Since day 1 i have connection issues when trying to send a print to the U1 from SnOrca. Latest version everywhere.
Its often taking outrageous long on the following screen
And will end in this suddenly.
This can happen multiple times in a row and i just try again until it works.
But when it works it then works basically instantly. So everytime i see the orange button and crawling progress i already know that this will fail. Does not matter if its a 60MB Gcode or 2 MB.
In the meantime after i selected the printer in the dropdown i also get little "Timeout" notifications at the bottom while still being connected to the printer, which i know because a few seconds after that "Timeout" it finishes syncing filaments an i can proceed.
My P1S in the same wireless network standing right next to the U1 had no such issue in 2 years, regardless of the network mode.
