stepper motors which have plugs on them with yellow brown white and green wires going into them...

That sounds like bipolar to me... 4 wire?

If you want to just get going the least expensive - $10 break out board, couple stepper drives and a computer with a parallel port would get you cutting.

You could also make really nice threads with a 25 to 100 line encoder + index. (parallel port would handle that too)

I have never heard of this.. (I have a compact 5 pc - which uses the printer port..) I have a config that works with the stock compact 5 pc (plug and play) with linuxcnc.

Looks like a cool little machine. Have to know a little more about it! Did you get any of the electronics?

This was what I was machining.. I want to machine/thread the back side of these so they will spin onto the nose of the turco.. Then I will have a few er20 holders that I can have a few tools setup for machining.

CSS and FPR

more goofing around...

another painful update

face plate mounted... Need to drill and tap a bunch of holes.. Getting there...

roughed out the back of the face plate....

I plan on using at a lightweight 4th axis.. For either the turco or my 440 sized machine.

and another update...

started an actual 4th axis........

Thought this would be a neat experiment to see if a minimally printed harmonic drive would work (for some definition of..) Just printing the flex and outside gear.

some more

I cannot find those style collets... I ended up buying a mt1 to er16 and modifying it to take the nut. I will probably make more when I get the chance.

That is an awesome count for printer port reading. The emco compact 5 pc's have 100 holes + index and they work great over the printer port.

Fun little machine.

The main reason why there is only a pi4 version is it is the first pi that can really handle it... (main thing is that the ethernet controller is not connected though the usb bus anymore. This allows for actual realtime ethernet attached devices. (like the mesa 7i92 or such)

BTW - David - what kind of encoder is on the orac?

Some more fun with cnc...
