead.
I wired in the 120 into the fuse holder, wired the 120 to the motor controller( sorry for the EU wire colors but it was the only SO cord we could find at the space), re-ran & placed the manual speed control knob.
So what’s left you might ask.
Ground wire to the case, wire the pilot(low voltage) side of the SSR & cable management. We have all the cable management items at the space to tidy the exterior cabling going to the steppers & limit switches.
