How to update the firmware?

The firmware upgrade for this machine is very convenient, if the machine's firmware has a major change that needs to be updated, the manufacturer will provide two files to the user, Users only need to copy these two files to the SD card, and then restart the machine. After the machine progress bar is completed, the firmware is refreshed. Then the user needs to delete the two files in the SD card before the machine is used normally. Otherwise, the firmware will be refreshed each time when started the machine.

How do I know the links to update the firmware? If SD card data is lost, how can we find it?

Please join the Alfawise U10 & U20 3D printer group in Facebook. We will release the latest firmware and the information in the SD card.

What should I do if I cannot resume printing after power shutdown?

If you suddenly lose power when you start printing parts, the machine will not save the print data. Unless we print more than 0.5mm in height, we will support the power outage recovery. If the height is less than 0.5mm, we suggest printing again.

Why the 3D printer always overheating?

Insufficient cooling;

Printing at too high of a temperature;

Printing too fast;

Try printing multiple parts at once.

 

Why the filament can't stick on the heat bed?

1. Paste high temperature adhesive tape on the heat bed or using 3D print heat bed glue.

2. The distance between the nozzle to heat bed is very important, please keep the distance is about 0.2 - 0.3mm.

Some types of filament need higher temperature of heat bed, usually PLA is 50 - 60 degree, HIPS/ABS/PC is about 80 - 105 degree.

What is the input voltage of Alfawise U20 3D Printer?

110V or 220V, you can switch the input voltage.
