Voron Z-Belt-Syncher

thingiverse

This is a tensioner mount for adjusting belt tension when using the Z-Syncher. Flathead screws are used to minimize build height loss. A 752mm closed loop belt and two 60 tooth pulleys were utilized. The bearings used match those found on the rest of the Voron build. With 60 tooth pulleys, minimal belt tension is required to prevent teeth from skipping. V2 update: On one of my Vorons, I encountered an issue where the Z motors would "fight" each other. One side of the belt became tight while the other was loose. The added files and pictures are for the V2 version (Print 2 arms), which includes optional arms with 4mm holes if needed. Due to difficulty finding small, low tension springs, a Dental band is used to pull the 2 arms together. It requires minimal belt tension, and one dental band seems sufficient. Any small, thin rubber band should work. Print Settings: Printer: Voron 1.5 Rafts: No Supports: No Resolution: 0.2mm Infill: 100% Notes: V2 instructions: Print one plate and 2 arms. Use 4mm bolts for mounting the arms to the plate, ensuring they move freely. Apply two nuts on the bottom of the bolts to lock them in place while allowing arm movement. Install two 3mm bolts with their heads facing down for attaching a rubber band or small spring. I designed this project using Fusion 360.
