    K40 X-Axis Belt

    Posted by Ned on Jul 13th 2021

    Worked perfectly to replace the belt on my 4+ year old K40. Note the pitch on this belt is 2.032mm or 0.080in. The length of my stock belt was just over 3ft at 36-13/16" or 93.5cm. You can see here for a description on replacing the belt. https://forum.makerforums.info/t/replacing-k40-x-axis-belt/83529?u=nedman
