This is a fairly simple project, but the learning curve for Fusion 360 was longer than I expected. Had the following issues, feel free to chime in.
- I set the number size at 5" but they cut at about 3 1/2. Used Arial font from Fusion 360.
- The tool path at the bottom where the frame meets the numbers was good, but not so at the top. I saw this when I did a couple dry runs but went ahead anyway. Need to be a bit more precise with the design.
- At the end of the run, the torch kept firing for what seemed like several seconds, so much so that I was concerned it would blow through the water table. Then it went into air only postflow for a few more seconds. You can see the melted area at the top of the number 8. Did I miss something in the setup?
- Water table is leaking at a couple of the corners, I’m going to try caulking first, if that doesn’t work will take off and weld the outside corners.
Oh, and I used 16 gauge sheet metal, 30 amps, 120"/min cut speed. Razorweld 45.
