Double Precision Y GT2, Printrbot Simple

thingiverse

This 300mm No Sag upgrade features double precision functionality, but be mindful of speed limitations mentioned in the MXL Double Precision source notes. Since May 2014, I've been using this on my machine, initially with 1/16 microstep configuration for optimal speed and quality. However, due to time constraints, documentation may be limited; feel free to ask questions for clarification. On July 3rd, 2014, I switched back to stock 1/16 microstep settings and achieved 100mm/s at 160 steps/mm without hitting Printrboard limits. I no longer believe a 1/4 microstep is necessary for this speed. Testing faster prints may require finer steps, but that remains untested territory. Additionally, on June 3rd, 2014, I corrected the rear clamp's incorrect orientation and re-uploaded the file.
