CR-10 X AXIS BELT TENSIONER

thingiverse

This is a simple x-axis belt tensioner, utilizing a basic cam design mounted to the x extrusion via an extra m4 t-nut and one of the additional m4 screws provided with the cr-10. This setup significantly eases the process of tightening the x-axis belt. First, loosen the x-axis pulley assembly slightly. Install the tensioner at one of its lower settings. Then, gently but firmly pull on the x-axis pulley assembly and start advancing the tensioner cam until you achieve the optimal belt tension. You'll reach a point where the cam cannot be advanced to the next notch, indicating that it has reached maximum tension. At this stage, simply tighten the pulley assembly, and you're done. The tensioner assembly can now be removed. The purpose of this tool is to facilitate the tensioning process, not to remain attached to the extrusion. Leaving it on could result in your extruder colliding with the assembly at around 270mm or higher if printing models larger than that. However, this isn't a concern for smaller prints. It's up to you to decide how best to proceed.
