K8200 GT2 timing belt rework

thingiverse

I recently decided to rework my K8200 3D-Printer for using GT2 timing belts instead of the original T5 versions. For this I needed to design new clamps for fixing the ends of the belts to X and Y tables and I planned to do this with integrated length adjustment for belt tension. I also needed to consider the lower diameter of the 20 teeth pulleys compared with the original T5 wheels. Result were the model files included to this project upload. I originally thought I could use the original mounting brackets for the reverse rollers, but this was not correct. Unfortunately I already disassembled my printer when discovering that. Therefore I needed to mill new wheel mounts instead of printing those parts. Nevertheless I added the models of those parts to the project because it still may be printable and usable with some rework. You may ask if it was worth to spend that much time for improving the belt drives. I’m actually not completely sure. The printer runs more smoothly and the printing results look better, but only very very little. The resulting dimensions are also more accurate than before. Therefore I would say it depends if you want to achieve perfect results and if you don’t hesitate effort to get to that point.
