Attempting to extrude with no tool selected - During Print
-
With PanelDue firmware 1.23 I started to get some checksum errors as well. I had previously noticed some screen flicker. So I decided to replace the cable with a new recrimped one and now everything is fine again. No screen flicker, no checksum errors. My frame is grounded as well as the DC- of the PSU.
Perhaps some of the newer features in 1.23 are exacerbating existing poor cabling.

I have grounded my printer frame with the ground of 220V power outlet. Should I disconnect this grounding and instead connect the frame to the negative of the power supply output? Or must this connection persist and additionally the negative output connect to the frame? -

But if/when you use the USB connection, see https://duet3d.dozuki.com/Wiki/USB_ground_loops.

@scachi I finally got around to checking the stepper motor cables. I recrimped my second z motor and bam no more check sum errors. Thank you!
