Denford Software & Machines

Hi all, I was wondering if anyone knew the wiring for getting the spindle to be solely controlled by the spindle override at the front of the machine?

I know it's been done before and have seen guides but not for the board I currently have

(Photo of the board added below)

Any help would be appreciated!

It should be the bottom row of connections, there should be a 0v, 10v and wiper or signal, something along those lines. You need the slow side of the pot to 0v, the fast to 10v, the other to the mid connection/wiper.

I think one of those i posted is the same controller with the wiring

just had a look at the Starturn PC S[print controller 2.pdf,

Its the bottom 3 on the left, 10v, min, i/p
min to the low side of the pot,
10v to the high side,
I/P to the wiper

I was about to wire it when I've noticed the cable has a green one coming out of it going to AGND, which then goes into AIN2- and AIN1- too, Should I just keep this where it is or remove it?

Image added (red wire is the spindle wiper)

Blue is feed wiper which will no longer be used

Update:

I went ahead and did the wiring change, started up the machine (There is no controller board on at the moment (ontop of the Baldor board)
turned the key and tried the spindle override and nothing.. (Board does have on light on)

Anyone got any ideas? Is there something I'm missing/holding me back?

Update! It spins,

The issue was that the spin enable wire needed moving to GND then the spindle will start!

I was going to say, I don't know, but did have a feeling you needed to enable the spindle some how which would normally come from the control board. My only other suggestion would be to look at those PDFs I had uploaded a while back.

Glad you got sorted.

Afternoon,

Aware that this was one and a half years ago, but I wanted to confirm something before I start swapping wires around
The 'spin enable wire' you mention - is this the blue wire (83) from A2 of the SGR to Pin 2 of TB3 on the Baldor board?
