Gene,
Do you know which source code file has the G33.1 control? I'd like to look at
how it's done.

Thanks for that Jon. That helps explain this a bit further. I believe the
base period in the ini is set to 100,000. Not sure if that is nS or u
value? Can this be change to suit or is it tied to the speed of the system?

I’m getting confused by the reply’s on this thread. Lol.
Anyways, the tyco relay is rated at up to 28vdc switching voltage so which
equates to roughly 1450 rpm. I doubt I would be reversing anywhere near
that load level. I would expect the reverse would occur at near zero rpm
—assuming a G33.1 ope
Thank you, Gene.
Got it.
Looks like I have to take the Python book from the top of the shelf, and put it
lower.
Firefox is my standard, so the lack of Internet Explorer is no hardship.
Reading this Wiki puts my buying a VFD back by some reading time.

I should have mentioned, I’m in the process of building a reverse polarity
circuit to trip polarity by issuing a CCW M4 via a 5v output. My motor
controller doesn’t natively support CCW.
I entered the code and it made it all the way down until the spindle
stopped. No reverse so it stayed there.
Thanks Jon. My max jog speed is 54 IPM so I should be good to give that a
try. Thanks for the test code!

Thanks Gene! I can go down to 48 PPR on the encoder. If I do so, what is
the trade off for reducing resolution on my mill project? Is that enough to
successfully use rigid tapping and synchronized feed/speeds?

Why certainly Gene (see attached). I actually have it working a little
better now. My spindle-at-speed LED will start going bonkers around 1200
rpm. I'm guessing this is when the counter "throws up it's hands and says -
I quit!" lol. The spindle will operate all the way to around 4700 rpm but

Its (the PID is) a waste of processor time if open loop. I don't use one
of those in any spindle run by a vfd, the vfd is generally stiff enough
control by itself.

Oh, so the situation with and without spindle-at-speed were
BOTH open loop? That is
totally different, then, and now I have no idea what is
going on. But, checking all signal

Is there a simple test code I can run to confirm ridged tapping is working
or even the feed rate is synchronized to the encoder feedback? Without,
spindle-at-speed enabled I’ve no way to visually confirm this. Or at least
I don’t know how. Lol

I’ve confirmed the fluctuation occurs when spindle-at-speed is configured.
When I remove this feature, the spindle rpm appears to stabilize. It’s
almost like it gets caught in a loop trying to chase its tail.
This is VERY common in servo systems, and
Very good read. Thanks.
