A friend and I have been discussing exactly how to write the G-Code to create a spiral scroll.
His rotary table 90:1 reduction with a 1600 micro-step motor could be set up to move N steps for each step of the X axis to create the spiral. But that approach seems clumsy. Say I wanted to cut a scroll with a 6mm pitch using a 3mm cutter. Without using G2 or G3 it's really just a triangle isn't it? Move rotary table distance A and move X axis distance A'. Do it in small enough increments and you get a spiral. But I feel like I'm missing something really simple. Suggestions?
