Just got my printer up and running this week. I haven’t done any multicolor prints, but I’ve used the left nozzle all yesterday using PETG Basic (I’ve a couple of rolls left) And all printed fine. I changed to the right nozzle this morning and again fine. Ran out one roll and I put in second, zero issues. So I don’t have any answer, possibly buffer…
Does having the AMS powered by the external switching power supply, make any difference with the AMS issues of failing to load the left extruder, or the warning that the AMS has excessive resistance?
AFAIK the power supply is only for the heater, the other functions are powered by the H2D.
