Belt Tensioner and Limit/Homing Switch Holder V-Slot Eleksmaker

thingiverse

This is used to hold and tension the belts as well as hold the limit switches. There are 4 limit switches -X, +X, -Y, +Y. The Y limit switches are expected to be installed in near left and rear right. This design also ensures the limit switches cannot be crashed into and cannot be damaged. This design also manages excess belt. Requires these limit switches Search Ebay “6x Mechanical Endstop Limit Switch CNC 3D Printer” Qty 12 - M3 12mm long pan head screws (for belt clamp) Qty 8 - M3 8mm long pan head screws (for switches) Qty 20 M3 nuts Designed to hold nuts tightly. Some nuts are different sizes. They are intended to be pressed in with a little force. If you have an issue you can heat stake (using soldering iron) or crazy glue nuts in position. I can also provide different size nut capture options if requested. BeltLimitHolder.STL- Contains a full set If you want to print individually, here's the file description X_AXIS-BeltLimitHolders.STL- Contains only the X Axis Limit and Belt Holders Y-AXIS-BeltHolder.STL- Contains only the Y Axis Belt Holders (no Limits on these) Y-AXIS-BeltLimitHolder.STL- Contains only the Y Axis Limit and Belt Holders I printed with 0.2mm layer thickness, 3 layers, 15%infill, no supports. Do not connect all 3 wires while both NC and NO legs of the switch are connected to the PCB. When using more than 1 switch in parallel (which is common setup), you'll create a short circuit and you'll damage your controller. For instance it's recommended to use NO config, then clip the NC leads of the switches. Then connect min and max X in parallel. Also connect wires for min and max Y in parallel. Clip the NC leads for all switches!!!
