Inductive Sensor Holder for Wilson Reprap Printer

thingiverse

I made this for my Wilson TS printer, so I'm pretty sure it will work on other Wilson models too - not that it's a huge print or anything. Go ahead and try it out for yourself! This thing is based off of mrice's servo operated stop end for auto bed leveling. It should be able to hold just about any sensor you need, but I used the LJ12A3-4-Z/BY model because it's what I had on hand. I included a photo of the wiring diagram so you can hook up your own LJ12A3-4-Z/BY if that's what you're using. Here's everything you'll need to get started: a LM7805 (which you can get from RadioShack for $1.99), some wire, and a PNP Inductive Sensor (like I used). You won't have to change any of the code in your config.h if you already had mrice's auto bed leveling installed - just update your Z_PROBE_OFFSET, which you can do right on the printer itself. If you didn't even install auto bed leveling yet, just go to Google and search for "LJ12A3-4-Z/BY 3d print" - that will take you straight to an Instructable. Note: don't bother looking at the wiring guide in the Instructable. I've got it all sorted out so your components won't get fried! Just a side note: compared to using a servo operated end stop, this thing is a total game-changer when it comes to repeatibility. If you're already using the other bed leveling system, I would highly recommend just getting a sensor and an aluminum bed. It's pretty cheap ($4 for the sensor, $20 for the bed), but trust me - it's worth it.
