VORON 2.4r2/2.4/2.2/2.1 Z1 preloaded rails kit

All orders of that kit in destination to the USA are DDP, meaning no custom fee at arrival!!

This kit allows you to swap to quality Black Z1 preloaded rails for your VORON 2.4

This kit mirror the HIWIN version of this kit on the store, with a more attractive price compared to Hiwin. Quality is top, tested at BRS since years, and offer a better price/value for smaller budget.

Context:

Linear guide preload eliminates the clearance between the carriage and the rail  Manufacturers achieve this by using specific sized ball bearings.

By eliminating the clearance, it increases rigidity and reduces deflection when external loads are applied. In a 3D printer, rails preload is a key factor to increase precision and improve the input shaper specs since no preload are cheaper, but get some play, more sensible to vibration across our high accelearions values..

The ball bearings used to achieve preload are slightly larger than the distance between the raceways of the linear guide and the rail. Common preload amounts are between 2 and 8 percent.

Most commonly used cheap rails are Z0 (No specific preload)

Choosing the right pack:

1- Choose the machine size
