Start G-code

[seb_odin 0]

Bonjour a tous,

J'ai une petite question concernant les start Gcode, J'ai une partie qui est modifiable facilement dans les parametres, mais j'ai une partie qui est rajoutée automatiquement lors du slicing:

(en gras la partie modifiable dans Cura)

Le problème c'est que j'ai des rétractations également (partie soulignée) dont je voudrais me debarasser, mais je n'ai pas trouvé comment. Car lorsque l'impression commence, rien ne s'imprime forcement....

 

Merci pour votre aide 😄

There are a couple of errors in there.

This Keyword is invalid: {retraction_hop_height_after_extruder_switch}

It should be:  {retraction_hop_after_extruder_switch_height}

And the speed should be F1200 rather than F12000.

 

Next is G1 E{purge_distance} F100;defaultpurge

There is no keyword "purge_distance" so that line is invalid as well.

Between the two of them they are causing Cura to not replace the Keywords with the numeric values.

 

The line you have underlined looks like the normal "Nozzle Switch Retraction Distance" default of 16mm that you will find in the Dual Extruder settings.

 

That StartUp gcode is not from any Sovol printer definition that I have.  Have you customized it or do you have any post-processors running or Sovol specific Plugins installed?

There was no alpha release of 5.4.  There was a beta release.

All the Sovol SV04 definitions use the same StartUp Gcode.  It is the bold text in your post + the next two lines "G92 E0" and "G91".

The lines below are being inserted in different way.  It looks like you may have a post processor or a plugin installed.

Cura would not insert this by itself.

G1 Z{retraction_hop_height_after_extruder_switch} F12000
G90
G92 E-16
G1 E0 F1000 ;Restore E position
G1 E{purge_distance} F100;defaultpurge
G92 E0
G4 S3
G1 E-16 F1000

 

A post-processor that is loaded is indicated by a red rectangle next to the slice button.  It will have a number in it which tells how many post processors are installed.

A plugin is generally loaded from the MarketPlace.
