Laser engraving - Star Wars Stormtrooper
Stepcraft 420
2W m140 445nm blue laser diode

Laser engraving? Interesting! I'm looking forward to read more about the setup. :woohoo:

Is this an kaleCNC Laser ?

anyways... you should think about an external exhaust system. the fumes are toxic...

hi,

usually the laser optic should be as short as possible above the material to improve the focus.

an absolut good reference ->

i can truly recommend this! (basicly this is one cause of more in and outputs i need 🙂 )

you can also find videos about building the lasershoe II on his channel!

PLEASE NOTE I WILL NOT BE HELD RESPONSIBLE FOR ANY DAMAGES INCURRED, TO SOFTWARE, HARDWARE, SAFETY WEAR, OR PERSONAL INJURY, FROM ANY MODIFICATIONS MADE IN RELATION TO THIS INFORMATION, AS USING A LASER DEVICE IS DANGEROUS.

Ok I'm a complete novice when it comes to laser cncing, here's how I've set it up.

Any hints and tips will be much appreciated thanks.

Safety Glasses: Uvex S1933X Skyper Safety...e Uv Extreme Anti-Fog Lens
Tested on the Laser Pointer Forum Click here

Power supply: An old CB radio Power Supply 13 volts max at 3 amps

Laser driver: Click here

Laser diode: Click here

Connection: Dsub 15 pin 2 row male

Connection / Software:
The Dsub connector from TTL on the controller goes to ground pin and relay 1 pin
(ref to this can also be found in the Operating instructions manual on page 15/16).

If you are using vCarvePro v6+ you can modify the post processor file
(help files can be found on the vectric website).
We modified it so that Z plunge is a M03 which starts spindle and Z retract M05 is stop spindle also remove any reference to [Z].

This is in metric [1.3] G21 G71
in inches it is [1.4] G20 G70
