Servo Controlled Blast Gate + AC sensor

<p> <figure class="media"> <oembed url="https://youtu.be/kXWEuUqU3tQ"></oembed> </figure> </p> <p>I printed gears and mount in ABS and it seems to work fine. I printed a second set with the gears made from armadillo filament. Time will tell if there is any real world difference.</p> <p>Travel will cover a 4 inch blast gate and all three pieces will print on a single 200x200 bed.</p> <p>For smaller gates, you can trim off the end of the geared rack.</p> <p>You will probably want to lubricate the gears/slider mechanism.</p> <p>For servos, you need something with some torque. I used these: <a href="https://www.aliexpress.com/item/1-pieces-MG946R-upgrade-RC-Metal-Gear-Torque-Servo-For-Boat-CAR-13KG-Torque-Metal-Servo/32854187745.html?spm=a2g0s.9042311.0.0.3da24c4d3N29DO">https://www.aliexpress.com/item/1-pieces-MG946R-upgrade-RC-Metal-Gear-Torque-Servo-For-Boat-CAR-13KG-Torque-Metal-Servo/32854187745.html?spm=a2g0s.9042311.0.0.3da24c4d3N29DO</a></p> <p>I like them a lot.. metal gears and screw hole.. just mount the horn that matches the indentation on the wheel and use a longer bolt to mount it.</p> <p>It's running powered off an arduino uno running from a 7 volt power supply. Don't try to power these servos from a 5 volt USB.</p> <p>If you want these to automatically open when power is detected on your tool you will want the sensors and my case for them from here: <a href="https://www.thingiverse.com/thing:3368330">https://www.thingiverse.com/thing:3368330</a></p> <p>See Arduino source code here: <a href="https://github.com/Tailslide/BlastGateServo">https://github.com/Tailslide/BlastGateServo</a></p> <p>I don't have a wiring diagram but if you google wiring buttons and leds to an arduino there should be some good examples.</p> <h3>Print Settings</h3> <p><strong>Printer:</strong></p> <p>FLSUN i3</p> <p class="detail-setting rafts"><strong>Rafts: </strong> <div><p>No</p></div> <p><strong>Supports:</strong></p> <p>Yes</p> <p class="detail-setting resolution"><strong>Resolution: </strong> <div><p>0.25mm</p></div> <p><strong>Infill:</strong></p> <p>55%</p> </p></p> Category: Machine Tools
