Hi Max,
On this last screen. The plugin spindle screen. I would untick the enabled box in the Spindle DAC section. I believe this to be only for 0-10v dc analogue.

Then goto the MDI screen in mach and type M3S100 and see if the relay switches.

Hi Hood, was seeing how long it was before you came to the rescue.

The mach spindle setup and output signals tabs look ok to me when I compare them to my setup.

Alan

Hi Hood

PM send to you

Thanks Alan

I will go and give it a go now. Will I still get the analogue signal to control the Super PID2?

Cheers

Max

Hi Max,
In mach it should be 4 not 12.  In the output signals screen it should be port 10 which is correct. But the PIN number should be 4.
And your wire connects to pin 12 on the output header

Hi Alan

I have un ticked the enabled box in the Spindle DAC section, but still Output4 does not change state

On the Mach 3 Diagnostics screen, when I inter M4, Output 4 lights up red, and it is slow flashing. Is it suppose to be flashing or is it supposed to be constant red?

Regards

Max

If you're using a Super PID, then you need to use two pins to control it.

You can use Output 4 to turn the spindle on and off, but you also need to use another output pin for the PWM signal which tells the SuperPID the rpm. This second output pin is what you need to enter for the spindle step pin.

On the Spindle tab, you also should be using PWM, and NOT step/dir

Actually, you might be better off using the analog 0-10V rather than the PWM signal, but you'll need some resistors to convert the 0-10V to the 0-5V that the Super PID requires.

CORRECTION
On the Mach 3 Diagnostics screen, when I enter 'M3', Output 4 lights up red, and it is slow flashing. Is it suppose to be flashing or is it supposed to be constant red?

Hi Gerry

I am using the analog 0-10V signal and turning it into a 0-5V signal via resistors
