calling CuraEngine from the terminal (possible bug... although probably I'm doing something wrong)

Posted · calling CuraEngine from the terminal (possible bug... although probably I'm doing something wrong)

Hi good day.

 

I have a rather strange situation (don't know if someone else has crossed with it) . 

 

I'm running Cura Engine from a ubuntu 20.04 terminal which (at first) it seems like it is delivering a proper gcode. However when I check the file in Ultimaker Cura I discover that actually the height of the objects is smaller. For instance if the piece is 24 mm tall, with a 0.1 layer height, it should deliver 240 layers, however it is delivering 199.

 

What I do is this:

in the terminal (to set CURA_ENGINE_SEARCH_PATH as stated in https://github.com/Ultimaker/CuraEngine)

 

export CURA_ENGINE_SEARCH_PATH=/snap/cura-slicer/51/usr/share/cura/resources/definitions:/snap/cura-slicer/51/usr/share/cura/resources/extruders

 

then I call CuraEngine like this

 


 

/snap/cura-slicer/51/usr/bin/CuraEngine  slice -v -p -j /snap/cura-slicer/51/usr/share/cura/resources/definitions/creality_ender3.def.json  -o output.gcode   -l my_stl_file.stl

 

 

 

The output is this

I believe that maybe the problem is with the setting of the CURA_ENGINE_SEARCH_PATH variable. The truth is I'm still more of a mechanical engineer than a programmer, so most of the time I'm not entirely sure what I'm doing. 

 

I have also tried with different settings in the command line but the result always missed some layers. Here are are the settings I've tried with:

 

/snap/cura-slicer/51/usr/bin/CuraEngine  slice -v -p -j /snap/cura-slicer/51/usr/share/cura/resources/definitions/creality_ender3.def.json  -o output.gcode  -s speed_print_layer_0=5 -s layer_height=0.2 -s speed_print=50 -s speed_travel=150 -s speed_infill=50 -s wall_thickness=0.8 -s speed_topbottom=25 -s speed_wall=25 -s speed_wall_0=25 -s speed_wall_x=25 -s skirt_brim_speed=5 -s acceleration_print=500 -s acceleration_enabled="true" -s acceleration_infill=500 -s  acceleration_wall_0=500 -s acceleration_wall_x=500 -s acceleration_topbottom=500 -s acceleration_travel=500 -s acceleration_travel_layer_0=500 -s acceleration_print_layer_0=500 -s retraction_speed=45 -s retraction_prime_speed=45 -s retraction_retract_speed=45 -s adhesion_type="skirt" -s skirt_line_count=3 -s skirt_gap=10 -s line_width=0.4 -l my_piece.stl

 

 

If anyone could provide me with some light about this issue.

 

By the way I know that there are a lot of posts related the same topics but to be honest the information wasn't straightforward enough for a mechanical engineer trying to deal with programs... xD.

 

So if anyone has a more detailed tutorial to work with the CuraEngine CLI it would be greatly appreciatted.

 

 

Thanks in advance.

    Posted · calling CuraEngine from the terminal (possible bug... although probably I'm doing something wrong)

    What happens if you try it with fdmprinter.def.json as the base?
