OK, found it.

It's basically the same one in the link. Yay, at least now I can see some wiring options.

The easy way is to use one of these relay modules triggered by a spare output A or B (Pulse or Direction). You can get the relays in singles or multiples at least up to 8 on one board.

Oh, thanks. Didnt know this was possible. Do you have a link or similar to one of these please?

They are all over eBay, just search for 'relay module 5v' and limit to UK if you want it fast.

Here's one example of a supplier - http://www.ebay.co.uk/itm/1-2-4-8-16...f5lyx157fF9xGQ

Awesome thanks

That should work well. Does it take much messing about with Mach3 to get this to work?

[cropwell]

I use P16 for coolant (just an air blower really) and P17 to turn the spindle on (Kress, not a three phase one with speed control)

You may like to play with active high / low and whether you connect to NO or NC on the relay as there can be some activity on the pins before Mach3 takes control.

So I bought one of these and finally tried to install it today. Nothing works. Ive tried every option. The state of P17 doesnt change, even if I press E Stop whatever. It could be that the board is damaged.

Are you able to indicate what the wiring should look like from a board like this please?

Sorry Chaz, but I can't get my CNC fired up at the moment. First, you need the relay jumper disconnected and then in Mach3 you need to command the P17 with an output set to pin17 and that output linked to M8 on the Spindle Control screen, so then M8 in your code sets coolant on and M9 turns it off.

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.
