Error Parsing Response

taylo708

Just uploaded to 3.3 beta 1 and as this is a new setup I’m not sure if that is related to my issue or not. I am getting a parsing error during printing as shown from my picture, it is constant.

Phaedrux

If it's a new printer setup, might want to stick to the latest stable release?

https://github.com/Duet3D/RepRapFirmware/releases/download/3.2.2/Duet2and3Firmware-3.2.2.zip

If you want to stick with 3.3 beta 1, please post your config.g and the results of M122 and M98 P"config.g"

Which version of PanelDue firmware are you using?

taylo708

I am using PanelDue 3.2.9

dc42

Are you running the Duet in standalone mode, or with an attached SBC? I am fairly sure that messages doesn't come from RepRapFirmware, so I think it must come from PanelDue or from DSF.

taylo708

I am running it in stand alone mode.

@taylo708 This message generated whenever the status-updates from RRF cannot be parsed correctly. Can you confirm that this is new with RRF 3.3beta1 and you did not have this issue before?

If so, please post your config.g so I can investigate the issue.

taylo708

I was running 3.3 beta1. I also have a 3.3 beta I’m not sure if they are different or not. I went back to 3.3 beta and am still getting the same parsing error.

Is there any solution for this? We have the same problem with 3.3RC2 and 3.2.11 (PanelDue). We do multiple machines a week but this is our first machine where we get this problem.

What we tried allready:

New LCD screen
New cables between board and LCD
Firmware 3.2 to 3.3RC2
LCD Firmware 3.2.1 and 3.2.11

dc42

@dvmourik I can think of the following possible explanations:

Faulty hardware: this could be the Duet, the cable, or the PanelDue. You've replaced the cable and the PanelDue, but have you replaced the Duet?
Something different in the environment, e.g. something that is normally grounded isn't on this particular machine, and that is causing interference
An obscure firmware bug that is causing RRF to return invalid JSON because of the way the machine is configured. Is the config.g file on this machine the same as on the working machines?

Does the machine respond to commands sent from the PanelDue, e.g. the Home All button?

@dc42
I just received a brand new panel due to upgrade an old one.
The new 7i causes these errors.
The old panel with extra board that plugged into it probably is 5 years old works fine.
I'm running the latest stable release of the duet firmware and also the current latest firmware for the panel 7i.

Any idea why this is causing me grief?
Considering returning the PanelDue as I believe something is wrong with it if the old PanelDue works fine.

Anything you recommend???

dc42

@pete1961 which firmware is the older PanelDue running?

I'm going to say at present after making a shorter cable from scratch the errors have stopped.
I went from about a 24" cable down to a 10" Cable.
I will come back here if I see more errors.

Phaedrux

@pete1961 Using a braid or twist on the cable can help. so can using a higher gauge or shielding.

pete1961

Yes a better cable is in order with the 10" cable I fabricated the errors are more spurious than previously but still around.
The cabling is obviously the cause of this problem.

24" (600mm) is not too long (I have a 1.5m cable on one of my machines), however there is a limit on the resistance per conductor. See the wiki for details.
