Recv: k

does it just stop the transmission at the k and doesn't send anything else?

Yes exactly.
Always just end with the ”k”, could be after 1min or 5min, very randomly

I suspect it's a broken response, as it should be like the others and be a complete ok like the other lines.

Which firmware are you using?

I suspect GRBL.

Yeah but maybe a fork for sandtables with bugs in it :person_shrugging:

Octoprint: Version 1.8.7
Better Grbl Support (2.3.1rc2)

I guess Better grbl support is just to remove the hello command....

2pcs Separate power supply 5V 2.5A to both Raspberry and CNC Shield.
USB cable is the one I got with CNC, quite big and fat.
