Prolème GCode

[Zebulon17 0]

Bonjour tout le monde,

Je ne comprend pas pourquoi lorsque je lance une impression l'extrudeur se vide complétement, ce qui fait que le temps que le filament (PLA) arrive à la buse l'impression à commencer...

Je ne sais pas si sa viens du G-code ou du firmware de l'imprimante???

 

Mon imprimante est une WANHAO Duplicator 12 / 230 M2 PRO avec  le 3D TOUCH D12.

Printer: D12/230 5TMC BL
Firmware: Marlin 2.1.2.1. HS V0.51BETA
KILPPER Firmware: MKS3.2.BIN

 

Je vous joint un extrait  du code pour vous faire une idée de mon problème et surtout où sa bug, vous pouvez télécharger en pièce jointe le code complet  plus le ".STL" qui à servi à générer le G code ...

Merci à vous pour votre aide.

Cordialement

OK, back to business.  There are serious problems in that StartUp Gcode.  The G92 E0 line that is commented out is part of the problem.  Without it, the printer isn't synced to the E numbers in the gcode and definitely doesn't know where the end of the filament is.  It makes for a huge retraction when the StartUp Gcode ends with the E at around 150 (maybe).  Then after the layer start the G1 F4200 E0 is telling the printer to move to 0 which from 150 makes for a large retraction.  It isn't the only problem.

I would make the startup something like I've scribbled below.  It should work provided the extruders don't have their own StartUp Gcode.  If they do then they might cause problems with this code.

 

Start by making a project file ("File | Save Project") and post it here.  It will also be your backup if the code below doesn't help.

After making the project file, in Cura go to "Settings / Printer / Manage Printers" and then "Machine Settings" and clear the StartUp G-Code box.  Then copy the code below and paste it into the StartUp G-Code box.

 

;-----StartUp G-Code
M140 S{material_bed_temperature_layer_0}      ; Start to heat the bed
M109 S175      ; Warm up the hot end a bit and wait for it
M190 S{material_bed_temperature_layer_0}      ; Heat the bed all the way and wait for it

G28      ;Auto-Home

G29      ; Auto Level
G0 F1200 Z7      ; Move up
G0 X0 Y0      ; Ensure nozzle is at the origin to ooze there
M109 S{material_print_temperature_layer_0, initial_extruder_nr}       ; Heat the hot end to Initial Layer Print Temp

G92 E0       ;Reset active extruder

G0 F5000 X1 Y20 Z0.3       ;move to purge start

G1 F1500 X1 Y200.0 F1500.0 E15       ;draw 1st line

G0 F5000 X4 Y200.0       ;move over 3mm

G1 F1500 X4 Y20 E30       ;draw 2nd line

G1 F1200 Z1.0       ;move z up
;-----End of StartUp

 

You only need to print the first layer of a file to see if the above will work.  Post the project file first though.  There can be an interference if any Extruder StartUp Gcode isn't taken into account.

Dans le forum "lesimprimantes3d.fr", un certain Maverick17 a posé exactement la même question... 😄
