Eleksmaker Rotary Conversion

thingiverse

I wanted to convert my EleksMaker rotary into an engraver capable of handling narrow cylinders. After purchasing the EleksRotate rotary, I decided to try engraving on my turned pens but realized the rollers were spaced too far apart for a pen. Instead of suspending my pens between two large disks and dealing with complex calculations, I opted to create new end plates to reposition the rollers closer together. This approach would maintain the 1:1 ratio, requiring only adjustments for the circumference of my pen. To achieve this, I moved the rollers to the bottom of the plates, eliminating the need to raise my laser for proper focus. The bearings are a tight fit and will require some force to insert; I used a small bar clamp but a vice with soft jaws would also work. The stepper motor mount is adjustable to maintain proper tension on the belt, ensuring smooth operation. Assembly is straightforward, using only parts from the original EleksRotate kit. I've included SVG files for those who prefer to laser cut instead of printing; 5mm material is recommended for this process. Please note that my prototype pictures show the rollers slightly closer together and lower to improve belt engagement on the pulley closest to the motor. V2 has been added by request, featuring additional positions for mounting rods. However, this may cause clearance issues with the stepper motor and remains untested.
