Bonjour bill un autre petit souci j ai mesuré la longueur de mon tube ptfe entre l extrudeuse et la buse se qui correspond à 375mm que j' ai rentré dans le gcode le souci ces que l'extrudeuse quand elle charge le filament elle ajoute presque 120 mm de plus je voudrais savoir où modifier le gcode pour réduire la distance en fessant des testes car au départ je me retrouve avec un gros paté sous la buse

In the end of the Tool Change GCode, there is a block that loads the filament. You can adjust it by reducing the last two G1 commands. Look at the bottom of the gcode for this section: G92 E0
G0 E100 F2000
G92 E0
G0 E100 F2000
G92 E0
G0 E100 F2000
G92 E0
G0 E100 F2000
G92 E0
G0 E50 F2000 ; <<<<<----------- EDIT THIS DISTANCE TO FINE TUNE THE FILAMENT LOADING TO STOP BLOBBING OR UNDEREXTRUSION You can remove one of the G0 E100 lines to reduce it's loading by 100mm... and then you can reduce the G0 E50, to G0 E30 to reduce it an additional 20mm. Also, the blobbing is because it is still pushing the filament to the tip... you can reduce that loading block even further if needed. The ideal position to load the filament is just a few millimeters before it reaches the tip... so it can't extruder before you want it to... then when it is purging into the purge block, the filament will start to extrude. That way, there is never a blob created... and the transitions are always hidden in the purge block.
