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

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.

an absolut good reference ->


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

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.

Our updated laser attachment:

We have found the laser doesn't need mounting quite as high but still require the pole for the wire route.

so many pictures but no clear info how we connect a j tech laser to a stepcraft...
can anyone detail ?

Can we rely on on off switch of the laser providing we use estlcam for cut program creation (or engraving program) ?

Thanks.

blanthegenius.. would it be possible to tell us more on how to output a signal for only on/off of the laser connected to relay 1+ gnd wire.... ?

I mean I only have WinNC-PC and estlcam.
Could need some help to understand the commands that make relay1 on/off ?

I'm using the J Tech Photonics 2.8W laser. This requires an external TTL signal on/off for start stop of laser.
Pobably your connection relay1(wire 13) + gnd (wire2 ).. will do the trick but using what commands in the G-codes.

for a different fast holder i made a 3d-printed holder for the J tech laser.
Please see my project here :

J tech stepcraft project link of 3d model

Thanks.

He already told that in this thread.

He used Relay1 pin and GND for on/off. In your control software, configure M03 to actuate over Relay1 pin.

To get the gcode, he modified the postprocessor so a negative Z means laser ON and a positive Z means laser OFF.

This part of the code did the trick:

    +---------------------------------------------------
    + Commands output for Plunge Moves
    +---------------------------------------------------
    begin PLUNGE_MOVE
    "[N][S]M03"

    +---------------------------------------------------
    + Commands output for Retract Moves
    +---------------------------------------------------
    begin RETRACT_MOVE
    "[N][S]M05"
