Cura 3.3 - Bug in Pause at Height Plugin

If using the Pause at Height Plugin with layer-numbers instead of height there is an unexpected move to x 0 y 0 before resuming the print.

gcode with pause at height:

gcode with pause at layer:

    Sorry if these are dumb questions:

    1. If i used the extension in that way, how would the bug manifest itself?  I tried this over the weekend (and should have done so with a test print), but I ran it on a piece I was hoping to be a success and, when I resumed, the bed continued back upwards right into the nozzle, creating a burn hole in the print before I had to manually stop it.  It also caused the filament in both spools to retract way back into the PTFE tube, causing me to essentially remove all of the filament and refeed it to start over.  I did the pause at layer and not at height.
       
    2. This is my first time using (or even finding these extensions).  How likely/quickly will an issue like this be resolved?  Does your discovery have a fix we have to wait for or something we can/should do ourselves?

    Thanks!

     

    UPDATE:  I think the Z in the bottom code is also a bug. That might explain why my print crashed into the head on resume.

     

    Either way...Good catch!!!

    Here is my examples of height vs layer:

    I can confirm what is stated above. I'm on Cura 3.3.1 and have had the head crash into the piece when using pause at layer. Hopefully this gets fixed. I know it can be edited in the GCODE manually, but the reason for using a plugin is so that you don't have to edit the code by hand.

     

    Thanks for looking into this.

    @chuckmacgee:

    You're right. In my test-case I didn't realize that the Z1 is a problem, because on 0.2 layer height pause at layer 5 = Z1 ?

      • 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.

      • Ultimaker Cura 5.6 stable released
        Cura now supports Method series printers!
         
        A year after the merger of Ultimaker and MakerBotQQ, we have unlocked the ability for users of our Method series printers to slice files using UltiMaker Cura. As of this release, users can find profiles for our Method and Method XL printers, as well as material profiles for ABS-R, ABS-CF, and RapidRinse. Meaning it’s now possible to use either Cura or the existing cloud-slicing software CloudPrint when printing with these printers or materials
