Hello together,
i got my A20T today and the first print was OKAY but all oft the 3 extruders are warm!
than i tried a 2-Color-Prinnt and the A20T used all 3 extruders but in cura, the 2 prijects are seperated to Ex-1 and Ex-2 and than put together.

tahn i tried an other firmware.

perfect, the A20T used only the on ex BUT it runs reverse!

okay not the right firmware and i tried a nother one.

Than every moove goes in the wrong direction!

Back to the firmware before!

Can somone give me the right firmware?

or maybe the right settings in cura for printing in 2 or 3 colors?

Hi,do you mean that the motor runs in the opposite direction to the specified direction? You can try to download the firmware on the official website and upload it using the firmware toolkit to see if it works properly.

Hi William,
I do not know the right direction of the motors.

Start with standard Firmware!
I have a build a keychain.
First in black tahn in red.
2 standalone files in Cura, right click on them and set for black Ex1 and for red Ex2!
Than put the files together.

The A20T stars and all the Ex run.
On the screen: 33%, 33% and 34%!

First firmware from the internet, same file!
It starts with 100%, 0% and 0%!
BUT the extruder runs in the wrong direction!

Next firmware and the same problem as the beginning!!

I used the firmware from facebook, it is also not perfect and with glitches, but at least you can print. On the manufacturer’s website, firmware without a wheelbarrow and printing is not correct, as I see you already noticed this. I also wanted to put the factory setting, but somehow I could not find the stock firmware. There is another option to install firmware from Vert with Marlin 2.0, but I'm not selenium in Arduin and English, therefore, while I wait for the finished hex file, but for now I print on the firmware from the facebox.

Hi Vert
how much has happened here ... b&start=10

Vert, tell me where you can look at the step-by-step instructions, preferably in printed form for installing and compiling the firmware. And it’s hard for me to hear by ear how to do all this (due to my poor knowledge of the language).

thanks in advance!!!
