Thank you both kbOnly and Mellbreak for sharing your progress. I also wanted to use more of the Mach3 controls for my 3040Z-DQ machine.
Mellbreak, would you mind sharing your source for the connector and plugs? I'll see if I can cross reference to Mouser or DigKey here in the US.

Hi Louie,

All the connectors are standard JST parts from eBay....


For example:

Mini Micro 1 25mm T 1 4 Pin JST Connector with Wire x 10 Sets | eBay

and

If there's anything else I can help with, shout up.

Thanks for the connector info Bob. Was able to locate locally at Mouser. (catalog page)
I happened to find an unused one in an old computer in the mean time but my main controller is a little different from the 3020, the spindle controller is the same though.

Now I have to trace the signalling on the controller. Which control on Mach3 can I use to turn the spindle ON/OFF without running a program?

Louie,

Have a look at post 1 of this thread by kbOnly. You'll find the information you need there along with a circuit diagram of the spindle controller on-off circuit - at least the bits that you need. You'll need to pick up the Mach3 spindle on/off signal from pin 1 of the parallel port and +5V form your MAIN controller board (i.e. NOT the spindle controller). If you need further clarification, please ask and I'll try to help.

What equipment are you running Louie and does it already have PWM control?
