Why did my 3Doodler PRO+ stop after 30 minutes of extrusion?
The 3Doodler PRO+ automatically stops after 30 minutes of continuous extrusion, just like the 3Doodler Create+. This is a safety feature. The Screen will show "CD" for cooling down and you will have to wait 2min until the "CD" goes away on the display. Once it goes away, you can simply press the extrusion button to continue Doodling.
