9 years ago Your requests for overrides are noted and these are on the list.
The UI designer is responsible for the button that homes the machine (invokes G28.2) I suggest looking at Chilipepper.
You can zero axes independently. Please refer to the wiki for the operation of G28.2 and G28.3. https://github.com/synthetos/TinyG/wiki/Homing-and-Limits-Description-and-Operation#g282---homing-sequence-homing-cycle https://github.com/synthetos/TinyG/wiki/Homing-and-Limits-Description-and-Operation https://github.com/synthetos/TinyG/wiki/Homing-and-Limits-Setup-and-Troubleshooting
It may also be good to review the page on coordinate systems: https://github.com/synthetos/TinyG/wiki/Coordinate-Systems
May I suggest adding a feed rate and spindle speed override? Also a button to send the machine home would be nice. And why you are at it maybe a way to zero each axis separately for setting origins.
