UM3E send gcode error

Recommended Posts

Posted (edited) · UM3E send gcode error

For ultimaker 3 extended, I upgraded the firmware to the latest version and then set the ip address of it as static. Then I tried to use ssh to send G-Code.

It works perfectly for: 

ssh ultimaker@ip

password ultimaker

sendgcode G28.

But if I login as root, and go to the /usr/share/griffin/command_util.py. Then all commands except "help" don't work and it returns error as the following pictures. How to fix this problem? Or is there any way to downgrade the firmware version to 4.3.2?

Any help would be appreciated!
