A video below shows the printer in actionAll information and drawings etc are also available on my website www.andornot.co.uk, i will be writing some blogs about the build and the choice of parts over the next coming weeks whilst i researched into designing this machine.https://youtu.be/54lxImzCazISpecification: Print Technology: Fused filament fabrication (FFF) Print Media: PLA, ABS, Nylon, etc any material with extrusion   temperature up to 300C except flexible filament (new extruder and hot end platform to print such materials coming soon) Build Volume: 270 diameter x 300mm height (diameter varies depending on single or dual hot ends) Layer Resolution: 0.1 to 0.4mm Filament Diameter: 1.75mm Extrusion Speed: Travel speeds of 500mm/s and print speeds of 80-100mm/s for draft, 40mm/s for fine printing, this will be matter of your printing preference. Mechanical: Materials: Anodised aluminium, 304 stainless steel, pla printed parts Construction: Robust metal construction with some printed parts. Moving Parts: Preloaded ball raced vertical slides to eliminate any adjustment required and play. Igus rod ends and industrial bearings. Electrics: Electronics: Smoothie board 5xc, capable of dual extruders, with GLCD graphic controller AC input: 100-240VAC 50-60Hz Power Requirements: 24VDC @ 500w and 12VDC @ 15w Connectivity: USB and ethernet Special Features: Auto levelling: Aluminum heated bed with FSR levelling. Auto levelling of the bed using calibration functions built into the smoothie board Interchangeable End Effector: Interchangeable end effector, currently with a single hot end, further developments such as dual extruder, chocolate printer and ceramic printer. 12 way plug and socket for easy swap between different end effectors.
