Built new version for 300 deg ut still just 260 deg

Hi.
The settings in Marlin is no problem. I was stuck with the darn screen. I don’t know what to make undone to match the original so I guess that using that tool to get read the fw that is there is the way to go here.
I didn’t know that was possible.
I do have an Octopus main board and a new screen ordered to do it myself so if it goes south I do have the same rout I intended to take as an option.
Thanks for this info, it will be fun… Or not…

Sincerely Yours
