Checksum errors

aidar

Hi

https://duet3d.dozuki.com/Wiki/Gcode#Section_M575_Set_serial_comms_parameters , check S parameter of M575 command.

3dware

M575 P1
Channel 1: baud rate 57600, requires checksum

aidar

Turn checksum requierment off and try then.

3dware

M575 P1
Channel 1: baud rate 57600, does not require checksum

now the error still comes

3dware

I have the problem only with the paneldue 1.23.2

I do not have that with the old 1.22

3dware

I have now switched to a duet ethernet and still have the same errors.

I had similar issues. For me the fix was using a shielded cable for the paneldue connection and having the shield connected to the - panel due pin on the duetwifi board. The correct solution for my case should be grounding the whole printer correctly.

Do you get the checksum errors when the printer is idle, or only when it is printing?

3dware

Only when the job run

3dware

And the print job is just finished in the middle of the program. Then the printer can no longer operate and only after a network reset it is reflected

dc42

Please post a new M122 report when a job has been running and checksum errors have been reported. I am particularly interested in the Hiccup Count. Note, every time you run M122 this value is reset to zero and starts counting again. So start a print, run a job until several checksum errors have been reported, then run M122 and post the results of that command.

Also, please post your config.g file.

I am having similar issues with prints just randomly stopping and the printer not functioning till its reset. I am also seeing the same checksum errors.. Has there been any resolution found yet?

@NAK_3D It looks like the OP never responded to @dc42 request, so we haven't been able to track down the bug. Could you?

Was that M122 run during or immediately after running a print during which checksum errors were displayed?

NAK_3D

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

dc42

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.

NAK_3D

@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.
