Boxford 125 TCL - Mach3 Ports & Pins Spindle Configuration

[Reprobus]

So I refitted my old BoB and I can now jog the X and Z axis’ again

With this I decided to troubleshoot the 24v box and I have come to the conclusion that it is knackered. I’ve just ordered a replacement so I’ll hopefully have it fitted this time next week

I will leave the old BoB installed as I know it works. Providing I can get my ports & pins/set up data sorted she should run

Be interested to hear what the replacement does !
AFAIK no signal is needed from Mach3 to cause the PSU to work . It should be on from switch-on.
but without the supply to the board, the spindle relay will not cause the spindle to operate. Modern boards are happy with 12v but your old soldier BoB may need 24v.
