K40 Adjustable Low Profile Rotary

thingiverse

A remix of the Laser Rotary Lower Profile contraption is now a reality. The motor has been relocated to the side, allowing this invention to fit snugly between the frame of my z table, where it will eventually hang proudly. I also made one of the rollers adjustable, permitting larger objects to be placed on the rotary with ease, potentially up to 70mm or so in size. A 20 tooth, 8mm bore gt2 pulley and a 20 tooth, 5mm bore pulley were used alongside a nema 17 motor with a 220 mm belt to drive the rollers. M3x12 screws are utilized on the sliders to snug them into place, cautioning against over-tightening. Sketchup files for modifications have been included. My delta steps per degree were precisely calculated at 8.888 for the cohesion3d mini configuration. This video showcases the original bases (non-adjusting), but with the motor mounted to the side, utilizing Lightburn software: https://www.youtube.com/watch?v=LFDQtm46KmQ An updated video of use with the adjustable base is also available: https://www.youtube.com/watch?v=S6A-Qc5cXDI New base options have been added, including a mirrored base option. 11/3/2018 Update: New base options have been introduced featuring lower tops to allow for some overhang of items. Additionally, one end of the driven roller has been made adjustable to accommodate tapered objects. Print 3 of the adjustable base sliders for these bases.
