To be honest it's not going to be doing hard work its mainly going to be a bit of engraving and some pcb work mainly with the odd bit of thin cutting, so I would guess its not going to have a hard life in that respect. It's mainly to overcome the fact that 'dr engrave' while being great for the early 90's is a bit useless now and well I want to keep the machine going and this seemed a good plan.

GRBL would be good as I have a board, but I really don't know as both will do the job and it's really going to be for my hobby builds so nothing too critical as such.
