    Hello,
    My filament is Amazon basics PLA.
    Hotend is 215 degrees bed is 60 degrees, Retraction is 1.6mm. I am printing through octoprint.
    Board is Skr mini 1.3 with Marlin. All required changes has been done in firmware. It was printing flawlessly. with this settings in the past.
    For a couple of weeks I am getting under extrusion after first few layers. nothing has changed. I have disassembled the unit,cleaned all pieces, changed the nozzle, tested extrusion it all looks fine. When I cancel the print after under extrusion, next time when I do a test for extrusion, it extrudes properly. until the print starts.
    Again after few layers no extrusion. I suspect it might be the cable. so I have ordered some new cables. but do you have other suggestions.
    I also checked the gears for cracks and I have tried all tensioner versions.
    Thanks.
    Cem
