Can I reverse cut with snapmarks?

[dlance1]

I have a odd shape I want to cut out from thicker material. is there a way to cut one side then turn and cut the other side using snapmarks? Any help would be appreciated.

Yes, just put a rectangular weeding jig around it. (Snapmarks aren’t actually needed, although they can be used.)

Glowforge Interface - How to Align a Double Sided Engrave

I’m going to demo an alignment process below using my (ancient) version of Adobe Illustrator, but the process is the same for Inkscape or CorelDraw or Affinity Designer. Whichever one you like to use, you’ll do the same things, with the tools in that program. (I’m also going to give you the thought process that goes into creating a design with 2D Design software, to keep from having to write another one up, so if you can slog through it, you’ll pick up some stuff you need to know to make thing…

Note: I forgot to add this part earlier…It’s also very important, depending on how thick the material is that you are cutting through, to kerf-adjust your jig so that the material fits snugly into the hole. Since you are trying to cut through excessively thick material, there is going to be a more pronounced angle on the cut profile. Also make absolutely sure that your design elements are centered in the rectangle.

I drew a long rectangle around the snap mark template. Essentially making a “snap mark ruler”. Before cutting the ruler and scoring the snap marks I taped the stock down so it wouldn’t move. After cutting and scoring I flipped the ruler over, and scored the snapmarks on the other side.

I tape the ruler to the workpiece along one edge. After cutting/ engraving I flip them both over and do the other side.
