Hello,
can anyone advise me on how to use the crosshairs for the template so that I can always focus the laser light on the crosshairs and start the engraving process? Thank you for your advice.
Actually, I always start off-center, and that wouldn’t work…
I’m not sure I totally follow you about what you are asking.
My machine had an led off to the side like that. Change the lens you have to change where the led points. If you’re cutting something thick, you want the focus point and the led point at different locations. Thick material needs to be center focused.
A lot of people use them, I’ve found I do just fine using a jig on the machine and not worrying about where the spot hits… mine is actually in a drawer somewhere, I think.
What I want to do is make a template with a cross on it. Then, every time I put the template into the machine, I would just need to focus the laser light on the cross and the laser would engrave correctly.
The best way to do a “re-useable” template is to use the physical boundary of the machine. Use a corner of the honeycomb to align the template each time.
If you are using cardboard as a template the absolute best option is to simply create a new template each time. It is so readily available there is not much reason you cannot afford to make a new one.
Tape a new piece to your honeycomb and simply cut the template. then it will be 100% in the correct location and there is no fiddling about trying to line up the little red dot.
You can just create a template that has the cross on it. That’s not difficult.
If you have no idea where to start, check this guide, I have an example in how to use a square as reference on a template for round objects: Coordinate systems & workpiece alignment - Diode Laser Wiki
