MACH 3 or LINUX Conversion on my Denford Lathe

Re-calibrate your expectations.
Imo.
Ime.

A csmcio-ip-s costs 1500, +/-, for the controller alone, dc psus, conduits, standoffs, ferrules, boxes, cables etc.
Wiring everything takes 2 days, when you already know everything about everything, and have done it several times.

Does the spindle have an encoder ?
If not, how will you or someone add one ?

It took 200 hours to do my first good lathe re-build circa 2006.
It took 200 hours to do my next saddle rebuild last year, on 750W ac servos. Details remain.

A linux+mesa hw may cost 1000$ less in hw, but all the work remains.

A basic ghetto stepper system can be set up in 2 days, if brackets and spot-welded stuff is acceptable.

2 ac servos, 60V DC, 400W, pulley drives, psu, would cost less than 1000$.
(390€ each servo).
A pokeys controller would work, 150€.
One would then need to mount/fab brackets, align everything, typically get pulleys bored to size on the driven ends, etc.

I already have a fanuc servo lathe, so I don't need servo level performance.
I don't understand why anyone would sink ^^^^ that sort of money into a hobby machine, in fact I doubt most hobby level machines have the rigidity to match servo federates
A reasonable level stepper conversion is all I need.
Got one arranged for 500.
Thanks

Em..
You wanted commercial quality, and commercial threading, in Your post.
Threading was a requirement.

After 2000+ work hours on threading over 12 years I have very strong ideas on what why and how some things work, or not.

Never meant to ruffle feathers.
Let´s see how your stuff works out, ok ?
