Electronics board problems
Good morning everybody
I hope this helps others not get into this problem or at least not to spent to much time with troubleshooting.
Yesterday I finished the assembly of my MMU2S upgrade and run into a problem during testing.
When I tried to load filament the Selector and Idler moved several times to their endstops and after some time all LEDs (red and green) started flashing and sometimes the error message «MMU needs user attention» came up in the display.
After a few attempts I noticed that the Pulley motor was not moving at all. By hand, however, I was able to turn it around. I began to check all the cables and the connections, everything was fine. In the end, I removed and checked the electronics board. And I could find a solder bridge between two pins of the Pulley motor connector #3.
After resoldering this two points, everything works as it should.
The first two prints looks great and so far I'm happy with the upgrade.
