    XYZ Stops and extruder retracts suddenly

    in Improve your 3D prints

    Posted

    Nope, it's all standard. What I've just done, was do a clean install of Cura 4.

    Now I can see the G92 codes that are needed, are indeed there.

     

    I also noticed that saving a file after slicing is done in seconds, where before it was minutes.

    So I guess that somewhere in the upgrade from 3.6.0 to 4.0.0, something went wrong.

    And despite having this in my start G-code: 

    G1 Z15.0 F{travel_speed} ;move the platform down 15mm
G92 E0                  ;zero the extruded length
G1 F200 E3            ;extrude 3mm of feed stock
G92 E0                  ;zero the extruded length again
G1 F{travel_speed}
M117 Printing...

    The generated code was this: 

    G1 X0 Y0 Z15
;zero the extruded length
G1 F200 E3
;zero the extruded length again
G1 E0
M117 Printing...

    And I didn't notice that G92 was missing.

    I would say your answer pointed right to the problem, and re-installing solved it.

    Thanks a lot!

    I found out another thing, when I examined the gcode again. 

    I know for that the last time the extruder reversed, the Z position was at 28. At that height, I saw that I have a blank line in my code, and nowhere else (except for the header).

    In the same block, the extruder value drops from 4158 to 0.04. Is this an error, or not?

    Here is the piece of code:

    XYZ Stops and extruder retracts suddenly

    Hi all,

     

    I’ve got a Anet A6 running the latest Marlin firmware, and I am using Cura 4.0.0.  The last print jobs I had, after being at 80% or so from the print job, all the axes stop moving. The extruder is then retracting the filament for minutes. Then suddenly, the printing resumes. Which of course is not working, since the filament is out of the (bowden) extruder.

    I have taken a look at the G-code,although not too sure what I have to look for.

    Any ideas what to look for in the code? Or other ideas for solving this?

     

    Regards, Dick
