Enclosure
Generate toolpaths, following assumes 18mm plywood:
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:
- Mill support (8cm), this should leave enough room for clamps
- Mill front (30cm)
- Mill side (20cm)
- Mill top (20cm)
Cut another 40 by 80cm piece:
- Mill bottom (20cm), again this should leave enough room for clamps
- Mill back (30cm)
- Mill side (20cm)
Glue parts with wood glue (PVA). Finish with
