Eigentlich nur zwei Fragen:

  1. Woher?
  2. Wie?

It's just polite and I'm sure that nobody will judge you for "little" spelling mistakes! 😉

It's not only about tools it's also about skills! 😉

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.

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

Sorry, 4got but I am reading by 'newest' posts and forget sometimes which language 🙁

Anyhow, my questions were raised in English already in the meantime:

What?
How?

Would love to build a laser 'spindle' as well 🙂

For the moment we are just burning, not cutting although black insulation tape cuts well but still testing different materials.

Beer box card
Laminate flooring
Hardboard
Tree wood

We've not been able to burn
Polycarbonate
Aluminum

I just tried cutting through 3mm plywood and took too long.

We cut a 10 mm diameter hole at a feed of 15 mm/min on full power it took 2 mins to do 1 pass did 10 passes to get through.
