Taking notes on your projects is very important. It’s too hard to remember which material uses what speed vs what laser power. So I use Microsoft’s OneNote to keep notes on my experiments and settings for various materials.
I’ve had several people ask if I can share my notes, so here they are. It is important to remember that these are my notes to myself. These settings may not be dialed in or optimized. But it should give you a good jumping off point for your own experimentation. Enjoy!
