Describe your issue:

Hello everyone,
I’m new here and new to Klipper but have used FDM printers since 2021. I bought a new LNL3D IDEX printer and using it with a Klipper Pad. When I try to print a gcode (made with cura) that uses more then one extruder the print won’t start after everything is heating up at stable temp. When only using one extruder it works fine and the print quality is perfect. I assume its not a hardware issue because both extruder are able to move, extrude and heat up stable.
Do you guys have any idea what the issue could be?

Thank you for your help!
Regards
Till
