Hello brains trust. I'm helping my father in-law get his K1 printing again as he had issues with the hot end homing at every layer change. After some profile adjustments and a firmware update I thought it was fixed. Oh how wrong I am. I can't even get it to print, I get spammed with "filament runout, printing paused, please refill" but you see I in fact have filament loaded, it will do an extrusion cycle but still faults and carries on. I noticed in the latest update it's added all the CMS stuff in it and we don't have that with our printer, I've also tried to factory reset it and get another error message telling me I have filament when I have retracted it all and pulled it out of the sensor? ANY help at all is appreciated, I myself have Ender series printers so I'm a bit out of my knowledge pool here.
Also, I am aware I'm not on the latest firmware for whatever reason I cannot update to the latest one via USB or wifi
