I just bought a height extension for my Ender 3 Pro, and I figured out how to change the z-axis height in the device tab, but I wanted to know how you change the profile the slicer is using, as it does not change when I select a new device. Once I find out how to get the profile to change, is there a way to get the z-axis to change on the profile?
With the device selected, click the
customize button at the bottom of the dialog. That will clone it. Then you can just exit the Z height for your custom device.
