Thanks John, I also want to do some revamping of the 3D printer itself. It was the original <$200.00 3D printer on the market so there?are a lot of shortcomings.
Actually I am tempted to just build a new printer.
I probably have all of the components.
I have a similar printer in pieces here, a Tevo Tarantula.?
it¡¯s a Prusa clone, made with an Al extrusion frame, so good on the rigidity, but the Y-axis attachment has never worked well (actually never at all); I could never get it to attach stably to the single rail it rides on, so I spent the last few days building a dual rail rail system, using some 20x20 extrusion I had on hand.
Now I have the fun task of drilling through the acrylic heated bed support to attach the new Al stiffeners that the actual rollers ride on, hopefully without wrecking it.?
FWIW, the small eccentric nuts these things use to fine-tune the roller tension take an ¡®L¡¯ drill bit for the eccentric part. (the larger holes in the Al bars, the others are just clearance holes for a 5mm screw; a #8 works for that.?
Also note all the pictures on the website conveniently leave out the huge rats nest of wiring to the controller :-/?
Maybe I¡¯ll eventually get this thing to squeeze out some plastic. :-)
