Given all the troubleshooting you have done, let me ask a potentially stupid question:
How old is the nozzle?
A worn out nozzle can result in all kinds of odd printing behavior, especially around inconsistent extrusion. I chased my arse for way too many hours on my previous printer, on;y to have a nozzle change resolve nearly everything.
Along with that, have you taken a good look at your extruder? A worn/broken gear can cause all kinds of headaches.
I’m not familiar with the Snapmaker U1, what I am finding is that it’s a tool changing machine. So, does the problem persist across multiple tool-heads, or is limited to a single tool-head?








I’ve dealt with slow RDP sessions while fixing servers in the past, but the lag on this connection must really suck.
