Yes, I noticed, but still no value here.

No. Spindle PID not the issue. Available, but not required in PWM (Used trimpot on module to give good speed control for all functions).
PID not available in OB Spindle (Not in this setup anyway).
There is an issue in the OB spindle Configuration, that only occurs when screwcutting, Perfect for all other functions.
No amount of PID adjustment will fix this.

Now Using Mach4 4.2.0.4469 / ESS V256.
Using OB Spindle, still not working but different (Possibly setting of motor) Motor running at set speed to start of screwcutting, then Speeds up a bit, with a definite fluctuation, before settling down to a stable speed. Conclusion - Someone (Warp9 or Artsoft) is still Stuffing around with the set speed.

Thank you Brian for suggesting PWM spindle control, Got the PWM-Voltage board and set it up today on the lathe.
PERFECT… No fluctuation in speed at all. Just what I needed for screwcutting. Will cut some threads in a day or so, but (hopefully) nothing can go wrong now.

Possibly time for an update?
Hope you get it all fixed soon.

I don't know if this helps, but just been out running mach4, Viewing photos, Videos etc over Wifi and internet No issues, mach4 kept on Going fine. I use an ESS, maybe a problem with your plugin.
My computer that I use is a reasonable spec laptop from about 6 years ago with a clean install of windows 10 64 bit.

Brian. Thank you, but already have the latest ESS Build 253. On the warp9 forum, an issue with OB spindles (sounds like the one you mention as fixed above). Hasn't fixed my problem. Will try PWM to Voltage board when it comes (Will post result). Also looking forward to ESS build 254 (Coming soon !). Just downloaded Mach4 4.0.0.4446 as beta, will sit on that, as problem seems to be ESS.

Jose Luis. I have a Mach3 style single pulse per rev index pulse in Mach4. However it does need to be configured in both the Mach4 Control and ESS Plugin. In Mach4 Go to Control Config / Input signals tab and find "INDEX" (Well down the list, near Estop). In ESS Plugin, go to input signals and find "SPINDLE INDEX (RPM INPUT)".

Hope that helps.

That's good of you. Thank you, it will be a big help if we can get this to work as is. Primarily this is my development machine for Ezilathe, and I do need to get back to mach3 periodically, just to check I haven't stuffed it up, so less hardware changes the better.
Managed to get a simple PWM - voltage board on ebay, cheaper than buying the components here, not much of a change to the hardware if required.

My spindle drive is a Chinese AC servo motor (very good, inexpensive, using them a lot these days) but no Modbus in mine (Option only). This gives me the capacity to use spindle as a Drive "C". Very handy.
The mention of RS-232 these days brings back too many memories of days spent fiddling with cables and protocols on old PLC's. Probably will consider Modbus, but not yet.

Never said I cannot control the speed. ONLY in Screwcutting where something other than I is in control of the spindle speed (and stuffing it up)

Craig. yes back where this post started.
I have a problem with Mach4/ESS/Step/Dir Spindle Control ONLY when screwcutting.
All Other functions good. Mach3, same hardware good.

My spindle control works perfectly in Mach3 and Mach4 for everything except Threading under Mach4.
My spindle motor has plenty of power, and in normal turning, spindle speed does not vary at all from no cut to heavy cut.

The issue here is that I need Step/direction control to operate the C11's voltage output, and there is seemingly an issue with ESS/Mach4 when spindle control is not based on PWM. If you do know how to set a C11 board to Control the output voltage based on a PWM signal, Please let me know.

I cannot think why it is an issue, all I expect of the spindle speed control is to stay where I set it, without the ESS/Mach4 virtually shutting off the spindle at the start of the cut. It just needs to match the feed to the indicated speed. Further up this post is a link to a YouTube Video that shows what is happening very well.
