Geeetech i3 Pro B & Pro C 8mm frame single Z motor upgrade (many tweaks, see description)
Description
Originally designed by RRacer, i have tweaked the design to better fit my 3D printer with other upgrades. The changes are listed below: - Mirrored the entire set of components so the Z motor is closer to the GT2560 board, this shortens and tidies up the wiring. - Added a mount for a 20mm cable chain that can be ran to the print carriage. - Added mount for a DB25 connector, this is used on my printer to connect all of the wiring from the print carriage to the GT2560 board (the wiring for the heater cartridge uses a seperate XT30 connector) and allows for quick removal of the cable chain and wiring. - Added holes for hotend wires to keep them secure and close the the DB25 mount (not pictured). - Changed the bearing overhangs to allow printing without supports - Mirrored the filament guide and merged with the idler support, this was done as mirroring the guide meant there was no hole to mount the guide in the frame without drilling. It has made it much more rigid as a bonus. - changed the other filament guide end to make the guide easier to print. A slot has been added for the belt to pass through. - widened the filament guide to allow my printers PTFE tube to pass through without catching it when the Z axis is near the top. - Various shuffling of slots for the frame and screw holes as they did not originally fit my frame, these might not be quite right still as my frame had the corners snap off so i cannot properly check. There are probably a few other changes i have missed but they are likely minor. You will require (copied from the original thingiverse page): 1 GT2 20t pulley for motor. 2 GT2 60t pulley with 8 mm ID for lead screws. 2 GT2 ball bearing idlers with 5 mm ID. I didn't have that, so I used ball raced pulleys. 2 T8 lead screws, 300-400 mm. 350 mm is ideal. 2-4 608 bearings (OD22/ID8/H7) 2 M5x30-35 screws 3 M3x12 screws Perhaps some other screws, nuts and washers. This has been in use on my printer for around a year now and has enabled me to achieve speeds of over 100MM/s and 250MM/s travel (along with other modifications) Included are the original files from RRacer as well as my modified ones. .SKP files are also included. If there are any questions i am happy to answer them. Feedback is appreciated. This is my first ever upload so i am bound to have missed or done something wrong.
