Hi all

I had the problem described in the main craftbot thread with the unrecognized build plate.
So I tried to downgrade the firmware to the version before the newest.

Now I get the following error
Mainboard communication error.

And during the fw upgrade process it says
Step 8/10 Mainboard update

Mainboard error. :Operation failed

Any idea how to get back to a working system?

Thanks for helping
Oli

solved!

Removed the usb cable going into the lcd on the front side and restarted several times. Then reinstalled the usb and did the regular firmware update process. Now ok!
