.gcode generated on http://retractioncalibration.com/ doesn't print on U3

Hi guys. I was advised to use http://retractioncalibration.com/ retraction test generator to tinker with and refine my TPU printing settings on Ultimaker 3. 

I generate the .gcode with the default numbers, send it to the printer via cloud but nothing happens. When I try to print it from a USB drive for a split second the printer screen says ETA is 0 min 0 sec and then returns to the default screen.

I tried changing the X and Y dimensions from 200 each to 233 and 215 respectively (as per my U3 settings) as well as putting "T1" in the Custom gcode space. Is there anything I’m missing here? 


Tried it on both Cura 4.3 and 4.8 on Windows 10 (Gcode flavor Griffin)

    Cura gcode example.gcoderetraction calibration test.gcode

    Hi Smithy, thanks for your suggestion. Please see the gcode generated by http://retractioncalibration.com/ and the random example from Cura. They begin quite differently. Do I just copy paste the header from the Cura example gcode and change the numbers so it works with the retraction test? There's info in the header such as:


    Do I need to find all this information in the retraction gcode and translate it into the header for this to work?

    Not everything is needed, there are also some comments which are not needed. I am not an expert what is needed, so maybe someone else can give detailed advices.


    But another idea. Have you tried to load the gcode in Cura and print from there or save it again? I think Cura adds the missing and needed header lines.

      • 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
