If you are controlling the speed of your spindle with LinuxCNC instead of just
ON/OFF/DIR, how are you doing this?
Step/Dir?
0V-10V PWM?
ModBus?
If ModBus RS232 or RS485?
Some other way?
Thanks

My spindle is driven by an Automation Direct GS2 drive. I am running it via
Modbus over RS232. It seems to be working fine. I don’t have a spindle encoder
installed.
Modbus components in LinuxCNC are not real-time.
I don’t know what that implies.

My lathe uses RS485 and the hy_vfd hal component. My mill uses analogue
0-10V from a Mesa card.
The other way round would mak

How are you generating the 0-10V?

Here is one way:

In fact my mill might be using that. I would need to look :-)
It's something that you can "dead-bug" and have in the middle of a cable in

Well, on my Bridgeport mill, I use a spare channel of my
analog DAC to deliver 0-10 V.
On my minimill, I have the DC motor run of

I’m using PWM with a direct signal and enable.My drive accepts 0-10V, so I
created a little board that converts the PWN to a
That part is perfect. Didn't know there were opto's like that out there that
could have a VCC of 10V.
Thanks

That's basically what I've drawn out too but I found the op-amp couldn't pull
