I have an original printer, kinda. I play with it every 6 months or so trying one more time for a clean, crisp easy print. Still waiting. !!! I am over it. In fact I have approx 1.5 printers with several replacement and upgrade parts has meant I have a printer then some. I have stuffed up another blocked extruder/hot end E3D but apart from that it is a working printer with lots of extras. All the amendments are official, ie recommended and/or soursed from Robo3d If it interest you let me know - No idea how much it is worth to you. I reckon $5000 for all my frustration , or something less that what I paid for it new. Over to you.
