about to start working on my repstrap Z axis and i'm still thinking of

about to start working on my repstrap Z axis and i’m still thinking of removing material instead of extruding , big question here is , are there “negative” gcode files for mendel and other repraps to use ? and more generally is there a process to “negate” a gcode file ?

regards all

It’s more complicated than that. Subtractive tools need to do things like lift to clear objects when moving between holes. You really need traditional CAM software for this. Skeinforge has some limited support for milling, but in my experience, it’s not very good.

right …well will cross that bridge when i get there , presently using Skeinforge , been testing X and Y with a marker up to now , i’m pretty satisfied with it , once i’ve got Z going good i’ll start thinking about toolhead , might also just go with an extruder for start
