UM 2+ Octoprint problems

Hi Guys,

I have only had the UM 2+ for 24 hours and have never touched a 3D printer before so please excuse my lack of knowledge on the subject. I have installed octoprint on a raspberry pi with the camera module and it appears to be working, however I am unable to print anything, I have no control over the printer. I have connected to the printer and can upload jobs but I cannot get any prints to work. I have read pages of information and changed the settings in Cura to Marlin/Sprinter as someone else recommended but I a getting nowhere fast.

Any Ideas or pointers please?

    Yes reprap/marlin/sprinter is correct.

    We need more details. Have you gotten the printer to work through the SD card?

    What doesn't work through octoprint exactly. Is octoprint able to read back the settings of the printer such as temperature? Does the printer start moving when you tell it to print but no plastic comes out? More details please.

    Thank you for the quick reply.

    Ok here goes, I can print fine using an SD card in the UM2+, When I try to use octoprint I do see a red and blue line on the temperature graph so I assume it is getting a temperature reading. I can upload a file the press the print button button and looking in the logs the status changes to "printing" the printer does not start moving and no plastic is released from the nozzle. Eventualy I get a timeout error in the logs.

    This might be an OctoPrint issue. Take a look at the OctoPrint system logs on your device (Raspberry Pi I guess). Should be in the home dir where you put OctoPrint.

    I will try and check the logs this morning to see if I am missing something.

    @vince805 yes the baud rate is set to 250000 and I am using gcode files created with Cura

    I have attached a settings screenshot.5a331a6e7c9c2_octoprintsettings.thumb.JPG.4c458e12a9c3c2d33c0a893d01b9890f.JPG

    I have checked the logs and dont see anything obvious, I am getting the following output in terminal:

    Well that portion of the log file looks okay I guess. For example it sent an M105 and got back that the temperature of the nozzle was 23.4C.

    Maybe you should look further down in the log file. marlin gcodes can be found here:

      • S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
        (Sorry, was out of office when this released)

        This update is for...
        All UltiMaker S series  
        New features
         
        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.
