Z-axis belt synchronize Flsun G

thingiverse

This upgrade takes Flsun G printers to the next level. As a pre-sale owner of the printer, I can confirm that this upgrade applies equally well to all models in the G series. One significant benefit of this upgrade is that you no longer need to level your bed every time you start printing. The belt system takes care of this automatically. The two Z-axis motors remain perfectly synchronized throughout the printing process. To install this upgrade, some modifications are required on the parts you purchase. You will need access to a lathe in order to make these adjustments. When assembling the coupler, it needs to be seated inside the timing pulley in order to securely grip the motor shaft. Please refer to the drawing coupler_pulley.pdf for more information on this process. I have also included an improved rod mount with this upgrade. This is a direct replacement for the original mounts and offers enhanced performance. All parts were printed using Petg material, which provided excellent results. Here are the required parts for this upgrade: 1. Rubber belt 2GT-1000, 6mm in width Available at: https://www.aliexpress.com/item/3D-printer-belt-GT2-closed-loop-rubber-2GT-timing-belt-998-1000-1002-1004-1006-1008/32888012253.html?spm=a2g0s.9042311.0.0.27424c4d3IHrMd 2.

Collars, D3mm x D4mm x 10mm in size Available at: Search for "PV0015 Thunder Tiger" on eBay or an old rcheli website. Additionally, you will need to source bolts, nuts, and washers for assembly. Assembly Instructions: 1. Mount all parts according to the upgrade specifications. 2. Home your printer, level the bed, leave the motors on, mount the belt, adjust the belt tension on both sides. 3. If one side is not properly aligned, the motors may lose torque. Once you get it right, printing will work smoothly without any issues. Happy printing!
