Recently replaced motherboard on Mini1 due to USB becoming detached. I am using the latest software (Windows Stable) and newest firmware. I also printed that part to stop the detachment again.
Printing objects about 6mm in height and 65mm x 65mm. Putting four on a bed. The first part of the print works beautifully. Filament gets laid down nicely. The estimated time to print seems reasonable. When I get to just over 60% the printer slows down considerably. My the time the print finishes it is over double the estimate. The tops of the prints are very rough and the head is moving very slowly.
I did not do anything with E stops when I replaced the motherboard. I do notice that the head seems very close to the print and scrapes the plate slightly when starting (really just displaces the glue) but eventually filament comes out so though all was fine.
Any help would be greatly appreciated. My USB cord is not very long. Using NGEN filament at the default presets.
