What is the problem?
The print does not start:
For some days now I keep on getting these messages in Terminal:
Send: N12 G0 F3600 X80.178 Y106.471 Z0.3*28
Recv: Serial Error: Line Number is not Last Line Number+1, Last Line:9
I already did some restarts, for Octoprint, for the machine, made new files, etc.
In between nothing changed, or it must be an upgrade to Octoprint 1.3.8.
I don't have info about my firmware; I have a Profi3DMaker, which did not have upgrades since we bought it (4 years ago). Until now, it ran fine!
What did you already try to solve it?
Rebooting, shut off and on again (both the Pi and the printer)
Additional information about your setup (OctoPrint version, OctoPi version, printer, firmware,
serial.log or output on terminal tab, ...)
Many thanks for help, since printing now is impossible.
