I have installed the latest firmware for the Ender 3 Max 4.2.2 BL, and the runout sensor does not work. If M412 S1, it will trigger even if the filament is in. It’s almost like a M600
I tested with M119 and it goes from open to TRIGGERED, but nothing happens
the firmware seems to be configured to use a smart runout sensor instead of the stock one, for some reason
I don’t have access to an Ender 3 Max - what type of filament sensor do they ship with? Or is this an aftermarket addon?
Good question… It’s not an aftermarket.
Any way I can help you with this?
In a roundabout way, I managed to find a complaint that the microswitch can cause problems - therefore its probably safe to assume that I made the error in thinking that the Ender 3 Max has a motion based sensor when it doesn’t…
I’ve disabled the option to configure it as a motion sensor, so builds from 20211003 should be pre-configured for the correct type of filament sensor…
Thats great… I will test it as soon as I can get it
Ok, back home to test the latest
We are on the correct path It will trigger a fillament change if the fillament is in the sensor
It needs to be reversed.
Ok - updated and should be set in the next build run which starts in ~20 minutes and takes about half an hour to run…
Bingo !!! It’s working perfectly
Thanks for the great support
