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.

Cheers,

Thanks. Appreciated. Ive emailed APT support, ive used them in the past and they are really good but finding a parting solution for this otherwise excellent little CNC lathe.

Realised earlier that I've actually got a GTN style in the lathe just now.
It's this one - https://www.shop-apt.co.uk/part-off-...2mm-shank.html
Tip to the back of the head is about 26mm. I only remembered after I'd turned the lathe off, and the parting tool was at a less than ideal angle to accurately measure.

I also measured a 26mm diameter WDN holder, and the tip to back of head is 21.1mm

Thanks. Hadnt seen your reply but APT believe it should fit so ive ordered one of these.

So I ordered this one - https://www.shop-apt.co.uk/part-off-...2mm-shank.html. Its like 2mm too long but I can grind away some of the lip that's in the way. Kudos to APT for the quick delivery as usual.
