How to Solve A8 or A8 Plus 3D Printer Nozzle Heating Issues
When using Anet A8 or A8 Plus 3D printer, the nozzle sometimes doesn’t heat up well. Why is this happening and how can we solve it? Let’s go through below paragraphs and learn about Anet A8 series 3D printer nozzle heating procedures.
The nozzle of Anet A8 or A8 Plus 3D printer is heated by a heating tube which connects to the mainboard. There is a D8 indicator, which is also known as heating tube indicator. We can observe the D8 indicator while heating up the nozzle and find solutions for nozzle heating issues quickly.
D8 indicator for nozzle heating on the mainboard for A8 or A8 Plus 3D printer
Generally, when the D8 indicator lights up, the mainboard starts to output electricity to the heating tube and the heating tube starts to heat up the nozzle.
- If the A8 or A8 Plus 3D printer is just connected to power supply and the D8 indicator lights up immediately, then the mainboard is already damaged; replace the mainboard with a new one.
- Click on “Preheat” and select nozzle heat-up option, and the D8 indicator lights up normally, then the mainboard works well; if the D8 doesn’t light up, replace the mainboard with a new one; If the D8 indicator lights up but the heating tube doesn’t heat up, replace the heating tube with a new one.
That’s all the procedures to check out and solve the nozzle heating issues for Anet A8 or A8 Plus 3D printer by observing the D8 indicator; also these methods work for the A2, A12 and A16 3D printer.
