Double stepper extruder with hot end

thingiverse

This robust double stepper motor extruder is engineered for those who dare to push the limits of what's possible. Its purpose is to provide a lightweight, yet incredibly strong extruder with hot end that minimizes vibrations when integrated into a Delta printer or Robot Arm. The two 28BYJ mini steppers are original unipolar units that have been cleverly modified to function as bipolar motors. For a step-by-step guide on how to achieve this, please follow the link to a comprehensive tutorial: https://www.youtube.com/watch?v=ROFjf_7IrRA The body of this extruder is designed with an elastic hinge in mind, allowing for maximum part minimization. Each stepper motor has its own dedicated extruder wheel, ensuring that both motors work together to pull the filament smoothly. Weighing in at just 202 grams, the entire extruder assembly, including hot end and fan, is remarkably light. I strongly recommend beginning with a thorough reading of my instructions, treating them as invaluable lessons learned along the way. I challenge you to build one yourself and take it to the next level – make it better, and then share your creation with the world! **Print Settings** * **Printer:** Delta printer * **Rafts:** No * **Supports:** No * **Resolution:** 0.2mm * **Infill:** 50% * **Notes:** nGEN material used
