Bot Pimping again
I printed out and installed TwoTimes’s Lowrider upgrade for Big Red. Files are here: http://www.thingiverse.com/thing:4213
It uses the original belts and rods, but replaces the rest of the X and Y stages with printed parts, plus small bearings in place of the nylon linear bushings.
Result: lower motor power needed, smoother operation, markedly less bot noise, and the platform sits about 1 cm lower. Also the Y rails are farther apart for more stability.
I don’t have endstops so that wasn’t an issue, but I do need to drill a hole at the right front and rear corners so that I can use small cable ties to secure the heated platform wiring and the Y motor cable.
In related news, I have officially put my other Cupcake “Baby Blue” into Splatspace. I am training folks to use it and it will be the Space’s printer for the forseeable.
I have two members interested in building Mantis mills so I should be starting to post build videos soon.
