Makergear X axis, carriage, extruder, y motor mount Upgrades
by Samual, published
X axis upgrade to vertical X, extruder and carriage to suit the Makergear stuff, pulleys of my own design, y motor mount upgrades... blah
So, print how you want, I designed this all in inventor to get around some failing bits, the x ends are designed for 1/4in leadscrew(I hate imperial) with 13mm lead nuts... so they may not be useful for many, also I messed up the screw to smoothrod distance, so you'll have to chock the upper mount a little to make it straight.
the extruder and carriage are paired, you'll have to support the extruder, everything else will be fine without support, this is an extension of some of my older designs, rev14 I think.
The pulleys are designed to slot together over the top of 688zz bearings, this is my own personal design and I am loath to part with it, but it is not really a patent item. I do not want to see this marketed on 'sterile' 3d printers, ie non opensource. I have successfully used different versions of these pulleys as sheaves on my sailing catamaran, serious money saver there.
The Y motor brackets are to bring the upper belt in line with the threaded rod for a 36t gt2 pulley, the other y motor bracket is to brace it back so your tensioning does not bend the first plate.
on another note, that wierd assembly on the extruder is for your belt to attach to, I tend to still use zip ties to tension my belts, never had a serious problem, my resolutions are pretty good
I am actually the major share holder in a new rapid prototyping buisness starting up in brisbane australia. we sell prints at 12c/cm^3 and $1.5/hr it takes to print it. about to build 5 of our own i3 variants to expand our capabilities
