drew dxf drawing in LibreCAD with all dim in MM.
Loaded dxf dwg into EstlCam which was setup for all MM and for Z axis to reference top of material.
material is Styrofoam that is 18.10mm thick so I put two layers since I programmed for 3/4" material which is 19.05mm thick. So I expected cut through from the top sheet into the 2nd sheet.
I had 39.5mm of bit exposed from the tip of the bit to the edge of the collett.
I started the program and it drilled a couple of holes that I “think” were too deep.
Then it moved to cutting a large oval hole. When cutting the hole I had to hit the E-Stop.
The hole was cut a little bit at a time until it tried to go deeper and it drove the collet approximately an 1/8"into the Styrofoam. It should have stopped more than 20mm before it got to that point.
Anyone have any clues where to look? It appears that x and y are right on in there movements.
And I haven’t made any hardware mods from what I purchased with MPCNC.
