📂 Upgrade firmware

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.

QUESTIONS & ANSWERS

Ask a Question

What is the firmware? It doesn't respond to M115, M360, M703, M20, M39, M78, M503, M450, there's no M29 T. Not knowing the firmware type makes it impossible to use A20 with Octoprint properly.

Our firmware is a self-developed closed-source firmware that is not necessarily compatible with all of Marlin's instructions (partially compatible). As for Octoprint, we have not tested whether it is perfectly compatible.
Hello, The printer print gcodes. Please what is the full list of gcodes order known by the printer on sdcard and USB (like G1, G92, M117, ...)

Bonjour, nous avons acheté une imprimante 3D Alfawise U2 pour ce Noêl, elle a très bien marché jusqu'au moment où l'on a mis le Firware (181227_U20_FW_V2.16A.zip) à jour ce matin. Constatation : Après le calibrage de l'écran au moment de l'installation, celui-ci s'affiche mais n'ai plus tactile. Nous avons changé de carte microSD même probléme. Et même si l'on réinstalle une version antérieure même problème. Que peut on faire ?

Pour les problèmes après-vente, veuillez envoyer un courrier électronique à cs@alfawise.com pour obtenir la résolution

I upgraded my alfawise u20 with the 2.14 firmware . But now it ask me to "calibrate" the touchscreen with a "clicking and adjusting" procedure. Even if I do it perfectly, it reboot and ask me again. If I dont click, it lauch the firmware but the touchscreen is not working. If I turn it on without the sd card, the touchscreen doesn't work too. I try with 2.12 and 2.10 firmware, it's the same problem. Can you Help me please?

Buonasera, vorrei sapere perché la stampante ha smesso di funzionare (ALFAWISE U-20), cioè: carico il progetto con il programma CURA 3.6, controllo che tutti i parametri siano OK, mando in stampa attraverso USB, estrusore e piano stampa a temperatura, ma …….. si ferma li non si muove per niente. Eppure quando e arrivata ha stampato tutto OK, potrei aver modificato qualche comando senza volerlo, non sono ancora molto pratico. Mi potete aiutare, grazie. PS: mi si è difettata la chiave con la micro SD è possibile averne un'altra, magari anche pagando. In attesa di una Vs risposta porgo distinti saluti

Per problemi post-vendita, si prega gentilmente di inviare una e-mail a cs@alfawise.com per ottenere la risoluzione.
