I wrote a program that lets me cut out tuckboxes for board games. I enter the width, height, and thickness of a deck of cards, and the program writes out an .svg file that I can feed to Whisperer to cut the tuck box. I’m writing the .svg file directly, so it’s extremely clean and Whisper-compatible.
I do both cuts and scores, but scoring paper with the laser is rather tricky, because it’s hard to dial down the power low enough to not cut it, or at least not over-weaken the folding joints. I decided to try doing the score lines as dashed lines, so at least some of the paper would be intact. I wasn’t too surprised to find that Whisperer does not support the stroke-dasharray attribute, so I wrote code that chops a line into smaller lines.
I had hoped that the laser head would just cruise along in a straight line, firing the laser as it passed over each little segment, but it seemed to want to back up and make a separate pass for each of them. For x-axis lines, (left-right), that wasn’t so bad, but when it was doing y-axis lines, the laser head was still thrashing back and forth along the x-axis. It was cutting the dashed line more or less with straight vertical segments, but it was obviously slewing the laser head to the left before starting a line, then scoring the line, then slewing to the right, then back to the left to start the next one. I’m really baffled as to why it’s doing so much unnecessary head motion.
Sample SVG file is attached.
