you don't tick the active low in mach at all leave it alone, leave the red X yes the motor should show in the motor tab's use a OB motor Steve will come back with the M4 info

there is a new M4 ESS plug coming out soon, weeks if not days

I have the ports and pins changed to match what has been suggested, however I cannot seem to be able to map the Spindle on OB1. On the 'Master' drop down menu for OB1 on the axis mapping tab, it shows empty and doesn't allow the use of spindle. Should the spindle be set up similar to the motors and be called motor 2 and have step direction on pins 6-7 as well as forward and pwm on 14&16?

OB stands for out of band you just tick it in motors then in axis mapping you tick it then in the spindle setup you put what OB motor it is you don't set anything for it any where else.

then in your outputs you set the pin's

don't over think it

What I meant is that I select the OB1, for example, in the axis mapping tab, but it doesn't show in the motors tab at all, even when OB1 is selected in the spindle tab. When I exit the confi (after pressing apply) it wipes it...]

give a a couple of hours I will do a quick vid

Thank you, that would be much appreciated.

I admit up front that I know nothing about the Mach4 ESS plug-in configuration (and only bits and pieces about the ESS Mach3 plug-in config).  But it sounds strange to me that the ESS would map a motor to an out-of-band axis in order to send PWM for spindle speed control.  The PWM is *not* a motor.  I would not expect the PWM to take the place of Motor0, Motor1, etc.  But like I said, I haven't looked at the Mach4 ESS config screens.

as far as i know that's how its done a OB motor for the spindle it's like that with Darwin, if its wrong for OP set up speck up
 the OB are motors 6 to 9

looking at the 107 manual you have the pins select as it's says to do and set in the ESS config.

in M4 config select spindle on as your pwm pin 16 and spindle forward as the on off pin 14.

bob and Steve you sell a board that connects to a ESS why don't you know how to set it up. and should the op be using it with M4. if I am out off line asking this question sorry but product support is your name and word
