I went through a LOOOTTTTT of headache this weekend trying to finish a multi-color model! My AMS 2 Pro went bad when printing the top (multi-color) piece of my Full Sized Gandalf's Staff. At about 60% through the print, the PLA glow started throwing errors every time it loaded and unloaded. You could say I was trying to save that print for the whole day. I would get an error, then once I got past that error, it would flash another error. After that, I might get the print running for one layer, but that only takes about 1 minute. Soo I got hardly any time to do anything while that was happening, and it was happening for 7+ hours. So after doing that for hours, naturally, I stopped the print. But I did make a repair print thankfully. I cut the model at the height of which I stopped the print, then printed that and glued it onto the unfinished infill.

I don't know why it did this, maybe its the filament. It was PLA Glow Blue, so it was special filament. I checked the diameter of the filament, and it was the same as other filament. If you have any ideas to what caused this, comment please!

In conclusion, my AMS 2 Pro slot 1 is not reading or sensing filaments right now, even though it will pull filament into the printer for some reason. Plus, my other AMS (2 Pro) is currently clogged with a piece of broken filament (I think 😬). 

Buuut... I finished the model! It turned out great in the end, as you can see (check the link below)! But it is a little more chunky than I thought it was gonna be 😂, maybe V2?!

If you have any thoughts or questions, comment!
