Dual Head - Trouble

Post by Dominic » Mon Feb 22, 2016 4:14 pm

Hi there,
i have a felix 3.0 single head updated to felix 3.1 dual head. Today i got the update from repetier host to v1.6.1

Which Extruder do repetier Host prefer? Do the software print with extruder 1 primarily and use extruder 2 for support only?

for nomenclature (start situation):
extruder 1 - filament 1
extruder 2 - filament 2

Because i can not start printing with extruder 2 instead of 1. That means i have to change the filmant if i want to print with filament 2 (filament 2 to extruder 1 and filament 1 to extruder 2)

Note that it also depends on the slicer and whether the slicer is set up for handling extruder selection. Other than that, in the Manual Control tab in Repetier Host, there is a drop-down menu right beside the current X Y Z coordinate readings.

sorry for the late reply.

i found my problem last week. the g-code was for single Extruder... :roll:

it works for now. but i have to calibrate the printer for good looking results.

if u choose extr. 2 in the ObjectView it doesn´t effect CuraEngine. So i did some changes in the g-code:
