A little question.
Has somebody added a loss recovery function?
It’s possible to modify the firmware in order to add this function?
Power loss recovery
Re: Power loss recovery
It is difficult to add this function because:
- there are several levels of buffering of data in the different MCU's
- STM32 has no storage of data
- when cnc stops, it is in an unknow position. So at least a home is requested.
Easier to add a UPS system to prevent short power off.

Re: Power loss recovery
You should write on paper X and Y from the first starting job, when power loss happen you can start again the same job at this point by: homing, going to saved X Y and set again X Y to 0. It's better to have a z-probe to set Z, but you can also save it on paper.
