@chrishamm That was the issue, when setting the static IP for the printer, it had been set up for a different network originally, then when moved to a different network only the subnet for the static ip for the pi was updated to the 60 and not the router. THANK YOU

@gloomyandy That was it. Didn't see that stop.g now runs at the end of all prints since 3.5b1 regardless of M0 being present and stop.g was set with an M999 (I assume when it was set up on printers 2 and 3 it was thought that it was for an emergency stop situation not the end of a print). Thank you for your help!

I'm also including the printers' ending gcode for reference (I can also share configs if that might be helpful):

This would be the time at which the print finished on Printer 2:
Last software reset at 2024-08-13 20:19, reason: User, Gcodes spinning, available RAM 63316, slot 0
This was not from user interaction with the printer

I could not find any reference to this issue so I figured I would post something (sorry if this is already a known issue). So this didn't happen in 3.4.5 or before, but when a print finishes, rather than going to idle status the printer(s) reset. This is at the end of every print. It also does not occur on machines running just a MB6HC. Including M122 responses for the machines that have the issue. So across three machines:

@droftarts
Thanks for responding!
To answer your questions in order:
Was the M569.5 command generated by the Closed Loop plugin?

• Yes

Are you running in standalone or SBC mode?

• Standalone

Is the SD card good (it could be the SD card can't cope with the speed at which the data is collected and written)?

• Not entirely sure how to qualify an SD card for this? It is a 16GB SanDisk Ultra micro SD (I believe the stock card that came with the board but not 100% certain of that). It has been reformatted to eliminate the partition that the stock micro SD cards that come with the boards have.

Can you send M122 B# (where # is the CAN address of the 1HCL board) when the printer restarts, which may show the reason for the crash?
M122 Prior to reconnection

M122 After Reconnection

Hey, I'm running into an issue when trying to tune closed loop for a Cartesian/IDEX 3D printer. Currently running 3.5.2 on all boards (MB6HC (1.01a) running CAN daisy-chained to a 3HC (V1.0) to four 1HCL Boards (V1.0) (For the X, U, Y1, and Y2 motors in that order).
The boards work fine as motor drivers, and the printer is able to perform the calibration motion for the closed loop. However, when I try to tune closed loop using the Closed Loop Plug in, the boards will disconnect mid tune (and then pops up with an error saying Expansion Board xx.0 reconnected, where xx is the CAN address of the board). Further attempts to run the tune will complain that there is no encoder configured (presumably because the board disconnected and reconnected). I have run into this on the X and U boards, have not attempted yet on Y1 or Y2. Additionally, the readings I do get do not seem to be anything similar to the examples in the tuning documentation.
Any insight here would be welcome.
I have attached the config, a homing script, and photos of the error outputs from the console as well as the what the Duet managed to collect on the encoder before the board disconnected.

@chrishamm That was the issue, when setting the static IP for the printer, it had been set up for a different network originally, then when moved to a different network only the subnet for the static ip for the pi was updated to the 60 and not the router. THANK YOU

@chrishamm @Phaedrux I am unable to ping anything from the pi, and the configured date/time was incorrect (although I assume that is because it can't connect to the necessary connection to update the date/time).
