Same as you I need to try and find information about integrating the spindle to Mach.

The called the company that I ordered all my parts from. I got a CNC controller with relays and spindle control.
There's a circuit diagram in the manual. You basically interface the board with the Grizzly's onboard VFD (Variable Frequency Drive).


I would also like to eventually add an MPG (Manual Pulse Generator) pendant -maybe a DIY. Have a 2-axis joystick controlling the x- and y-axes and a one-axis joystick controlling the z-axis. Maybe also have the rotary knobs as well.

That's a nice coolant system btw.
Saw your video too. That's a lot of coolant you're running -remind me of when I was working at my old job on a Haas.
But I do most low volume stuff, but still would like to have coolant, just not as much probably.
How do you protect your motors, electronics with so much coolant splashing around?
