@dc42 The problems seems to have gone away with the new RC3. Thank you for whatever was fixed

Everything is working now. Thank you so much for the quick help

Thank you so much for the link. Kicad source is awesome. It goes through a 10k to the MCU. Its showing a much lower static resistance on one direction. I think that usually means a bad internal diode in the package. Oh well. I'll likely just live with it on this board.

After the mishap I added a Schottky diode and its working on the Z stop. Thanks again.

@dc42 Testing new version now. Sorry for not doing this sooner, I had too much going on.

ESD doesn't make much sense to me since it only happened on RC3+. I'll check the ground anyway. Grounds can cause so many flakey issues, right? :). Thank you for all you do.

@droftarts I will after this 1-2 hour print finishes. I flashed it twice and both times it restarted within 30 minutes (I was out of the room so it might have restarted multiple times. Just to be clear, I'm not asking for troubleshooting help as I am fine with downgrading to RC2, I just want DC to be aware of the problem. I'll follow up shortly with M122 logs again. It reboots while doing nothing, just sitting there idle. I only noticed because the fan turn on like they do at power up

@droftarts Hi!

With rc3+ I had reboots. Is there more than one rc3+?

@gloomyandy anything more you want me to provide? I need to flash it back in a bit for a couple of prints, but I can collect whatever info you need.

To be clear, RC3 printed fine, but it only loaded the css file once in maybe 100 tries. RC3+ reboots while idle. I know at least once in 30 minutes, probably more since I wasn't in the room.

Hi! I had issues with 3.5.0-RC3 where the css was consistently not served on My Duet 2 Ethernet. I found the updated RC3 on the forum that fixed the issue. This version restarted twice while idle. I went back to RC2 and that seems to have fixed the issues.

I just wanted to raise this incase it's an issue that needs to be addressed before release. I didn't copy the entire M122 (I should have) but this was from after the restart. If there is anything I can do to help, just let me know. I do not need help fixing it, since I am fine on RC2.

Thank you both! It turned out to be the change in the M593, input shaping. The discord helped me figure that one out. I didn't realize the old algorithm was not in the new firmware. I have an accelerometer coming so I can really tune it now. thank you both for the great hardware/software.

Hi all. Is there an archive of release candidates anywhere? It looks like they have been removed from GitHub. I am specifically looking for 3.2-RC2. That seems to be the last version of the firmware that worked for me without layer shifting. I am trying to load that firmware again to compare to 3.2 and newer to see if the shifting goes away. I have two boards and both have this issue. Before I updated the second one from 3.2-RC2 to the latest, it worked perfectly. Thanks all! Hopefully I can figure out what I am doing wrong and get this fixed.
