I own a five tool Prusa XL, which is now working pretty well. For many people though, this 3D printer is just too expensive. In this series, we are attempting to take a StealthChanger toolchanger mod intended for the Voron 2.4, and adapt it to the Sovol SV08 Voron clone. In this episode, I adapt the sexball probe for automatic tool offset calibration, refine the umbilical setup and wire up and configure the filament runout sensors.
I think functionally, this project is now finished. The next job is to test and refine, then begin the extensive documentation that will be required. Thanks for your patience!
This printer and the additional toolheads were received free of charge from Sovol for the purposes of making this series. Everything else I’ve paid for myself.
