Thanks Angel – I didn’t think much about the color, but I’m glad I picked that one! I’ll look into adjusting the current – I still need to add the fans, right now they aren’t mounted. I’m sure it will help
Olivier, the electronics are very simple, I just put several A4988 stepper drivers on a breadboard and connected them to a raspberry pi. From there, I wrote a little piece of code to control the steppers via a web app, available at ;https://github.com/accretio/thorcontroller. Angel’s electronics are much more “professional” than mine.
