So I created a custom filamment. I have been using it for weeks on multiple projects. As of today I have it in my filament drop down in a project. It was set up as global and used in multiple projects. Today I try to print a project that I’ve already printed and I get the (!) for filament when I try to send the job. BS wants me to set the filament. I go to Device panel and I’ve got “?” for filament. I select the filament button and get the filament wizard but my filament is not in the dropdown anymore. If I go back to “Custom Filaments” I see my custom filament in the list. If I hit edit I get the a window that has empty “Basic Information” and “Filament presets under this filament” is empty. There is no filament setting listed (which is the problem) but I hit the “Add Preset” button nothing happens. The errant filament won’t delete either. I had another custom filament so I change to that and that seems fine, so it’s just the one custom filament of two that has for what ever reason broken.
