I need to improve the stock holder. Currently I use 3D printer clamps, I might retry with metal clamps in the future |

Notes found on internet
- [Not Tested] Smaller passes 0.2 mm using a higher feedrate 1000-1200 mm/min
- [Not Tested] Passes of 0.7 mm using a feed rate of 420 mm/min with an RPM of 6000, plunge rate of 100 mm/min
Tips
- Be sure that the depth of your stock is the same everywhere
- Use a planer (I don’t have one and it is hard to define the 0 properly)
- Attach your stock properly
- Using double side tape
- Using super glue
- Using Clamps
- Level your bed
- let at least 10 mm around your stock to be able to clamp without touching the tool
- Don’t cut through the first time, I leave about a 1-2 mm
- Try to set your zero at the middle of the piece to avoid offset when using the edge with a small diameter
