I have been playing with a Laser Etching unit a buddy in Texas sent me. This is an older unit called and Emblaser I..there is a II and then two other newer ones.

I am a full on rookie with the technology and especially the PC software. I must admit, I am much more of a Mac/Aplle kinda guy than PC programmer….which is what you need for the CNC-like software. Still I am trying.

On thin plywood and cardstock I have etched out a couple images. I can certainly see this adding another dimension to my woodworking if I can get decent at programming it.

Fun stuff, hoping to use it to make a Valentine card for the wife

Is that a laser or a CNC? Title suggests laser, however, you then tallk about CNC programming.

I’m going to assume its a laser. One effective way to engrave is to do a multi pass… Your laser will determine that.. then fill with wood filler, sand and fill till all voids a filled… buff/oil/spray… and the results will be better than just engraving.

Interesting. Roughly speaking, how much does a set-up like that cost?

Yes, CNC is the acronym for Computer Numerical Control. In this particular instance it is controlling a laser, what we are most often used to seeing and referring to as a CNC machine is more accurately a CNC router since it controls a router.

For a couple hundred or less, you can get a decent one from Gearbest. You’d probably want the A3 architecture for a larger working area. A great operating software is T2 Laser. For 40 bucks, ya can’t beat it for these types of lasr machines. No programming expertise required.
Here is the machine in my shop. Though, I bought it from Gearbest…not Amazon.

Test made a cat etching for a buddy who had to put his cat down. I oil painted it up for some colour.
Plan is to make it into a leather patch for an apron I am making him

How deep can you etch with a pass? Do you have multi pass option (though it could be manually achieved)?

A good effect is to etch (with multi pass) and then wood fill and sand (and repeat till all filled… don’t try in a single pass)... gives a great result, especially if you use various wood filler contrasting colours..

You will need to engrave to about 1.5mm depth to ensure you do not bottom out on larger filled areas.

Few sample test cuts I made in different timber (the pen box was a reject)...

(I do like the Old English font…).

Yes you can adjust the # of passes, the depth of ‘cut’, the power level and the speed of pass.
You can also focus and de-focus the laser and raise or lower the laser’s height.
All of these influence the outcome of cut and appearance.
Ultimately, you can etch an internal shape and then do multiple passes around it’s border that laser cuts out the edge perfectly….I am working towards that.
