i seem to have some kind of communication problem with my ultimaker since the new cura (updateted from 12.08 to 12.12A).

this is my communication log.

i tryed upgradeing the marlin software againg but doesnt seem to make a difrence when i did.

changing the baud rate from 250000 to 115200 didnt work. swamping usb ports didnt work and neither did changing the usb cable itself for anothere one.

hopefully somebody knows what to do since im a bit at a dead end.

Right now you have selected the wrong baudrate, AUTO almost always works, try posting an error log from a AUTO session.
