What is the problem?
Getting a probing failed error and connection closed on gcode files that used to work fine. This occurred after updating firmware to my Lulzbot Mini. Looking at the terminal, there is an error around lines- "Error:Line Number is not Last Line Number+1" in all failed jobs.

What did you already try to solve it?
Flashed back the old firmware, tried multiple gcode files, tried safe mode, flipped on "always" for simulate ok for resend requests. Also contacted Lulzbot tech support and they claim this is an Octoprint issue. Gcode files will print fine via direct USB connection from my PC.

Additional information about your setup (OctoPrint version, OctoPi version, printer, firmware, browser, operating system, ...)
Running Octoprint 1.3.11, slicing with Cura lulzbot, printing with Lulzbot Mini (v1)

2

It kind of looks like your firmware got confused about a basic G0 command. Given the response, it sounds like this is a send error to the controller board.

Review the serial cable (should have internal metallic shielding or a ferrite core), it should be as short as possible and finally, verify that you're not running an undervoltage condition.

3

I swapped out the USB cable to one I know works- still getting the error. Also not an undervoltage situation. I also just re-imaged the SD card, but that didn't work. Still having that last line hiccup.

4

Trying running a gcode command in the Terminal tab and see if your firmware likes it.

G0 X Y
5

Please share a full serial.log

6

Here is a serial log from today. I also swapped out printers (we have multiple Lulzbot minis) and got the same error with the original RasPi connected to a new printer. Swapping the other way (problem printer with working RasPi) resulted in no errors, so this does seem to be tied to Octoprint on that particular RasPi.

That is an octoprint.log.

Oops- my apologies. This should be the serial log.
Mini2_10_14_19_serial.log (64.8 KB)

Tried this just now (send G0 X10 F6000 and then G0 Y10 F6000) and both worked fine. Looks like when I use the GUI controls in the Octoprint interface that it is sending a G1 command, and that the G0 command moves a lot more distance, i.e., G0 X10 travels a lot more than G1 X10.

10

Not sure if that is a typo but G0 and G1 are two different gcode commands. If you meant to suggest that G0 X10 and G0 Y10 move different amounts when seen like this:

G28 X Y   # home the X/Y motors
G0 X10    # our 1st move sideways, should be a total of 10mm travel
G0 X0     # return to the origin, should be a total of 10mm travel back
G0 Y10    # our 2nd move front/back, should be a total of 10mm travel

...then let us know.

G0 is the start-from-here sort of command and G1 is the expected move-to-here sort of command (usually associated with extruding).

11

I'm definitely limited in my knowledge of Marlin, so your differentiation of G0 and G1 explains the what I saw in the printer's behavior. I figured they were different commands but didn't understand why they would move different amounts when it looked like they have the same parameters.

Anyways, any thoughts on next steps or what's causing the error?

12

Uhm, for the record, in (mainline) Marlin G0 and G1 are exactly the same. As in, one actually just is an alias for the other.

Try disabling LayerDisplay plugin and this will go away I think.

Looks like this was a hardware issue after all. The x-axis carriage wasn't quite level, so the auto-level process would fail. Finally figured that out a couple of days ago- problem solved by hand-turning the z motors and manually leveling the x-axis. Prints fine now.
