The hotend is set to 180°C but it's not heating up.

Check:

- Is the printer powered properly?
- Is the printer power supply working?
- Can you move the printhead from the printers menu (this is to check the printer power supply)?
- Is the thermistor properly attached to the hotend?
- If there is a fuse for the high power rail on the printer board: is it ok?
