| Material | Usage Advised | Cut In | Feed Rate (mm/m) | End Mill Speed (krpm) | Comments |
|---|---|---|---|---|---|
| Spoolworks MatX (ASA) | Yes | See below | ~750 | 10 | Cuts well, produces a nice finish. Recommended material choice |
| PEEK | Yes | See below | ~750 | 10 | Performs beautifully |
| Spoolworks PLA | No | See below | ~750 | 10 | Melts too much when cutting, causes the cutter to gunk up and strands of plastic to be left on/around part. |
| XT-CF20 | No | See below | ~750 | 10 | Melts and causes accelerated wear to end mill |
| Luvocom 3F PET CF 9870 BK | No | See below | ~750 | 10 | Cuts well, but wears out end mills very very quickly |
| Spoolworks EDGE (PET) | No | See below | ~750 | 10 | Tends to gum up the end mill, not as bad as PLA |
The standard cut-in amounts for all materials (unless otherwise stated) is:
- Top Surfaces:
- Step down 0.3 mm
- Step over 0.5 mm
- Vertical Faces:
- Step down 0.6 mm (2 layers)
- Step over 0.2 mm
The vertical step over and top surface step down is the amount of offset you will need to apply to your model.
The vertical step down and top surface step over is the amount set in the milling toolpath
