The new PID TUNING function work sooo much better !!!! can't believe it !

Thank you guy soo much

I just did that swap, from a replicator 2 to duet 3. check your chat Ill help you set it up

@fcwilt they are running independent, one feeding the main 6hc and the second feeding both 3hc's (each power supply have 3 output)

It did work, and the m112 / m999 does work on all ext now. no more stepper motors flying anymore XD

@Phaedrux
I did but they didn't gave me any info, so I did it again and recorded the whole thing.
video here (1.30 min)
the video is not publish publicly, you can only see it from the link. I didn't want people to have the wrong idea.

you can see at 1:20 everything just *freeze as the whole system just quit.
when I reboot I have no error message or anything, it just boot as usual.

@Phaedrux I realized something else: the pi actually do a reboot when the board shut down, it doesn't just loose power.

@Phaedrux
So I did flash them to the last update (they where at 2020-12-20, they are now at 2021-01-05)
and here my m122 and m122 b1/b2

@Phaedrux
m550 I have that on all my machines, never took the time to look into it..

I will launch another "test run" tomorrow then take the m122 from all the boards when it crash

@fcwilt they are running independent, one feeding the main 6hc and the second feeding both 3hc's (each power supply have 3 output)

@Phaedrux I should had started with that.. Ill upload that tomorrow morning (Canada time)

I started to push one of my machines as it was finally stable, and I am running in a probably really easy to fix issue..:

As soon as I pass the 150mm/sec printing speed, the whole system reset :
--The system:
6HC (1 extruder + 4 z motors +raspberry pi (i know i know.....) ) running on 1x 15 amp 24v power supply;
2x 3HC (1xX 1xY) as the machine is a double H-Bot (2X and 2Y).. connected on a second 15 amp 24v power supply.
all my motors are running at 1.2 amps for Z and 1.4 amps for X/Y. temp is good and they are stable for 96hrs + runs.
--Why 2 power supply : at first I tough I was running out of amps when everything was kicking together.. actually helped when I added the second one. Now my power is stable at 24.1V the whole time, and the cooling fans wont event run at full speed on the power supply.

SO I think im good with power... is it possible that I am running out of memory ?

I know that nobody in his right mind would even try to print over 120mm/s but im running a ultra light mostly carbon fiber gantry and she can move .. with the double h bot she is also perfectly stable when she do.

I know I am pushing the limit here but I want to see what your board can do XD
