the following problem could be related to FreeCAD, as well as the CNC controller or the actual cnc machine. I suspect a misunderstanding on my part in the FreeCAD settings, so I try it here first.
I'm trying to mill the attached adapter plate using a simple profile operation. The material will be a 2mm carbon fiber plate, so I skeched the plate, padded it to 2mm height and created a path job. For the job's stock, I set z height to 0 on both sides. In the profile operation, I now set the start and final depth to 0, because I want to mill the plate in one go. The attached file contains all the described operations.
I now export the attached gcode file and load it into Candle. I position the bit over the cf plate so the tip touches the surface and zero the position. When I now run the operation, the bit only plunges halfway into the material and basically "engraves" it instead of cutting it. I tried to set start and final position to -0.5, hoping that this would fix the problem, but it still only went about halfway through the material.
Does anybody know why this is happening?
