Printer just stopped, can't find the reason

deckingman

@appjaws Hi Paul. From what I can gather, homeall.g works but other macros do not. Now homeall.g is a macro so that seems strange and would lead me to suspect something other than the board - i.e. it will run some macros but not others. The difference is that the homing macros are in the /sys folder, whereas other macros are in the /macros folder. Your initial failed print was running a gcode file that exists inside the /gcodes folder. So I'm wondering if your problems are stemming from a corrupt or failing SD card. Do you have another that you can try?

appjaws

@deckingman thanks, I thought it could have been the SD card so I opened a new 32GB card and copied all the directories and files from the original card to it.
This didn't make any difference.
I even tried to enter G1 X10 but nothing happened except the rotation circle busy sign again.

I have an awful feeling that the processor is damaged , how I don't know, unless it overheated because of the hot weather. I don't want to buy another duet2 untill I am sure that it is damaged and that the dueX5 is OK.

Are you able to safely test individual motor movement commands using G1 H2 for each axis?

At this point it would help if you gave some more information about the machine and configuration. I see you have a U and V axis, so your homing files and config.g would be helpful.

I then issued G1 X100 Y100 and pressed send button but nothing happened, the button just shows the rotating circle.

This makes me think that there is something preventing the motors from actually moving. Where are the motors physically connected? The Duet or the Duex?

deckingman

@appjaws I have the original Duet Ethernet from my machine that I could lend you. It'll cost you the postage and I'd want it back. Pm or email me if that's any use.

Edit. I also have the Duex 5 so I could lend them both

@appjaws I also have some refirb duet 2s I'll be selling if you're interested

appjaws

@deckingman Thank you so much for the offer, I am pretty convinced that it is a processor fault, so I will be buying a used Duet2. In the unlikely event that the replacement board doesn't solve the problem, I'll ask you for a loan of your dueX5 so I can confirm the state of mine.

@deckingman @Phaedrux
I don't think it is the dueX5 board because I have 3 Z motors connected and they are working as well as the XU, YV and E motors.

It's almost as if the processor is only handling the first instructions and not releasing for the next set. As an example I ran my auto start macro, the macro started and the first thing it does is the set the bed temperature to 60C, when that is reached it then sets to 65C and the nozzle to 195C. What happened is that the bed reached 60C and then nothing else... very strange. This macro is used daily and is included at the end of this entry FYI.

I have calibrated the MCU temperature and it now reads about 36 degrees

Nothing has changed in my config or macro files and bearing in mind that the machine stopped towards the end of a print and the head stayed at the last extruder position instead of moving to the park position at the end of the print, I think it must be the processor at fault.

Has there been any changes in the firmware since the beta version of 3.4.1 that would require config or macro changes?

this is the start up macro:-

Waiting for @DC42 to have a look. I haven't seen a CPU failure like this before. Usually it either works or it's dead.

@Phaedrux thanks for any help, I am at a loss.
Hope the file has been uploaded this time.
M122-output.txt

That output just shows that the last reset was a software reset commanded by you 5 min 21 seconds before you ran M122.

After the update I homed all XU, YV, Z which worked fine but the homeall button just showed a rotating circle. Eventually that stopped and the button label was correct so I tried my macro auto bed levelling, nothing happened except a rotating circle against the maco entry.

Check that your versions of RRF and DWC are in step.
One reason for the printer doing nothing and DWC showing a wait-circle which goes away after a while is that the motors were unable to move, for example because the Duet had 5V power but not VIN power. Are you using external 5V power?

appjaws

@dc42 Thank you for your interest.
RRF and DWC are in step both at v3.4.1
I am not using an external 5V system, The whole system is powered by a 24V supply
I can move each motor set XU, YV, Z individually and they move as expected.
If I home just the XU then when the moves are finished, I just get the rotating circle on the "HomeX" button and I can't do anything else.
It is the same if I Home YV or Z

very strange.

appjaws

Just disconnected the boards and have found no signs of burning on the duet or the deuX5.
So still baffled by this strange fault.

Tinchus

I was having some time ago the same exact problem. What I found finally was that for some reason, the gcode file I was uploading thorugh wifi, was being uploaded incomplete. So I started the prints and the print finished when the gcode just ended. Since the endgcode was not there, everything was on: nozzle, bed...
To check this: download the file you have on the printer and open in and check if the file is complete..
In my case the problem was caused by a bad wifi conection

appjaws

@tinchus Thank you for the info but I don't think this is my problem, I can't even get the printer setup to do a print. Hopefully another board will arrive today, which I hope will solve the problem.
