In my opinion, as a software engineer, the core issues with the deadlock and hang ups is likely poor quality control in the software that leads to failed prints. That's also why, as far as I can tell, its common for prints to fail at the same spot over and over. To me, that's a dead giveaway that its a software issue. There are those of us that would love to have the ability to assist in the improvement in the product if we also could gain a little more control over the device. E.g. the amount of throw away filament caused by splicing failures & bad prints is > 50% of my filament use. If filament could be spliced together by feeding filament into the splicer from both incoming and outgoing side and splice them, that would allow me to save filament that's otherwise too short. Yes, you can do this if you want to spend days of your life using the splice tuner, but seriously, cutting off short segments in order to splice it back onto another short segment is dumb. I imagine it is a very expensive engineering...
NO, the PALLETE 3 PRO is INCOMPATIBLE WITH ENDERS out of the box, SEE my POSTS, and you'll find out that it will never actually start a print, and MOSAIC appears to not offer any actual support, just passive useless questions. The bottom line from what I can tell is that you have to figure out a way to import a working printer profile into Canvas. But to be honest, I haven't had success despite countless hours of fiddling around, only to have the Pallete sit there doing absolutely nothing after loading the filament. When I hit print start, nothing happens, either it's not sending commands to the printer, or it's sending commands the printer doesn't understand. My opinion, stay away from Mosaic products. Thus far, my experience is that they aren't actually helping customers get these devices working out of the box, either because it's too complicated, they're under staffed, or don't care once they have your $$$.
After doing a factory reset, and compiling then flashing a custom marlin firmware on the SKR Mini E3v3 board, I was finally able to get the printer connected, and homed all three x,y, and z.
Is this list accurate still? My experience tells me that the P3P does not work with the ENDER 3 because prints never actually start.
