Today my printer was ready for the first print. I started the benchy printing with petg but it prints just separated thin strings on the bed. I tried a new vacuum sealed role but same result. I tried it with new role of pla but same result. Can anyone help with this issue?

I heated the nozzle to 60°C but the Hotend cooling fan isn’t spinning at any time (nozzle temp was over 90°C). Connected to an other 24V pin the fan is running. What can i do? Thank You
