Has anyone had the following problem and been able to work out what is causing it.? My AMS unit operates perfectly for maybe a couple of days and then all the four lights on the unit gently start to flicker. Generally speaking the spools still read for awhile and feed through to the printer ok however on one occasion the unit failed and would not read the filaments and would not feed them through to the printer. I changed the cables. I’ve cleaned everything but have not replaced any electronics or filament tubes in the AMS. I just replaced the connecting cable which by the way is connected to an AMS two which is then connected to the bamboo labs. H2S. Can’t seem to work out what would be causing it to work perfectly for awhile and then suddenly start to flicker and then as I say on one occasion stop working altogether. Turning the units off and turning them back on fixes the problem for awhile. Interested if anyone else has had this issue and been able to sort it out. Maybe I should daisychain the AMS units with the AMS 1/ first plugged into the AMS2. That will be my next thing to try.
