4040 VSlot Nema17 Nema23 linear actuator
Description
These mounts allow for a stepper to be mounted to vslot 4040 to make a linear actuator. Inside the 4040 is an Igus 1/4" high helix lead screw, with their square flange nut. The nut fits inside an 18mm aluminum tube with an ID of 12mm. The inline version is easier and cheaper to build than the pulley version, but obviously depends on a plastic motor mount. The nema17 mount has been run for a few hours, but the nema23 has only been assembled, not run yet. The igus screw and nut runs around $35. Add about $15 for the vslot and bearings. The line video will be uploaded soon. Video of the pulley version: https://youtu.be/fm0g7oYxJB0
