In development right now.
A K280 Delta printer; 600mm of print height and 280mm diameter.
Brought as a kit from China, I have used this as a base for lots of improvements:
A renkforce RF100, a very solid cartesian printer, with a good direct drive extruder.
I have been modding this printer too, it has a (220v AC) heated printbed, bigger printvolume and a decent part cooler fan now.
My 1610 CNC, another chinease kit with a few modifications; lights, fans, and a new controller card
All of the machines have Webcams
