This is a probe holder for the Carbide3D Touch probe that acts 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 cut this out of 3/4 baltic birch plywood with a 1/8" 2 flute down cut endmill, on #3 on the dewalt. Please dont trust my CAM it will probably break a few endmills.
My picture shows a flat top normally open momentary push button(https://aax-us-east.amazon-adsystem.com/x/c/QgRF8JHyCKYCQVrbDjMggpYAAAFwZa8lzQEAAAFKAdKzRhc/https://www.amazon.com/gp/product/B00XVJ9M9C/ref=ppx_yo_dt_b_asin_title_o04_s00?creativeASIN=B00XVJ9M9C&linkCode=w61&imprToken=8Ulq6KzpZdbMNf1uXsgoDA&slotNum=0&ie=UTF8&psc=1&tag=tv-auto-20" target="_blank" rel="nofollow">https://www.amazon.com/gp/product/B00XVJ9M9C/ref=ppx_yo_dt_b_asin_title_o04_s00?creativeASIN=B00XVJ9M9C&linkCode=w61&imprToken=8Ulq6KzpZdbMNf1uXsgoDA&slotNum=0&ie=UTF8&psc=1&tag=tv-auto-20">https://aax-us-east.amazon-adsystem.com/x/c/QgRF8JHyCKYCQVrbDjMggpYAAAFwZa8lzQEAAAFKAdKzRhc/https://www.amazon.com/gp/product/B00XVJ9M9C/ref=ppx_yo_dt_b_asin_title_o04_s00?creativeASIN=B00XVJ9M9C&linkCode=w61&imprToken=8Ulq6KzpZdbMNf1uXsgoDA&slotNum=0&ie=UTF8&psc=1&tag=tv-auto-20). This limits the diameter of the tool that you can probe the length of. Instead, I would recommend getting a high flush version of the same push button (https://aax-us-east.amazon-adsystem.com/x/c/QgRF8JHyCKYCQVrbDjMggpYAAAFwZa8lzQEAAAFKAdKzRhc/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=8Ulq6KzpZdbMNf1uXsgoDA&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" target="_blank" rel="nofollow">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=8Ulq6KzpZdbMNf1uXsgoDA&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">https://aax-us-east.amazon-adsystem.com/x/c/QgRF8JHyCKYCQVrbDjMggpYAAAFwZa8lzQEAAAFKAdKzRhc/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=8Ulq6KzpZdbMNf1uXsgoDA&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)
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 protruding bolt that I clamp the alligator clip to.
To verify your set up 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
If you want a 3d printed version, search on thingiverse for mine or thirdlys design
This is the second itteration of this design, the first being 3D printed and can be found here https://www.thingiverse.com/thing:4136922

Hey is there a way to export this to a Carbide Create file? I tried exporting from the Fusion file to a .dxf but it exports a design that shows the paths too? This is awesome btw! I wish I had a 3 printer to make one but I only have a shapeoko to try and cut one out. Thanks, -Shawnwdoler posted 5 years ago
So I think carbide create does better with step files. You can try exporting them from fusion360 or check out this same design on Thingiverse, I have also added a minimal version, which is my favorite. https://www.thingiverse.com/thing:4266744/filesYou must be signed in to leave a comment.
