I just bought the new Flextruder head for my Mini. Instructions said to update to the latest version of Cura (21.03).
Did that.
Now when I load a model, instead of getting the “CONTROL” button that allows me to print, all I get is a “SAVE GCODE” button. I can’t do anything with it now.
What happened?
Using Mac OS X 10.12.2 which worked fine with the old version of Cura.
Disconnect printer. (and leave that way)
Uninstall Cura completely.
Reboot your computer.
Install new Cura
Reboot again (yeah its a pain)
Start new version of Cura.
Now turn on and connect printer.
I found the issue (via a call to Lulzbot). For others that encounter this when changing a head and or updating Cura.
Be sure you go to “Machine” --> “Install default firmware”, then restart the printer, then open Cura.
