You can use any spare axis pulse or direction pin to do the same thing btw, if you want to use the onboard relay for spindle control, which is hard wired into P17 when the jumper is on.

PM me your Mach3 configuration file (you will need to copy it and change the extension to .txt) and |I will have a look at it. I can't remember exactly where we got on this.

In the meantime I will look at my CNC PC to see why it is not firing up properly !!!! - Have looked at it system SSD is dead, will need to rebuild Operating system and reload software --- S H I T -- !!!!
Thanks. Ill get the config later (its in the garage).

I tried with the relay setting on and off. I did damage the board however previously when I miswired the on board relay. Cheap enough to replace. I then made Output 3 try both pin 16 and 17 but nothing changes the state of them. Im using output 3 for coolant and triggering it doesnt change anything. Perhaps I need another board first. Id love to go CS Labs as its something I understand but too pricy for a machine ill likely be selling.
