Hi SandervG,
Thanks for your quick reply.
No material station, it's just a standalone S5.
I've cleaned both print core pcb's, although I assume these are independent of each other and unlikely to both fail at the same time.
If I change the filament t extrudes correctly. If I remove the bowden tube I can feed it manually. I can feed it through the controls on the front and it extrudes. As soon as I try and print something it stops extruding and grinds the filament.
It comes up to temp quick enough, about the rate you suggested above. It seems to hold this during printing and I assume the displayed value is measured not calculated so this should suggest the temperature is correct.
It feels like a temperature problem, especially as a couple of times now it failed to reach temperature for a hot pull, but I can't pin it down.
Thanks for your help

Hi, thank you for your post.
Do you also have a material station?
You could inspect of the small pcb on the back of the print cores are still intact, and clean? You can try to clean the contact points with a cotton swab and some alcohol.
Nothing has changed in the firmware for an Ultimaker S5 stand alone that could be related to this, as far as I know.
If you set a temperature (like 220ºC) on your print core via the menu on your Ultimaker S5, does it reach it? It should increase by like 5ºC a second or so.
