I've been playing with various types of 3D printers for about 6 years now, always cartesian, so time to play with a Delta.
I made the plunge and bought a Biqu Delta Pro purely for the mechanics, it was cheaper to buy the kit than buy the bits I needed separately.
As soon as I got it working I could see modifications I needed to do
The controller is perfectly functional but not 'open source' and I had a Duet on my other 'workhorse' printer. All changes to the machine can be made via G or M codes at startup or when starting a print. No need to edit, compile and download firmware
So here are the necessary files
The cooling ring is NOT my own design but I added support under the fan housing as using 'supports' filled the ring with supports too
