Laser nozzle air extension

Post by Martin Kloft » Thu Dec 29, 2016 3:16 am

To remove the smoke when cutting mdf, 3d printed an extension for the nozzle
By opening the air inlet hole to the top the extension can easily be installed/removed.
The distance to the cutting area is reduce to about 2 mm.
Cutting speed improved from 10 to 15 mm/sec (3mm mdf , 75% power (18 mA)

If the ring above your new nozzle is a mount for the laser pointer off to the left in the photo, consider what happens if you add a bracket for a second laser, ninety degrees to the first and change from dot to line. When properly adjusted, the cross of the two lasers are always on the burn point. I printed one, but over-tightened the setscrews and split the mount. It was great while it lasted.
