The differing opinions make it very confusing. Even in that thread linked above, some disagree with Mariss, despite his perfectly reasonable explanation.

Hood,

Curious, would you have been able to use the spindle as an axis if you weren't using the encoder module?

Also, why do you prefer velocity mode? Thought torque mode was the preferred one. Mariss describes it very well in this thread:

Hi Hood,

Yes, it's starting to look good.
Didn't know the CSMIO had an Auto Tune option. Sounds great! Also the DROs keeping track of the axes backwards very interesting.

Dan

Thanks a lot for information, Hood. Just what I needed to know.

Dan

Hi Hood,

A quick question regrading MPG with the CSMIO. Does it work in Step-Velocity mode as well? Or just multistep? What is your step size at x1 ?

Dan

Yes, Craig kindly sent me this code a couple of days ago and it works well and I even like the way it sets next line and reports the new with the previous one. But like you, Terry, I haven't yet figured how exactly it works.

That idea of looking for a "(" is nice, but sometimes I am lazy when adding comments manually so use the ";" character instead. Should I be able to look for it as well and then for a CR to reset the flag?

Dan

Hey Terry,

Thanks for the code!

Doing for Turn, what if we OR gated the following in the If statement: "T0" OR "T1" OR "T2". True, not an elegant way, but it will do what's needed. And I don't have tools on the lathe past 29. If I had I could just add another one to the OR: "T3" and so on...

Dan

Hood,

What MAch version did produce good threads? Was it 057? Or an earlier one?

Dan

Charlie,

If you meant the PWM, then it has nothing to do with Mach3. What provides this is the Smooth Stepper external controller, which does it locally in its hardware. With the parallel port you cannot do this.

Anyway, as mentioned by others above, I would guess that you may not really need this for the things you're looking to do.

Dan

Hi John,

Glad you got it solved.
