Festo CNC (conversion)

Spray mist system valve installed on pneumatic line and PuzzleBox32 Mini being installed to handle VFD, valve and limit switches (Yes, I know missing limit switches on a CNC is.......)

Besides obvious functionality of movement, switching to PuzzleBox32 Mini gives me: 

1. Higher resolution (32 bit vs 8 bit Architecture)
2. Limit switches:
   1. Isolation of the limit switch from the controller board
   2. Power is supplied via the limit switch connectors
   3. Better noise resilience
3. PWM/Enable output for Spindle control (gonna be converted to 0-10V externally)
4. Aux port for mist control

I've decided to update the CNC Controller from a custom Arduino based board to the PuzzleBox32 Mini (with external drivers and external PWM spindle control). 

The PuzzleBox32 is in back order (would have been a better choice), so I'll stick with the PuzzleBox32 Mini. 

Finally done: 

1. All axis working.
2. 1.5KW Spindle and VFD installed.
3. Basic electronics (Custom CNC Controller, Stepper Drivers and PSU installed)
4. Mist cooling/air assist mounted.
5. Spoil board with thread inserts mounted.

First pieces done.

Finally, I got the time to adjust the motor mount bracket and added a belt tensioner to it. Mounted the NEMA 23 motor and added the electronics (Arduino Uno + custom shield) + driver. Tested the Y axis movement using Candle. And it FRAKKIN MOVES!!!

Got the Y Axis Stepper motor mounting plate printed in PETG and tested it. Now for testing the actual movement of the axis. 

Test setup is gonna be an Arduino, Stepper Motor driver, Power Supplies and a laptop.
