Rudder pedal mods

thingiverse

Many thanks to Taumelscheibe and others for all the work. Here are some extensions I have implemented. bearing_holder_2020.stl - Added break-away tabs that turn overhangs into bridges so no support material is needed when printing. - Added fillet to round the edges. 2020_endcap.stl - An endcap that works with V slot 2020 extrusions. magnet_holder.stl - Added a thin layer which converts overhangs to bridges so no support material is needed when printing. Leave this in or drill through it. MagnetGrubScrew.stl - The holes for the magnets in the magnet holder are fairly loose. This plastic grub screw fits a bit more tightly and holds the magnets in place. pedals_firmware.ino - Enhanced firmware. - Pedal values are converted to linear and use 2.56V ADC reference for greater resolution. - No pins are left floating. bearing_holder_2020.Bracket - Inspired by FastIndy's replacement for the 2040 bearing holder. - Replaces the 2040 extrusion with a 2020 extrusion. The 2040 is unneeded and more expensive. Fewer screws too. You will need to a different PCB holder as the original screws onto the bottom slot in the 2040. - Moved the bracket arms into line with the bearings as this is where the stress is. - Only 30mm high (which gave a better pedal position than a 40mm version IMHO). - Added break-away tabs that turn overhangs into bridges so no support material is needed when printing. - Added fillet to round the edges. CableClip.stl - Clip that presses into a 2020 V slot (and, hopefully, T slot) to hold wiring inside the slot. battle_pedals_pedal.stl battle_pedals_bearing_holder.stl battle_pedals_endstop.stl - Inspired by dukeroger's "battle pedals" - Much simplified design with only four parts (you also need dukeroger's battle\_pedals_-_back_cover_r2.stl to cover the hall effect sensor slot). - No print supports needed. - Two magnet holes in case you forget to mirror battle_pedals_bearing_holder.stl for the left pedal (I did!). - The endstops are small parts that are easily modified to adjust movement range. battle_pedals.step shows how the battle pedals are assembled. I used springs made of 1.8mm spring wire with 6 1/4 full turns. You will also need a 70mm long, 6mm diameter steel rod. Hold each rod in place with an M3x20mm screw. Add the endstops last. Each endstop requires 2 x square thin M3 nuts and 2 x M3x12mm screws. The magnets go into the holes in the backs of the pedals. I printed the pedal parts with PLA. Print the pedal and bearing_holder with the sloping overhangs facing the fan and with wide perimeters (I used 0.6mm). Also drop bed temperature after the first layer (I dropped from 60C to 50C) to prevent curling. Use maximum fan. Print left/right parts mirrored. If using my code, ensure the magnets are positioned to result in a voltage range of 0V to 2.5V from the hall effect sensor.
