Questions? Announcements. Support. https://www.facebook.com/groups/679001895990790 This design is part of my bigger project Custom built CR10 https://www.thingiverse.com/thing:4333962 and I decided to part of this project publish independently as it can help maybe someone other and this way is the main project more structured and transparent. #####WHAT Simple belt drive for the usual rail bed system used in CR10 S4 ( or S5). Motor bracket and belt tensioner. Not expanded over printer base frame. #####WHY It was needed for my project and the existing systems didn't fit my expectations. It is more massive to be able in the future run bigger pulleys. #####HOW It is not a common one-screw belt tensioner but it is obvious from pictures. Already tested. Tensioning process: slightly loose main M5 screw, tight two M4 screws, and tight main M5 screw again. #####BOM (motor, pulley,belt, idler and M4 drop-in T-nuts) screws M3x10 4pc M4x10 4pc M4x12 5pc M4x45 2pc M5x50 1pc nuts M4 2pc M5 1pc M4 drop-in T nuts 9pc https://www.youtube.com/watch?v=YGN5xJmQ-tg
