....I can attribute that to my temperamental printer though.
Hey Bryan, I know we both jumped into the MakerFarm Prusa i3 at about the same time. I've made a series of upgrades since I got mine, most recently changing over from smooth rod to V-Rail for the Y-Axis, with the x and z soon to come. HUGE improvement! I bought bulk rail and other parts from openbuildspartstore.com and laid out my on conversion, but MakerFarm does also offer a conversion kit if you're less adventurouse... either way, the printer works MUCH smoother on V-Rails than on the rods.... trust me, tried linear bearings, pillow block bearings, v-rails is the way to go....
I also dropped the J-head (with problematic PFTE lining) in favor of the E3D hotend, and most recently the E3D Volcano that can melt plastic even faster...
I've got a custom V-Rail i-3 clone shaping up now built on all the experience I had making this early MakerFarm i3 do what I want it to... It was getting to where more parts on the printer were of my design than what came with the kit, so I decided it was time to put all my mods together into a design of my own. OpenBuild has all the stuff for that sort of thing....
