Adjustable roller and endstops, Jazala-J1 3D printer

thingiverse

The rollers on the X axis had become loose allowing the print head to rock and tip causing increasingly subpar prints. This project enables the top rollers on the X axis to be kept securely tightened. One additional benefit of this modification is that the top rollers are twice as far apart providing a more stable base. The X stop needed relocation. The Z stop was replaced after it failed. Additionally, consider checking out this item: https://www.thingiverse.com/thing:3895787 as it includes a micrometer adjustment for the z axis and the other half of the z stop. I printed all parts with a layer height of 0.3mm, 20% infill, and 3 wall thicknesses. As long as the head cooling fan is operating, the roller mount remains at ambient temperature.
