# Enclosure
|
||
|
|
||
|
Generate toolpaths, following assumes 18mm plywood:
|
||
|
|
||
|
```bash
|
||
|
python3 enclosure.py --swap-axes --workpiece=front | tee amt-box-1-front.ngc amt-box-2-front.ngc
|
||
|
python3 enclosure.py --swap-axes --workpiece=side | tee amt-box-1-right.ngc amt-box-2-left.ngc
|
||
|
python3 enclosure.py --swap-axes --workpiece=back | tee amt-box-1-back.ngc amt-box-2-back.ngc
|
||
|
python3 enclosure.py --swap-axes --workpiece=cap | tee amt-box-1-top.ngc amt-box-1-bottom.ngc amt-box-2-top.ngc amt-box-2-bottom.ngc
|
||
|
python3 enclosure.py --swap-axes --workpiece=side --port-enable > amt-box-1-left.ngc
|
||
|
python3 enclosure.py --swap-axes --workpiece=side --port-enable --port-mirror > amt-box-2-right.ngc
|
||
|
python3 enclosure.py --workpiece=support | tee amt-box-1-support.ngc amt-box-2-support.ngc
|
||
|
```
|
||
|
|
||
|
Prepare approx 40cm by 90cm piece of plywood to accommodate following:
|
||
|
|
||
|
1. Mill support (8cm), this should leave enough room for clamps
|
||
|
2. Mill front (30cm)
|
||
|
3. Mill side (20cm)
|
||
|
4. Mill top (20cm)
|
||
|
|
||
|
Cut another 40 by 80cm piece:
|
||
|
|
||
|
5. Mill bottom (20cm), again this should leave enough room for clamps
|
||
|
6. Mill back (30cm)
|
||
|
7. Mill side (20cm)
|
||
|
|
||
|
Glue parts with wood glue (PVA).
|
||
|
