Just had a power outage in the middle of my 30h print. Damn electric company decided to do some work today. Anyhow, tried to resume, and the H2D decided to drop the plates Z way down, and began resuming about 5" above where it should have. Seems to be a bug in the resume logic there.

If you are on firmware 1.01.04 read this, and make a reply on that thread, seems to be a bug in the FW , I had it too but noone else could replicate it .

I had the exact same thing happen on a 4 day print. I had 2 hours left and lost power. When it resumed it tried to home right into the part. This needs to get fixed.

I found another weird bug. I was not able to replicate it but heres what happened. Power is lost. At the moment my H2D and the P1P that is next to it was printing, and well… stopped because of power loss.
Power is Back
I click resume on H2D and im ready to take out the print from P1 as it had left just 2-3 layers that I didnt care and it was abs so it would be horrible anyway.
But the moment I clicked resume on H2D , the P1 RESTARTED its print. Im certain it happened when I resumed on h2d as at the same moment I heard the P1 go into heating mode, and 2 seconds later it was restarting the print. I was lucky to remove the print fast enough, no damage done, and I left it to see what it would do and if it just homed to “Resume” but no, it just…started printing again on its own.
This actually happened to me not long ago. I put in a ticket and gave them everything they requested. They say the R&D team has pinpointed the issue and will resolve it in the next firmware update.
This just happened to me last night while printing an airless basketball and how I got it to resume!
Not sure how long breaker had tripped, but when I flipped it back, both of my AMS 2s remained steady white on all 4 nozzles and aren’t detected by the H2D (just shows 1 ext reel for both sides with a ? Over it)
I was using the TPU 95A port to feed the right nozzle (bypass the buffer) with PLA-HR.
I also have a firmware update that popped up mid print.
When I hit resume print, the nozzle moved a little like it was homing and then just stopped in the same(ish) location it got stuck at during the outage. Heatbed and nozzle didn’t indicate they were heating up. I waited 5-10 mins or so and still nothing.
I flipped it off/on with various combinations of removing ams, restarting print from different screens, etc, nothing worked.
Then I tried plugging everything back in and gave it another reboot via switch in the back and just let it sit for about an hour. Progress light states flashing red.
Then when I hit resume it started heating up and homing properly and got back to work! Ams are still in an error and showing a message to reconnect. Both nozzles are showing the last external filament I had loaded on them. (HIPS on left, TPU on right).
My guess is that since the print file is huge it took the printer a bit to settle where it was at before it could resume. Not sure what’s happening with the AMS units, but I’ll figure that out after and do the firmware updates.
Currently, I’m on 01.01.04 on the H2D and 02.04.19.87 on the AMS.
I exported logs after some of the troubleshooting if it can help, but not sure it’ll matter after updates.
