Original design from :

Aim of this remix :
- Make a version for motor XC60PG60S
- Make a better locking system
- Increase the space in cab
- Decrease the small gear size (supposed to make guidance settings more easy to find and accurate)

Design to reach it :
- Spring loaded "emergency stop"
- Rod channel
- Endstop cut in the STR column support
- Motor support 15mm longer
- 12 tooth small gear (original is 19)
The big gear is unchanged!

Materials :
- all printed parts
- drilled plate with 4x M5 nuts welded (see video https://youtu.be/I0TzMpkRy_k )
- 4X
