- Version 1.1 Original upload
- Version 1.2
- Removed R/C filters on limit switches. This was not working for everyone. A firmware debouncing feature was added.
- Made GPIO2 and output. Some dev modules have trouble with this as an input. Shuffled a few pins to accomodate this change.
- Version 1.2.1
- Changed orientation of relay for better layout
- Removed pull down resistor on spindle PWM circuit (it was never installed previously)
- Note: This uses the same cpu_map ans V1.2
