Denford Triac VMC with ATC Conversion / Fix

remember no touching ground with those wires, and try not to touch the copper bits.....lol

Ive taken that board out, not taking a chance with it until confirmed. Sorting home / datum switches now, a bit confusing. Home is X all the way to the left, Y all the way to the person but the datum plate is on the other side.

Is datum not home?

[Chaz]

Ok. clearly not although it uses switches called datum, that is what is confusing. The Triac usermanual confirms the same - home is correct as I have it now.

Can anyone explain why, when the CS Labs unit has a fault condition, my machine basically drives both X and Y to the positions furtherest from home? How do I stop this from happening?

Also, spindle relay wired, connected to output 6 on the CS Labs digital output but spindle doesnt run. I try M3 and M4, I can see Mach 3 flashing that there is activation, but the actual relay (24V out on output 6) doesnt kick in.

Actually, I think I know why in the first instance. I need to get enable to work via the controller. Currently the DER (Drive Enable Relay - which cuts power to the drives), is hardwired as its 0V 'on'. That said, why is something controlling it (ie, giving it reference to move), when there is a fault? Some type of failsafe?

[Chaz]

And we have life, although the motor output is being set manually at the moment and still need to sort my machine runs X Y positive when controller resets.

[Chaz]

Ok, spindle now starts on M3 code. Progress.

Not happy with the E Stop setup. Im currently using most of the original wiring but on 'reset' my X and Y still moves in the + directions. I then wired off the 24V switched to tell the CS Labs that the Emergency Stop was hit. This works but resetting is tricky.

I am going to remove the E stop setup in the current wiring mode and just wire it to the controller. Ill work another way to enable the drives.

I am basically deciding same stuff for my machine.

So i wired Estop to the servo drives not to the board. The board just enables the drives. So I hit the Estop and the drives stop instantly, they emit alarm signal that disables the board and puts all in reset condition. I reset from mach3 and board resets drives and enables them/ 2 different pins that go to relays/

What i am saying is that is ok for the board to have second circuit connected to the estop button, but its a must to stop the servos, so thats why servos usually have Estop and limit switch inputs, to react faster than boards.
