When running a job straight from the SD card, there’s an elapsed time displayed on the LCD, however as soon as the job ends, that time gets reset and disappears. I like to keep track of how long a job takes however I’m not always at the machine when the job ends. Is there a way to keep that time displayed and only reset it when the next job starts, and/or till I trigger a homing command?
no sorry. if you can program you could try to change it 
Hah! Ok. Won’t promise anything as I already have several other projects going on, but I’ll grab the source and start poking.
