Engraver alignment
« on: September 12, 2016, 08:48:51 PM »
For anyone interested. I bought the gearbest 2.5 watt laser for engraving on leather.  I haven't really had any problems with the laser or using benbox (yeah, right). But I finally got it all working. My problem was aligning my print on the leather. I played around with several ideas and came up with this. I bought 2 line lasers from Harbour Freight and since I also have a small 3d printer I printed 2 holders so I could actually have a visible line on my project. critiques and comments please. I'm going to post the stl files on tinkercad in a day or so if anyone wants. The box I did as 2 separate burns so I could look at the results.

Sounds like a great idea. Is the procedure to align the leather with the alignment beams and then jog the machine to a known position? Or do you have two laser detectors on the carriage with beam detectors and let the software find the mark?

I have the beams set for 0 y and 60 x. When I import a pic I scale it and move the center of the resized pic to center on 60. So far it seems to work.

I would be very interested in a link to the stl files for printing my own. This is a great mod and I etch on leather too.

I searched harbor freight online and didn't see the line lasers, but I'm assuming they have them. Do you remember where they had them in the store?

I like it, my CO2 has a visible laser (pointer) for alignment and it's really nice.

I used to have access to a CO2 laser at the university where I teach, but sadly no longer. So, while waiting on my Glowforge, I decided to try my hand at a cheaper diy build so I can keep etching. Of course, now I miss the laser alignment, the z-axis movement for focus, and the hex bed for easy material placement.

I came here to see what others have done for mods, and I am excited to see others in the diy community looking to improve the bare bones build.
