Voron Z-Belt-Syncher

thingiverse

This is a tensioner mount for adjusting belt tension with the Z-Syncher installed. Flathead screws are used so that the minimum amount of build height is lost. I used a 752mm closed loop belt(https://www.amazon.com/gp/product/B018JLCBEY/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1) and two 60 tooth pulleys (https://www.amazon.com/gp/product/B01G1N1CI8/ref=oh_aui_detailpage_o02_s01?ie=UTF8&psc=1). The bearings are the same as those used on the rest of the Voron build. Due to using 60 tooth pulleys, very little belt tension is needed to keep them from skipping teeth. V2 update: I had a problem on one of my Vorons with the Z motors "fighting" each other. I found that one side of the belt would get tight while the other side was loose. The added files and pictures are the V2 version (Print 2 arms)(Optional arms with 4mm holes if needed). I am having trouble finding small, low tension springs so I am using a Dental band to pull the 2 arms together. It takes very little tension on the belt, one dental band seems to work well. Any small, thin rubber band should work. I would prefer a spring but I am too lazy at the moment to make one. 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. The arms should move freely. Use 2 nuts on the bottom of the bolts to lock the bolt in place while allowing free movement of the arms. Add 2, 3mm bolts with the head facing down for installing a rubber band or small, light spring. How I Designed This Fusion 360
