The optical endstop is a reliable endstop / switch solution for any type of 3D printers and other CNC and/ or 3D tools. RepRap's Cartesian axes all need a datum (also known as home position or end-stop) to reference their movements. At the start of each build each axis needs to back up until the datum point is reached. For RepRap, we use one opto-switch for each axis to define its position. The opto switches also help protect the machine from moving past its intended range and damaging itself. You will need 3* (three) of these for a basic RepRap machine, and *6 (six) of them for a full machine with both home and end stops. This unit is based on the original design found here: http://www.instructables.com/id/Improved-Optical-End-Stop/ and is a improvement of Gen7 Endstop (OptoEndstop 2.1) The kit includes: 1 * optical endstop using TCST2103 Photo-interrupter 1 * connecting cable with 3 pins 80 cm length The kit does not include: - mouting screws - plastic case etc Only $17.95 - Click here to buy now! |
