2nd hotend heats up to same temp as 1st regardless of what I enter into Cura, even if I disable it altogether. Anyone have some suggestions?

Look at your startup code.
Probably you’ve got preheat code in there for both extruders.
Yes I do by default. One for each hotend. Still new to this. Are you saying they don’t need to be in the start code? If so can you elaborate? Thank you M104 T0 S{material_print_temperature_layer_0} M104 T1 S{material_print_temperature_layer_0}
The first line will heat up the first hotend, the second line heats up the second hotend. independent of whether you’re using both or not.
what I‘ve done for now (since I usually only use 1 hotend) is to comment out the line for the extruder I don’t use.
i’ve seen that the latest versions of cura have extruded specific start and stop code, but haven’t used that yet... I need to tinker with that.
meanwhile I also found you can use the replacements with an additional parameter to indicate the extruder.

enjoy!

Thanks. That fixed the issue
