Further to this build, here are the specs:
Firmware: Marlin 1.1.0.
Build volume: 140x140x146.
Hot End: Up to 290 degrees C. I have installed a 70 degree C fuse to the fins of the hot end.
Movement speed: up to 300 mm/s (X and Y), up to 25mm/s (Z), up to 60mm/s (Extruder).
Quality: 0.1 to 0.32 mm layers.
Materials: Mainly PLA. ABS can be used for small parts. I have yet to try Nylon.
The print quality is excellent, and I find painters blue tape is the best thing to use on the build plate.
I will probably sell the unit now, as I now have an XYZ Pro 1.0 printer.
