Auto Tool Setter and Shapeoko Touch Probe Holder

thingiverse

First, I have to give credit to [wdoler's](https://www.thingiverse.com/thing:4136922) probe holder and bitsetter. His project inspired me to make my own version. I liked the simple and compact look of the official Shapeoko Bitsetter so I set out to make something similar. **UPDATE:** I added a V2 to accommodate dust shoes and their holders (PWNCNC dust boot). I do most of my work with 3/4"+ thick stock and with this update a 1/16th bit works just fine without bottoming out. **UPDATE 2:** For those with a Shapeoko Standard use the "SO3 Standard" Versions. Big shout out to - [peteseyeview](https://www.thingiverse.com/peteseyeview/about) for helping with those files. **UPDATE 3:** I redesigned the touch probe holder to have tighter tolerances, use less material/print faster, and no need for supports. Still uses M4/5 screws for the bottom probe portion but I changed the alligator clip screw on the side to an M2 as well as a nut cut out. I think it would be plenty sturdy to hang on to the clip. I deleted the old touch probe files as they were inferior in every way. **UPDATE 4** I redesigned it (again) to require no supports and make it in 1 piece. No need for the lid. You will still need the touch probe holder. I created 3 files, 2 are for the Bitsetter and one is for the touch probe holder. I used the touch probe to act as a tool offset probe. It adds electrical connections from your touch probe to a momentary push button that allows you to automatically calculate tool offset. This will allow you to use the debouncing and other circuitry that is already contained within your touch probe to allow your gcode sender to automatically reset your Z-axis zero point to reflect a new bit length. I used this [High Flush Push Button](https://www.amazon.com/WerFamily-Waterproof-Momentary-Stainless-Button/dp/B012I0GSR8/ref=pd_day0_hl_60_3/145-0316177-9803705?creativeASIN=B012I0GSR8&linkCode=w61&imprToken=Tc.yXPiBtGrHevvMTn5B7g&slotNum=1&_encoding=UTF8&pd_rd_i=B012I0GSR8&pd_rd_r=cd5ddf2e-6e03-40a4-a961-ed90e21d37b0&pd_rd_w=v99LK&pd_rd_wg=rPskX&pf_rd_p=531c5da2-92c8-47a3-8df6-cb5fa8f00603&pf_rd_r=Y0P1VQ1BTD631S6TQB39&psc=1&refRID=Y0P1VQ1BTD631S6TQB39&tag=tv-auto-20) as my touch prob. I connected one wire from the push button to two bolts and washers that sit under the probe for the shapeoko. The other lead from the push button is connected to a vertical screw that I clamp the alligator clip to. To verify your setup is correct turn the power onto your Shapeoko and press the button. The green led in the touch probe should turn red indicating you have completed the circuit between the probe and the alligator clip I printed this with 15% infill and support structures for the bitsetter slit opening. I mounted the bitsetter on the front ledge of the Shapeoko and used 2 M4 screws to pin it against the ledge. I used 4 M3 screws to hold the lid in place (overkill I know), and 1 16mm M3 screw for the alligator clip mount.
