My CDC 3D printer (dual extruder) has a problem about 15 min into the print. The extruder seems to work normally when the print is starting but stops outputing plastic after 15 min enough time to put the print base on the platform. I tried multiple prints and the problem is the same. The temperature report seems to be normal but nothing flows onto the print and the nozzle gets higher with nothing printing. Please help with this issue if you have a similar experience nor not.
