Checksum errors
-
@dc42 the M122 was run during a print after several errors had occurred.

The hiccup count is zero, so it's not likely to be caused by the processor being unable to service the interrupt. My best guesses are that the PanelDue cable is running close to a source of noise, such as a stepper motor cable, or that the cable it too long or too thin to pass the data without risk of corruption (resistance per conductor must be 0.1 ohm or less), or a bad crimp connection.

@dc42 That's unfortunate... This means there is still an unknown issue causing the duet to randomly reset..

The M122 report you posted earlier shows that the last reset before you ran that was caused by power up. If that was one of the "random resets" you talk about, then you have a power issue.

@dc42 @NAK_3D this morning i started a 15hr print and it stopped in the afternoon. When i checked the M122 (see below) it did a reset and cause: power up. Also i had the checksum error (see picture below) on the screen.
It looks like i have the same issue as @NAK_3D?
@dc42 in regards of the power up cause -> is this an issue of not enough power, powerloss? shortage?

not sure if related i just did a test print and got following error
Error: G10: Attempt to set/report offsets and temperatures for non-existent tool: 1
Error: G10: Attempt to set/report offsets and temperatures for non-existent tool: 2 -
@calibanorg That sounds more like SD card corruption, which may cause the checksum errors and random power cycles. Have you tried a new card? Are you using the SD card socket on the Duet or the PanelDue?

That was just an example of the checksum error.. that log was not from a reset condition.

I'm printing off of the original SD card provided in the Duet (not from Panel Due) and I've only loaded approx 6 files to it. If its a corrupted SD I'd say it must be defective as its barely used..

My reply about SD card corruption was in answer to @calibanorg, not you. I've edited my post to make that clear. Ideally people should start a new thread for their problem to avoid confusion, but it did sound similar. But then you weren't the OP, either.

@NAK_3D We really need to see an M122 after a reset event.
A couple of other things that are worth trying to isolate this:
Are you uploading gcode files to the Duet while printing? This can cause corruption.
Have you tried removing the SD card from the printer, put it in your PC, and copying a gcode file onto it directly? Does that create checksum errors?
Have you tried running gcode files in simulation mode, and see if they produce checksum errors?
Have you checked the things @dc42 suggested:My best guesses are that the PanelDue cable is running close to a source of noise, such as a stepper motor cable, or that the cable it too long or too thin to pass the data without risk of corruption (resistance per conductor must be 0.1 ohm or less), or a bad crimp connection.
Is your PanelDue connected by the ribbon cable or the 4-wire cable? As you're not using the SD card, use the 4-wire cable, it's more robust. Make sure it's routed away from potential sources of noise.
Not related to your problem, but delete or comment out the M587 line from your config.g. As it says in the gcode dictionary:
This command must not be used in the config.g file
Important! Do not use M587 within config.g. As well as being a security hazard, writing the access point parameters to WiFi chip every time you start the Duet may eventually wear out the flash memory. Also, the wifi module does not get enabled until the end of running config.g. It is better to use a macro to send M587 (source: https://forum.duet3d.com/post/42798)Ian

@droftarts i'm using the Duet SD card socket. I guess i will replace the SD card to make sure this can be ruled out. I checked yesterday the cables and rerouted them so the noise should be less. I started the same print this morning and so far it still printing since then. Another 3h 40min to go so wish me luck i don't have an issue here.

@NAK_3D my apologize that i hijacked your post
@droftarts i will open a new post next time -> Thanks for help anyway.
