usb6560 Axis4 - Spindle speed

[Daved01]

Thanks again Andy
Tested M3 and 5 and the relay opens and closes as expected. if pins are assigned in the settings I do get a notice at the bottom of the software screen saying they are active and working.
I did have a thought that the manual speed control could be assigned (Need to test).
I was getting confused a little with the codes 3,4 and 5 in the way it is setup in the software next to selections for on/off, direction and speed.
My plan now is as I don't require the coolant function at this point, but would like the speed, I will hook my scope up to the flood and mist pins as currently setup, reassign in the software to speed and direction and see if I get anything.

I don't think you can control the spindle speed with this board as it doesn't have an analog output or speed controller built into it. The speed control it mentions in the manual I think is an analog Input where you connect a POT to control the Feed rate. The Relay is just used to Start/Stop the spindle.

Cheers Jazz.
I have managed to have another look at the manual, it does say that the spindle speed and direction can be done but I fear you may be correct. But not to worry when I get the spindle setup I will try with a potentiometer and then connect my scope to see if the PWM signal can be found.
I am sure it will do for now either way.
Thanks for the replies guys.
