unknown commands

Hi,

I have been playing around with firm and hardware recently so who knows what could have happen but I have been spotting these broken Gcodes in the console during printing:

Unknown command: "9367"
Unknown command: "ok"
Unknown command: "0 F1002"
Unknown command: "ok"
Unknown command: "00 F1002"
Unknown command: "3738"
Unknown command: "ok"
Unknown command: "ut82 Y29.092 E0.0283"
Unknown command: "255823.555 Y-4.558 E0.0418"
Unknown command: "ok11 Y-13.893 E0.0622"

They look like broken commands or somehow got messed up. Im printing with Mairln RC7/Bugfix and tethered, but this is the first time that I see something like it.

I have been having a very similar occurrence. It happens right after homing my printer. Here is a sample of the error output. It does not stop.

those are very consistent at least^^

If you're printing over usb, lower the bits per second speed you're connected at.

yes i am and i almost suspected something to do with the connection. Whats the reasoning behind lowering it, wouldnt that mean less speed and more errors?

No, not everything can communication at 250000 bps without errors, but using a lower speed can fix it.
