Hello DMKprints
1, you may not use the cura slicing software, it is recommended to refer to the picture to modify the extruder’s start and end G code. (Left and right extruders are the same code)
Start code
G92 E0
G1 Z{retraction_hop_height_after_extruder_switch} F12000
G1 E-{switch_extruder_retraction_amount}
G92 E0
End code
G92 E0
G1 Z{retraction_hop_height_after_extruder_switch} F12000
G1 E-{switch_extruder_retraction_amount}
G92 E0
Thank you
Best regards
