Hi, First of all thanks for the great software. I have a 3D printer (hellobeeprusa) and I am trying to set it up as dual extrusion in Cura 2.4 beta. I've created one profile based on the ultimate_dual and changed some settings according to my printer. The issues i am facing now are two: - when i open cura the bed is not in the middle of the STL picture that i am using of the beeprusa. but the most important: - in the log i always get the message WARNING - cura.Settings.ExtruderManager.getMachineExtruders [375]: Tried to get the extruder trains for machine Custom Beeprusa Dual Extrusion, which doesn't exist.
