Prusa i3 Raised Y-axis Belt

thingiverse

I wanted to maximize the space under the Y-carriage without reducing print bed height or printer footprint. I decided to relocate the stepper motor and adjust the belt plane to eliminate a dangerous setup that put wiring too close to the pulley and drive belt on my Y-axis. To retain print bed height, I replaced the original bearing setup in the new idler with a better design and made several key modifications. The new idler required 2x M3 washers (6mm OD) instead of one for optimal function, but still works perfectly without bearings. Moving the stepper motor outside my frame required longer GT2 belts than I initially used. Mine turned out to be about 900mm long and has since then functioned very smoothly. However, reversing or changing the direction in firmware can't just be left undone if the belt mount was moved across by flipping the original stepper. Several upgrades took place to fix a major space shortage that existed prior on my Y-carriage system including swapping the bearing with the flanged bearings. In all truth though, swapping and installing these simple upgrades brought massive results with print area more than doubling after doing so! In terms of specifics - rear now takes 160mm by 120mm dimensions x a height of forty mm which isn't that bad to fit right next to it the back area can actually take measurements as wide as 240mm with depth going up forty also
