Why myFirst 3dPen Make heating indicator cannot be powered on?
The possible cause for this issue may be a fully depleted battery. It necessitates a charging period of at least 1 to 1.5 hours before use, and it can be operational approximately 45 minutes after achieving a full charge.
- During the charging process, the device should exhibit a flashing red and green light.
- A fast-flashing red light indicates a low battery.
- A slow-flashing red light signifies pre-heating, which typically takes around 30 seconds.
- A flashing green light indicates that the device is ready for use.
(Note: To initiate play, press the front (big) button once, and the small button at the back is used to control the filament speed.)
