Is there any way to randomise the order of the shapes burned in the material test? The localised heat effects of ramping power/frequency/speed in the x axis tend to give unreproducible results when these are taken into consideration. I have tried putting a 0% sublayer in to reduce this, but it makes the time to run a test significantly longer.
Stainless steel and Titanium especially so.
Essentially, I want the antithesis of optimise settings. Give me the biggest distance possible between material test squares!
There is not, no.
It always burns “coolest to hottest” because on diode or dsp lasers if the range is going to end up “too hot” we want it to get there last, so you can stop it as soon as a cut goes through.
Thanks. I got my galvo working with python (via meerk40t/galvoplotter). I think it’ll be a good exercise to implement this to get a good understanding of the underlying library. Will still be using lightburn for most stuff, but there are certain things that are never going to be in demand enough for lightburn to implement (see: integrating with a 20 year old robot arm!)
Implemented a (pretty gross) bit of code to brute force looking for the longest path connecting every point on an x by y grid, which I’m coining the “hourly salesman problem”, i.e. travel the longest distance possible. Let’s see if it avoids the false positives from heat soak when colour hunting on a MOPA laser.
