PanelDue warnings and errors after homing

Are you not seeing the same errors in DuetWebControl?

Inno 3D

@droftarts I've checked the wiring and it seems that there is everything ok.

No I don't using the SD card slot on the PanelDue.

@bearer no in the DuetWebControl there isn't any error or warning

Many Thanks

Are you using the 4-wire cable or ribbon cable? How long is it? Is it running next to other wires?

This is certainly a comms issue of some sort. The paneldue is normally send M408 commands regularly and reads back the status. Because you are constantly getting M508, M4080, etc it's probably the serial signal that's getting messed up.

The stepper motors are enabled when you command motion for homing, and these tend to be electrically noisy. You can check to see if any motor cables run near the paneldue cables, this could cause interference. You should also check the paneldue cables to make sure all the crimps are making good contact, there is no damage, it's plugged in securely etc. Also make sure the cable is not too long. My money points towards being related to the motor cabling as you say there isn't any issue until you move the system, and generally the motors will not be enabled on startup until you command a move.

You might also be able to reduce the baud rate of the paneldue and the duet, slower baud rates might reduce the bit errors. You can reduce the baud rate by using the M575 P1 command in your config.g, and selecting the same baud rate on the paneldue setup menu. This would be a workaround rather than a fix though.

@Phaedrux I'm using the 4-wire cable. I think it's 2.5 m long. Yes it's running next to other cables.

I think, I will test it whitout any cables next to the PanelDue Cable.

@nhof no there isn't any motor cable which is near the PanelDue cable. I will check the cable and give fedback.

How I said, the cable is 2.5m long. Is it too long?

Ok I will check the cable and give feedback.

Many thanks for help!!

@Inno-3D said in PanelDue warnings and errors after homing:

That depends on how thick the wires are. The resistance per conductor should not exceed 0.1 ohms over that 2.5m length.

I had two other wires next to te PanelDue wire.

I've removed the wire and now It's working perfectly!

Many thanks for your help!!

Were they stepper motor wires? Those are the worst for creating interference in adjacent wiring.

I am getting strange errors on the PanelDue as well. It started after my upgrade to 3.1.1. I just found this post and I am curious if it is now just corruption going to the PanelDue. Can that corruption between the paneldue potentially cause strange print behavior as well?

After the upgrade to the latest FW I had to set the panel baud in config.g
M575 P1 S1 B57600

Panel seems to work fine other than these random messages while printing.
