Ender 3 V2 Cooling Fan not turning off
I am trying to print ABS on the Ender 3 V2. The Ender 3 V2 has the option in the Controls to change the fan speed. This option appears not to be doing anything. I have check my slicer information and the fan in the gcode is set to 0%. The print will print the first 2 or 3 layer perfectly then it start to string and dry prior to being laid down. This is causing the print to be carried around the bed stuck to the hot end. I have tried 230-245C for hot end and bed temps of 70 - 90 C. the bed is perfectly level as PLA will print with the default settings.
The gives me something to try. Thank you for that. However it does not address the issue with the fan not turning off. Can you please help me with this?
The ABS hotbed is 100°, the nozzle is 230° to 240°, the hotbed needs to be open all the time;
Because of the particularity of consumables, ABS will easily crack and deform when encountering temperature fluctuations such as cold wind or humid environments. It is best to print ABS in a closed high-temperature environment;
Customers generally will use a glass box or other high-temperature resistant box to cover the machine to achieve a constant temperature and high-temperature environment.
