CR10-S4 bed leveling thumb-wheel

thingiverse

This thumb-wheel is a press fit over the existing smaller black bed leveling thumb-wheel on the CR10S, perfectly suited for use on a CR10-S4 due to its compact diameter. Seven spokes or notches on the wheel provide a clear indication of how much to turn the wheel during the leveling process. To secure the bolt in place and prevent it from turning, I remove the spring from the bolt and run an M4 nut up to the bed, utilizing a Tnut (as shown in the picture). Following this, I replace the spring over the bolt. The M4x0.7 bolt that secures the bed to the Y carriage indicates that each full turn of the thumb-wheel moves the bed up or down by 0.7mm, with one notch corresponding to a movement of 0.1mm. After leveling the bed using alternate G28 Z and G29 commands, I install a locknut under the adjuster to prevent vibrations from affecting it.
