Belt Tensioner and Limit/Homing Switch Holder Eleksmaker V2

thingiverse

This design serves to secure and tension belts as well as engage limit switches. It also manages excess belt and protects the switches from impact, preventing damage. There are four limit/homing switches available: X-, +X, -Y, and +Y. I recommend using a total of four switches, with two dedicated for homing and two for limiting. Hard limit switches offer superior performance over soft limits in scenarios where position is reset or steps are lost. The EleksMaker EleksExtra external control board add-in kit can be found on Banggood at the following link: https://www.banggood.com/EleksMaker-EleksExtra-External-Control-Board-Add-XYZ-Limit-Probe-Coolant-Spindle-Functions-OnOff-Button-For-Mana-ManaSE-Stepper-Motor-Driver-Board-p-1481516.html. Required hardware includes: 12 M3 12mm long pan head screws for belt clamps 12 M3 nuts for belt clamps 4 M5 nuts for switches (the kit only provides three) 4 M5 bolts 10mm for switches, which are part of the EleksExtra kit The EleksMaker EleksExtra kit comes with three limit switches but I prefer using four. To obtain a fourth switch, an additional kit is required, as sourcing individual switches proved challenging. This design is engineered to secure nuts firmly in place. Due to varying nut sizes, some may require forceful insertion. If issues arise, heating stakes can be applied (using a soldering iron) or crazy glue can be used to secure the nuts. Alternatively, custom-sized nut capture options can be provided upon request. It's recommended that six of each component are printed: File descriptions include: BeltLimitHolder2_Main.STL - The base part BeltLimitHolder2_Top.STL - Holds the belt in place along with M3 screws and nuts Printing settings used were 0.2mm layer thickness, three layers, 15% infill, and no supports.
