Print now failing out on start

[phoenixperry 0]

Hello! I have a problem with my Ultimaker 2 printer. when I start printing. I've done everything I can think of including: releveling the bed 3 times, checking the tension bands are not on the gears weirdly (they aren't perfectly centered but they are not grinding), reseating the motor, adjusting the filament tension every which way to Sunday (I even tried it with the tension screw removed) and printing at different settings. This is the default robot, which normally prints fine. Has anyone seen this? I'd really love any suggestions.

thanks,

Phoenix

Your printer is under extruding. This can be from either settings in cura or feeding issues.

Does it feed material fine using move material?

Try doing an Atomic Pull to clean the inside of the nozzle

How old is the printer? If you have printed 500plus hours you may need to check your PTFE coupler.

Make sure its gripping the filament properly and has clear dimples from the feeder.
