Why there is so much tear-out around the edges of the holes.
You can see that it took a pretty aggressive bite, which I think is This worked, but it was a very rough cut: I modelled this part:Īlthough at this stage I couldn't work out how to generate a toolpath for the square pocket around the edge, so I only ended upĬutting out the circular holes. Now that I'm clearly an expert at operating the machine, it was time to fire up FreeCAD's Path workbench and What happened, but it was basically uneventful and worked fine! This is what I ended up with: "jogging" the tool position using the buttons in the UGS interface. Once Grbl was all working correctly, I clamped a small piece of plywood to the bed, fitted a 2mm end mill and made my first cuts, manually This journey started with converting the machine to Grbl because I'm not interested in running I have bought a "6040" CNC router, and have been getting to grips with how to use it.
