I think you guys are a little harsh on TT350........
As I see it he made a reasonable question and said he was sorry for the typos. Can't we be a little more relaxad here? After all we dont compete with each other in here, we are here to ask questions and share information.

I just did a test. CV mode is indeed active on a rotational axis also.
I tried this code with a very high feedrate, very low accel, CV on, CV distance 10 and CV speed off:

Y200
A200 (Rotational A)

By simply looking at the toolpath window it is clear that the A200 move starts well before the Y200 move is finished, probably 10 units before.

All in all a very good job. I now see from your drawing that the requested tolerance is +-0.05mm which I think should be fairly easy to acheive with your setup.
I had a closer look at your code. I'm not very good at writing/reading G-code but it looks like you have lead in/lead out for the rotational cut also. In combination with CV mode that maybe leads to no short stop at each line containing a rotational move. Maybe I will try to run your code cutting some air and have a very close look at a zoomed toolpath window trying to see if CV is active when running a rotational move also.

If I understand you correct you want to control the angle and not the linear movement.

If so, I would have fitted a servo motor system with an encoder measuring the angle of the rotating bracket, not the rotational position of the motor, giving feedback to the servo motor drive board. Such a system requires minimal or no backlash on your drive system but removes any complicated angle/linear conversion from Mach3. Mach3 will put out, and the DRO will accurately read, the position in degrees.

One thing to be aware of is that the VFD creates noise in the supply line also. This noise travels back the supply line and can enter the SS through it's power supply. How is the SS powered? Does it have it's own 5V transformer? Does the supply line for the VFD run near other lines which maybe enter the control cabinet? Which make VFD is it?

Now it plays in Firefox :-)

I do NOT love Microsoft!

I cant view your video. I'm using Firefox.

Maybe drawing a polyline instead of a splin will help?

Yep, if you have a G61 in your G-code, then you find yourself in Exact Stop Mode.

What is the feed rate setting under the settings tab? And is it active?
