Expression pedal new bottom part

thingiverse

After printing the original design, I discovered that my 10k LIN potentiometer didn't fit. I opted for a Piher PC16SH-10IP06-103A2020 potentiometer instead. I created this remix of only the bottom part since all other components remained the same as the original design. To prepare the potentiometer, I cut its shaft to 11mm. The ribs on the shaft secure the small gear in place. Assembly is straightforward: 1. Install the potentiometer, leaving the nut loose for now. 2. Attach the top and bottom parts using the gear/shaft mechanism. 3. Drill holes to secure the shaft to the top part. 4. Mount the middle double gear. 5. Move the top part all the way forward to its toe position. 6. Rotate the potentiometer fully counterclockwise. 7. Slide the small gear onto the shaft, aligning it with the larger gear without disturbing any other components. 8. Once everything is in place and functioning correctly, tighten the potentiometer nut. I use this pedal as an expression unit for my Keith McMillen Softstep 2 MIDI foot controller, which led me to employ a potentiometer value and connection configuration similar to that of Roland's EV-5. After calibrating this pedal within Softstep Advanced Editor, I achieved a MIDI value range of 8 (heel position) to 127 (toe position). To adapt it for use as the Roland EV-5: 1/4" stereo jack connects to a 10k LIN potentiometer. Tip (+5V) is linked to the white wire. Ring (output) is connected to the red wire. Sleeve (ground) is secured by the shield.
