Just had a quick look at section 3 of the guide (setting up Cura). towards the end, it says:
"Ensure Support is off and Build Plate Adhesion is set to None"
And shows picture of unchecked Generate Support. But this setting isnt visible (lots of other support settings are). I clicked the cog button next to Support, to bring up visibility settings, and Generate Support is checked (as I checked them all at earlier step as it said to), but the "i" information icon to left of it says "this setting has been hidden by the active machine and will not be visible". It's not clear if its hidden AND support is disabled, or if its hidden but support is still enabled?
Rest of parts 3 looks good.
Cheers,
Peter
