dual extruder with magnetic actuator
This is an alternative for discarding single extrusion and re utilize the single extruder motor for dual extruder. This model is a primitive one and used rollers and magnetic actuator which uses solenoid to switch over filaments. It will use a single Pull up from the microcontroller to use magnetic actuator through a power MOSFET . G code modification is required.The motor assembly will move back and forth ,guided by the rollers and the switching of filaments will take place. This will be ideal for Horizontal X carriages. How ever the work is just started.
Actual X carriage design will be released soon. No requirement of Dual extruder Main board. Only Power Mosfet circuit for Heater and Actuator. and firmware tweak
