I have made all updates (Cura, Marlin, Touchscreen) uploaded earler this week and was expecting that when printing with only one hotend, the other hotend should not heat up any more. However, this still seems to be the case. Do I need to change any settings in Cura when printing with only one hotend or did something go wrong updating software/firmware?
@denishungnguyen In the top right of cura there is a drop down box that you can select Layer View from. You should then be able to highlight the parts of the model that hotend 1 and hotend 2 are printing. To prevent hotend 2 form heating you need to select extruder 2 and disable the build plate adhesion (select none form the drop down).
Which hotend were you trying to print with? Hotend 1 will automatically get used for printing brims/rafts etc. and will need to heat up.
