Stepper motors ports Duex5 seem to not respond anymore

PaulineC

Hey all,

I've been using DuetWifi2 and Duex5 for months for a big 3D printer homemade, and it worked perfectly until now. For some months we changed some 3D printed parts and unplugged / plugged again some wires. Now we're back to test the movement, and the whole ports linked to the stepper motors on the Duex are not responding anymore (the motors don't move).

We tried exchanging the motors connected on the DuetWifi with the one on the Duex. The 2 motors that were working right before connected on DuetWifi don't work anymore when connected to the Duex. We also tried to move the motors from drive 7/8 to drive 5/6 (and adapting on the firmware of course), and these two don't work either.

It seems to us that the whole left part of the Duex is not working anymore, but we can't get why. We have a BLTouch connected to the Duex and it works, so it's not the Duex itself, at least not all of it. Is it possible that the whole part linked to the stepper motors is dead ? Is there any kind of security that could have been activated because one port is possibly dead?

Thank you so much for any suggestions...

Have a nice day !

did you get a error message in the console if you try to move a stepper which is connected to the duex board?
Enter M122 in the console and post the result here Please and can you post your config.g file
Vin on the duex is connected and have power?

PaulineC

No we don't have any error message, nothing. It's just that half of the motors are not moving (the ones on the Duex5 board).

The M122 command gave us this :

Thanks for you help and looking forward to your answer

SIam

the first thing is your custom settings:

Order dependence

M584 must come earlier in config.g than any M350 and M906 commands. If it creates new axes, it must also be earlier than any M92, M201, M203, M208, M350, M566, M574, M667 and M669 commands.

please solve this and test again.

PaulineC

I tried moving the two M584 commands in the begginning of the file : still same results.

SIam

you will use port 5 & 6 on your duex but the m569 p5 & p6 is missing and you write as commend that you have 4 Z motors there are only 3 configured

PaulineC

Actually at the begginning we were working with ports 7 and 8 for the other motors, and now we are back to it (so the M569 P7 and P8 code).

Isn't it normal that only 3 motors appear, as on the drive 2 you can have two different motors ? The total is 4 motors...

We think that the problem is linked to an update on the Firmware (in september 2019?)... The Duex is recognized but the information is not driven into the motors.

SIam

@PaulineC said in Stepper motors ports Duex5 seem to not respond anymore:

2

is it possible that you update your firmware to the latest 2.5.1 (not 3.0!) and then post the result of m122 again

PaulineC

I don't see 2.5.1 in the possibilities. We updated the firmware to 2.0 yesterday and it changed nothing :

Dougal1957

@PaulineC that doesn't update the firmware on the board please send it M115 and report the results.

oh and 2.05 is later than 2.0 and that is in the list latest is actually 2.05.1 which I believe is what @SIam meant.

2.0 by the way is now quite old.

A Former User

you'll find the firmware here
https://forum.duet3d.com/topic/14310/reprapfirmware-2-05-1-duet-2-and-1-26-1-duet-06-085-released/1?_=1581494521559

and for the configurator 2.03 to 2.05 would be the one to use after updating the firmware first.

PaulineC

@bearer Thank you yes, we downloaded the firmware from here yesterday.
I'll do the M115 command as soon as I get back to the printer in some minutes, and will update the situation.

Actually we didn't work on the firmware since june 19, so we were working with 1.21 and everything was ok. I believe now we need to update

PaulineC

Okay so did the M115 command, and even if i downloaded the file of the new firmware and put it into the sys file, but it still returns that :
Reprapfirmware for Duet2 Wifi/Ethernet Version 2.0 (RTOS) running on Duet Wifi 1.02 or later + DueX5 Board ID...

The update is in a way that I don't get, not working

A Former User

so we were working with 1.21

The update is in a way that I don't get, not working

there are a few files that have changed names along the way, so either search the forum for the details, read the whats new file or update the board using usb and bossa.

droftarts

@PaulineC Just downloading the file and putting it in the sys folder may not update the firmware. If it doesn't, you need to send command M997 S0 to install the firmware.

Ian

Dougal1957

@droftarts also hasn't the IAP File changed between 2.0 and 2.05 (not sure but I believe it has I have moved to V3 a fair while ago now).

Doug

droftarts

@Dougal1957 May have done, but will only need to update that if @PaulineC wants to downgrade back to earlier firmware from 2.05.1. We'll see if they get an error trying to update, as they were on 1.21 before, updated to 2.0.

@PaulineC For your config.g, you should define all the motors with M569 and set them for each axis with M584, before setting motor speeds and accelerations. Below is a version of your config.g done like this, without the 'Custom settings' section at the end. Also, it would be best to put motors that are on the same axis on the same board (Duet or DueX), eg M584 X0:1 Y:2 E:3, Z:5:6:7. I have not done this below.

@droftarts Thanks for the information about the M997 command, it worked perfectly fine and now we're running 2.0.5. Unfortunately, it changed nothing. I'll try using the rework of the config.g file that you just sent, thank you !

@PaulineC Can you check if the Duex is getting power at the screw terminals with a voltmeter? Check the connections; see: https://duet3d.dozuki.com/Wiki/Duex2_and_Duex5_Features#Section_Wiring

The Duet is seeing the Duex, because in the response to M115 you get:
Reprapfirmware for Duet2 Wifi/Ethernet Version 2.0 (RTOS) running on Duet Wifi 1.02 or later + DueX5 Board ID...
So it may just be a power issue. Also check jumpers on the DueX; see https://duet3d.dozuki.com/Wiki/Duex2_and_Duex5_Features#Section_Jumpers

Otherwise, please can you post a picture showing the Duet, Duex and wiring.
