Free Robots & Mechs STL Download - Pan & Tilt w/NEMA17 Steppersby SMT_M 🦊

Latest update: 05AUG2019 Work in progress! This is a Pan and Tilt mechanism driven with NEMA17 stepper motors. This design is a modification of the design by thingiverse user 'buffcleb' at https://www.thingiverse.com/thing:1396552 ***** (Current Rant): MakerBot needs to get their spit together and fix the Thingiverse website. If it keeps screwing up like it has been doing, it will ultimately fail and people will find a new venue. Are you listening MakerBot? Probably not. They make crappy printers, too. ***** (Latest Update): Added buzzer to make beep when key is pressed. Buzzer is the type that makes a tone by just applying voltage. I connected the (+) lead to pin 10 of the Pro Micro and the (-) lead to ground. I updated the .ino file to use the beeper. ***** (Update): Replaced the file FrameSpacer.stl with new version that adds some clearance between the belt and this part by removing material from the 3 screw guides at the curved end. ***** (Update): Uploaded schematic and sketch files for control using Arduino Pro Micro with A4988 stepper drivers, I2C 8-port adapter, 4x4 keypad, and 20x4 LCD. ***** (Update): Uploaded Arduino sketch. The .ino sketch file is working, but is constantly being refined. It isn't necessarily pretty, but it works, and pretty much eliminates possibilities of erroneous entries (except for the A, B and C keys, which are so far not implemented). I will be modifying this program in the future to clean it up and add features. The input routine was dashed together due to my lack of experience programming with C type languages. So, the program first prompts to enter a speed value from 1 to 999. A speed of 1 will pan (and/or tilt) at a rate of 1 degree in about 16 seconds. A speed of 800 moves 90 degrees in 2 seconds. Entering 0 or just pressing the star key at the "Enter speed" prompt will set the speed to 800, and pressing the star key at the pan and tilt prompts also enters a 0, which makes it easy and fast to return both axes to the home poin
