So I have never seen this message for a error. I have new Kobra X and have four ACE units attach to it. been having some trouble with the fourth channel feeding error. So I went and unloaded all the ace lines and then check to me sure everything was clear with them. I then reloaded them. after doing that I got a error again from fourth Chanel but not what I have received before? this is a copy of it. "

Code:11858

Anycubic Kobra X (1 printer(s) in total)

Channel 4 filament exhausted

I did not know this could happen to a machine?
