Confused on IR sensor MK3 to MK3S
A few months ago I upgraded my MK3 to an MK3S with MMU2S, following the guide. In this guide, and the kit I received, the filament sensor has a chimney and works like s sort of see-saw. This system does not work well. I have problems getting the sensor calibrated.
To my surprise, when I read the manual for upgrading just the MK3 to the MK3S, the sensor is completely different! It uses a ball. That's more like it. Did I miss something. What is the correct and best manual? I am confused.
The tower sensor is the correct one for MMU2S/Mk3S
mk3 to mk3s switches sensor from laser motion detection to IR+ ball
mk3 or mk3s mod to MMU2 switches to chimney and long arm tension door and moves the mk3s sensor to the chimney and removes the ball
the non-MMU setups use the sensor to enable autoload
the MMU setup uses the sensor to to tell the MMU the filament has engaged the extruder bondtech gears
That makes sense, thanks.
