Unresponssive printer and crc errors

[Panormitis]

Hello, I have a Geeetech A10M for about a year. It was working fine. I tinkered and uploaded the firmware numerous times in the past with no problems.
However after the last firmware install, the printer became unresponsive and throws a lot of crc errors. Any ideas how to fix it?

Hi,you can try to :1.Go to the octoprint settings;

2.In the settings under Serial connection -> Behavior -> Cancel current print jobs and then execute M500 in the terminal.

and you can refer to this:https://github.com/OctoPrint/OctoPrint- ... /issues/42

I hope this can help you.

I tried other versions of firmware, I tried upgrading with and without an sd card. Didn't make any difference. I tried M502 & M500, no luck.
The screen & menus are unusable.
How many rewrites can the eeprom handle?
I'm not using octoprint

Hi, Can you upload it using the firmware that has been compiled on the official website?

Upload using firmware toolkit,
You can refer to: viewtopic.php?f=20&t=69684
You need to close the slicing software when uploading to avoid occupying the port.

I usually upgrade the firmware from Linux using Arduino IDE, with no issues so far. However when I used Windows and the firmware toolkit, the printer worked again, thanks.
I guess something went wrong with the usb drivers on Linux.

I have another problem too, I'll open a new thread for it.

Thanks for the info Vert
