Update: found a DB25 breakout board, so I was able to use the outputs on the Acorn & still have axis 4 available.

@Gary: the driver is already taken care of. I have 5 drivers for 5 motors (G540 + 1) The question pertains more to the DB25 port being internally wired to all 4 outputs on the Acorn.

@Ken... I've heard those sentiments before regarding the G540. I think Keith shares that opinion as well. The G540 ...

I am running a G540 connected via the DB25 connector, and currently running axis pairing option with 'Axis 4 paired to axis 2'.
What will it require if I still want to use my G540 and add a 4th axis? Is it even possible to do this with my current setup using the DB25 output? Or would I have to ...

@centroid467, thank you so much for your reply, that did the trick! Very grateful for your willingness to share your expertise.

Thank you for the response. I'm not sure I completely follow you though, so here is hopefully a more direct explanation of the wiring, and some additional info:

Are you using PWM from output 2 or are you using the analog 10V from H8?

I guess this question sort of confused me... I thought H8 was ...

I just hooked up my spindle for program control, but I can't figure this one aspect out. It's a BLDC motor running off a WS55-220 DC motor controller. I previously ran this manually (not controlled by Acorn or CNC12). I've mapped the PWM voltage output per the installation instructions. So the motor ...

Hey Scott, actually you hooked me up several months ago with the one that I posted, and it had been working flawlessly under 5.1 That was the one with the 3 options:
1) initial tool measurement with reference measurement
2) subsequent measurement based on previous recorded offset
3) Movable Z plate ...

So this sort of worked.. it called up mfunc44.mac but it's also throwing up a notice that it never did in the past. This worked flawlessly before the upgrade, so I'm thinking there's some variable that got changed but I haven't a clue what or where to look. When I just click the run button it brings ...

Thanks for that cncian, I shall give that a try!

I recently upgraded CNC12 from 5.1 to 5.3 and everything seems good except for button mapping of Auto Z to Plate, which previously launched mfunc44.mac. Per the instructions found in the VCP user's manual (top pic) I modified the button's xml file (bottom pic) but I get an error message stating ...
