Wondering if there is documentation I am not finding on idexx machines. I have my dual gantry dual head corexy printing and was wanting to start a dual head print in ditto mode. But I'm not finding the documentation on it.

@dc42 Has this changed at all? It would be nice to have it pause and only stop heating the heater that faulted not the bed. Can this be changed somehow? Also if it was a true pause instead of timing out and going away after so long would be awesome as well. Most of the time the print stops in the middle of the night and I don't wake up early enough to get to it. I don't see any reason for making it time out or having the other heater stop.

@Veti you are right sorry I pulled from my 2.05 version. and 3.1 I only have working on duet 3 so far.

@alex-cr ok so if I heat my tool they both light but fail because of how slow. PID tune will only heat one at a time. @dc42 is there a way to pid tune both at the same time?

@alex-cr this is what my config looks like now.

@alex-cr that's how I have em and the e1 won't light and heat. Maybe @dc42 could chime in?

@alex-cr ok how about a dual heater cartridge to even the heating on the block?

I have installed a new hotend that uses dual thermistors. I'm hoping to set this up to where one is a redundant backup. Is this possible? If so how do we do it? Also is there a way to set it up to take an average if the backup is not possible? I also need to figure out how to wire two heater cartridges and use separate heaters. I think I have it right but duet doesn't seem to send power to the second.

I am seeing this same issue on one of my 3 duet 3 setups. All the wiring is correct, and configs are the same on all three. Two of the machines work no problem this one just quit out of no where.

@Phaedrux as well as the duex 5?

@Phaedrux they stopped working within an hour of being configured. I don't think the duex 5 ever worked.

@droftarts all of the fuses are fine unfortunately.
