As title, what i must add to say at marlin that 0,0,0 is where i start g29?

Nobody have mesh bed leveling? How do to cut big vinyl or stencil without it? I mean we are talking about 200micron for stencil an all the bed, i think it’s almost impossible do it only calibring the machina manually…
I don’t know about the vinyl knife, but with the pen mount there is a bit of flex built in that holds some downward pressure on the pen, which allows it to follow the contour even if the work surface isn’t perfectly level. For my router work I used a surfacing bit to flatten my spoil board.
