I’m currently working on a model where some finely detailed parts didn’t turn out right. They’re easily removed, and I’ll solve it this time by building a new stl, printing the piece, and gluing. But I was wondering if there’s a tool out there that would have allowed me to more quickly re-gcode the portion of a piece above a given layer?
The first way I could see this happening would be for Cura or the like to allow translation of the stl down into below the print bed, with the software only gcoding the material above, or just specifying a start layer. This kind of thing would also be useful in other situations, such as printing a portion of an stl, just rotating it, then printing the other part.
The second would be a script for deleting the bottom layers of the gcode. In theory this latter would be simple (just changing the number of layers and then decrementing the Z for each layer by the Z for the first layer that should be printed), but if done manually this would be prone to error. If no such tool exists I may tinker in spare time with writing some python to do this but don’t want to reinvent the wheel.
