Overview
Endstops
To implement the endstops, we are modifying the GRBL file (firmware for the Arduino AVR328P) and flashing it onto the Arduino. This process requires one to understand GRBL, pinouts of Arduino, AVR chip, AVRdude uploader. GCC is used to complile c to hexadecimal.
The source code can be found at_______________
Zeroing
The x axis (long axis) has 2 stepper motors. These are typically coupled.
For zeroing, the x axis needs to decouple - so if we get the x axis out of parallel, we can jog the x axes back into parallel by hitting the end stops.
