Guy Lymer created a keyring which can be used as a sample design. You can right-click and "save link as" on this link.
It's supposed to be an oval outline sized to about 60mm wide & maybe half as tall. When imported to laser cutter PC, it shows as 55mm, but we discovered that anything can be re-sized on the laser-cutter PC software, which is a good discipline anyway, as it fixes the size to something sensible.
Hinged Box
Laser Cutting procedure review
- On any PC:-
- Draw to scale in inkscape
- Surround by a box of known dimensions - for later scaling.
- Convert all objects to paths
- Save as svg (to edit later if necessary)
- Export as dxf
- It doesn't matter what you sample in, it doesn't seem to work anyway. (?)
- Put on usb-stick and move to laser-pc.
- Draw to scale in inkscape
- On laser-cutter PC:-
- File import (3rd from left top icon), & select DXF file from USB stick
- Select All, then Tools > Unite Lines with a threshold of 0.1 (note that this saves the last entry, so if someone's altered it, that needs amending)
- Set size (left side menu)
- Order cutting by colour - higher in list = earlier
- Set type (cut/score/raster) and speed/power per colour (consult tests or table in pamphlet)
- Click top timer icon to show how long it's expected to take.
- Click left side icon to 'centre to table' - often imports image outside boundaries of laser-cutter bed
- Download (bottom right of screen) > Delete all (clears buffer) > Download current
- On laser-cutter:-
- Set laser focus: Press "Z" then use focus tool (acrylic square) & Up/Down green buttons (unless someone has already set this for the material you're using).
- Esc > Datum (?)
- Esc > cursor arrows to position laser at top right of image to cut (Esc to accept start pos)
- Test to see extremes of image file. If 'Soft Stop', it's because image is outside boundaries of laser-cutter bed - in software, select 'centre to table' & lase cutter bed area should show as frame with image file inside it.
- Start to cut
