Restart is not useful, but could be

My machine got interrupted again (probably static). The gcode is 14,600 lines. I have no idea where it got interrupted. I estimate I am 6mm into an 18mm pocket. There is no search as such in CM and the Z moves are quite difficut to find by scanning. I put the nc file into chatgpt (obvs) and it said: Given your concern (“don’t want to choose a restart line beyond where it crashed”), the conservative choice is: restart at line 2453 (the -4.5mm layer).

This is very useful info and probably doesn’t need AI to get there. Why can’t CM log where the crash occurred?

Echoing: CM - Make 'Restart Program' actually useable

The standard way to do this would be to simply write the last line number executed into a file. That way on a crash you have already stored the previous line.
