Here's some GCode for 3/8" clamps. Review these and edit as necessary. I have not run these so verify before use.

So would that laser be powerful enough to do acrylic engraving? Been thinking about a laser engraver, but if that works....why do anything separate?

My laser diode is a blue 445 nm which makes it color dependent as in power absorption. If the acrylic were red and/or possibly opaque it might. I think you would have to try down towards 10640 nm range to work with clear acrylic. The power may be enough, I am not sure. I have run mine around 1/2 to 1 watt but I haven't done much experimenting yet. Drought=golf!

You should be able to mark acrylic with the standard paper backing.

I would want to engrave the rowmark laser engravable plastic - black with white engraving.

I did a lot of work with New Hermes equipment over the last 40 years and would suggest getting an engraving bit if you are using engravoply type material. Good Day.

Built this off the DW660 dust shoe design. Shortened by 20mm to gain back some Y axis. My particular rig loses Z axis due to the mounting. It works really well though. I'll try another with 1/4" acrylic to see if that helps.
