I am running Cura Lulzbot edition 3.6.21 with a Mini. I changed the tool head to an IT-Works E3D Titan Aero to use 1.75 filament. The physical change went fine. I added the printer to Cura and changed nozzle to .4mm and filament to 1.75. Cura said I needed to update the firmware, which I did.
When trying to use Cura there was no material selections, just an empty drop box. The only profile was a standard one. No other selections available. Both filament manager and profile manager windows are empty. If I try to create a material in the material manager the program closes. I can’t do anything in the profile manager. I used the profile drop down box, again which only has the standard profile. I selected “create profile from current settings/override…” in the drop down box. It brought up the profile manager and another pop up window asking for the new profile name. I typed in the a name and it took it. Profile manager window still empty and back to drop down box has the new name.
Next I deleted Cura, cleared the cache and reinstalled. Still the same problem, can’t create profiles.
BTW, before reinstalling and after re-installing I did re-select printer to original Mini and it worked. Select back to Aero and same problem.
Also, I tweaked the standard settings so I could try a print. Couldn’t save the profile but I could print from it. Got a really good print.
Any help would be appreciated,
