IR Sensor sensitivity on I3MKS3 MMU3S
The IR sensitivity sucks.
When I change from PLA/PETG to fila-flex or nylon I have to fine tune the gear pressure in the head by hand.
There are some improved chimney designs out there to increase or let better adjust the IR sensitivity.
But is there any experiance with this mods for printing a wide range of materials, without fiddling?
IMHO messuring the gap between two gears by a bar going through an IR is a bit old fashioned. I like such low tech approaches, if they are a solution to the problem. Is there no better way to meassure the distance?
Any help appreciated
