K2 Plus Filament runs out with CFS

Hello,

currently running a K2 Plus Combo with 4 CFS (maxed…) But since short (I guess FW 1.1.5.5 - the current) I have the problem, that if the filament runs out the continue does not work. First it cleans out (very excessive if you have 1.5m tube to the printer… g (working on that to lower times…) So far so good. Then it loads the new fil. Works. But it starts continuing the print. Turns up the nozzle to 220, goes to the print spot, prints three “steps” (didn’t watch that carefully….) then it stops and turns the nozz to 140. I can say “Warm up to 220” with the ui. But when it starts it does not take long and woops 140 again… And after a few tries it just crashes “MCU working to much” Thats I fear a job for support? Or some other solutions there?

TIA
