Files for Marlin Beta Releases GT2560 V4.0 A20M

[Ph4n70M]

Hi,

I am having some issues with my A20M with GT2560 v4.0 while upgrading Marlin 2.x :
the printer is frozen after a tool change (E0 -> E1) or using the mixing feature and requires a manual reboot.
The same firmware is working properly on GT2560 V3.1 so this bug is related to the v4.0

I've read that some users are experiencing the same issue on the A20T and noticed that a beta firmware is available from the Geeetech Github :
https://github.com/Geeetech3D/Marlin-Be ... 560%20V4.0

This firmware is only available as an hex file and I need to edit it as I'am using TMC drivers and 3D Touch as well.

Could you please share with us the beta firmware files on the repository or let us know how to fix this bug to upgrade to Marlin 2.x?

Thanks in advance for your reply

Hi，I'm sorry that it is currently unavailable, because we haven't developed with 2.x yet, we will develop 2.x in a while.
If you use 3d touch and TMC2208, you can update the official website to support the firmware of 3d touch, and then exchange the line sequence of the motor line, and there is no need to write the firmware. Our firmware source code has not been published in open source.
