Beginner on Geeetech A20

[Briaeros]

Hi to all,

I'm a beginner with my Geeetech A20.
On the signature, I've reported the information from the printer, and I'm searching if I have to update the firmware.

But anywehere I go, I find a lot of post where is reported "for the Geeetech A20 the firmware is here"
When I'm on page to download the firmware.... I don't find any file, or link or other with the word "A20" , or "Geeetech A20"

Could some one help me?
Thanks!

Hello, downloading the firmware is very simple, just log in to the geeetech official website:

Hi Admin,

first of all, sorry for my english, because most probably I was uncler on my request.

I confirm that I'm pretty sure that from page you sent me, I have to download the version:
A20_G05(GT2560V4+CH340) V1.1.8_14 ? 2020-01-08 365 KB

To complete my question it's related to "what it's the procedure to follow to update the firmware".

As reported even if I'm searching inside the Forum, I'm in difficult to find the correct procedure that describe the steps for A20 only.

My prudence on be sure for the procedure, it's because I'm very beginner on this "hardware", and I've doubt that if I'm doing the wrong steps... I have to sent to trash the printer...

Please be patient
Thanks for your time!

Hi Admin,

I'll try to follow some steps.

Board index -> 3D Printer -> Geeetech A20 Series -> Geeetech A20
The only link that seems useful it's the last one: Firmware for geeetech 3D printers
Other links are for A30, E180/D200 ... for me as per beginner... I'm inside of forum about A20, I don't understand why are reported others model... YES. I'm a begineer.

Go ahead with "Firmware for geeetech 3D printers". There are 2 informations:

Note: if you don't know how to install the firmware, come here: 1. For board GT2560 and sanguinololu:

4.Geeetech A20 with LCD12864
A20_Marlin-1.1.x12864.zip

Question for point 2] : Is this the correct firmware for my A20?
Because this file is "A20_Marlin-1.1.x12864"...
but looking on before post, I've to download... A20_G05(GT2560V4+CH340) V1.1.8_14 ? 2020-01-08 365 KB



Question for point 1]:
I understood that for A20 I have to use Arduino 1.8.5 to finish the upload.
Donwloaded, installed, easy.

Then, I'm following the video https://www.youtube.com/watch?v=o1QKSgnk_ig name "Geeetech A20M upload the firmware guide" (NOT A20), but the video is made for Prusa_I3, and during the video, will be required to use the U8glib.
But the U8glib are not inside the A20_Marlin-1.1.x12864.zip downloaded on point 2]

I have to proceed withoud the U8glib? If I make an error uploading the wrong firmware, I have just to rewrite, or I've lost the mainboard?

Ho hope that I will be more cleare on my doubts.

Cheers.
