Duet 2 WiFi - Config Issues or bad board? Belt Printer

KnightBelt

First, if you are reading this thanks for your interest. I am running into some head scratching issues. I am building a White Knight belt printer. Using the following equipment:

Board: Duet 2 WiFi (2WiFi)
Firmware: RepRapFirmware for Duet 2 WiFi/Ethernet 3.4.5 (2022-11-30)
Duet WiFi Server Version: 1.26
Duet Web Control 3.4.5
PANELDUE 7I using PanelDue firmware version 3.5.0

X&Y Stepper:
LDO High Temp Stepper Motor - Nema 17 - 42STH48-1684MAH

Z stepper:
Nicedea Nema 17 Motor Stepper Motor 17 Geared 1.8 Degree 42 Motor Low Noise Stepper Motor Gear Ratio 1:5.18

Hotend:
Phaetus Rapido UHF Plus (PT1000))

Extruder:
Orbiter v2.0 - 1.8-36mm LDO-36STH20-1004AHG(XH)

Heatbed:
Silicon Bed w/ PT1000 ; seams the only thing that works without issue

Fans:
Noctua NF-A4x10 FLX

I have searched the boards and have not found anything that would address the following issues. The board is mounted and isolated, The board was new in box and bought this year. While extremely rare, I am open to the idea it may be a board issue. But I am hoping it is a config issue.

Again thank you for your help with this. Let me know what else I can provide if any is needed.

Issues:

X output on the board is not sending a proper signal to the stepper. The stepper moves jerky,/pulsing, and rough. This happens when any stepper is plugged into the X port on the board.
The Y & Z stepper work just fine.
Note: have plugged additional steppers into the board directly and the results are the same. It does appear to be the signal coming out of the X port is the issue.
Update - no longer sees hotend or temp, dashboard indicates NA. -----Hotend is sometimes registered on the dashboard and not other times. The is no consistency of why, power off/on or resetting makes no difference. Very exciting when the temp shows up and is correct. Then very disappointing that it just disappears. Never does it send power to the hotend. Get the error fault of not increasing temp over the right time. I have these issues with the hotend connected directly to the board to eliminate any wiring issues.
Fans do not have power. There is no power on the “always on” or through

* PANELDUE 7I gets updates such as control/move distances that come from the DWC. It does not home or move the steppers while the DWC does. Solved thanks @jay_s_uk ; firmware updated solved issue

Other positive things:
All the power LED light up as expected
All Fuses are good
Wifi works
USB works and no issues with YAT
24v into board OK

@KnightBelt if there's no power to the always on fans, make sure the jumpers are correctly in place to set the voltage.
For X sounds like you have a damaged stepper driver.
Update your WiFi firmware to 1.27 and your paneldue firmware to 3.4.5

KnightBelt

@jay_s_uk
Thanks, Panel now can control, though I lost my Z move option, as in it no longer shows on the panel Move menu. All other issues are still in place.
BTW - Fan jumper set to VIN

jay_s_uk

@KnightBelt can you post an output of M122 after an X move and the output of M98 P"config.g"

KnightBelt

@jay_s_uk

Here you go and thanks for the interest. I do not know was a bad grid definition is.....

M98 P"config.g"

@KnightBelt if you're sure that each motor does the same when connected to X but work fine when connected to another driver then I would say that the X driver is damaged and would need to be replaced.

Theres also no need to null anything in your config so this line isn't needed

M574 Z1 S1 P"null"

Its also nil and not null

The always on fans get their voltage from here

so i would be checking that fuse again.

KnightBelt

@jay_s_uk

I do have the jumper set that way. See attached photos. I am very much leaning towards that there is a board problem. As some functions work just fine while others don't. I think it is time to start the RMA process. As there has been no other Aha!! moments.

Thanks for your help on this.

KnightBelt

Needing to get this addressed. How do I get an administrator or a moderator to engage on this thread?

@KnightBelt @Phaedrux

jay_s_uk

@KnightBelt btw, when and where was it purchased?

KnightBelt

@jay_s_uk
on 3DMakerWorld Inc. through Amazon Dec 15th, 2022. Came out of the box to this machine last month (May). I have contacted them and they are waiting for this process.

Phaedrux

Please send an email to warranty@duet3d.com and CC your reseller. Include a link to this forum thread and the details of your original purchase. You'll receive a reply with a form to fill out.

@Phaedrux

Thank you for your quick response

@KnightBelt I can see slivers of metal on some of the pictures, eg on the top of the main microcontroller, and something on one of the 3.3V regulator pins. I suggest you disconnect everything from the board, remove the board from its housing, and give it a thorough clean. Then reassemble, checking there is enough clearance behind the board that nothing is shorting out behind, and test each connection as you connect it, starting with the X stepper. You also seem to have bent/broken off some of the connector tabs?

@droftarts

You definitely got my attention and got me out from behind my desk. Was hoping for that Aha moment. I just took the board and used canned air over a black piece of paper. What you see is white and red (it looks orange) shavings and possibly a hair. The board sits in a PLA+ tray (three parts, red, white, and orange as it is a long tray) that has a tendency to make these shavings that you see when I take out and put it in. The board is completely isolated, and the bottom rests on the PLA+ only on the edges with no contact on solder points. The items you pointed out are PLA+. I know the Duet is a solid product so I would be OK with the problem being between the chair and the keyboard. As long as I knew what it is and learn from it.

As for the connector tabs, nothing is broken, bent yes. Direct plugging a fan in bent them out a bit. They still lock a KK connector in.

Thank you for your help and for pointing out that I need to address this issue as I don't want plastic shavings everywhere.

droftarts

@KnightBelt These are the sorts of bits I saw:
Screenshot 2023-06-13 at 21.00.59.png
If they are just bits of plastic, then that shouldn't hurt, but some look a bit more metallic. If you've blown it off with compressed air and still no improvement, I'd say follow through on the warranty replacement.

In the picture of the back of the board, the light is shining on the soldered pins of the X driver, do they look properly soldered?

@droftarts
From left to right the first two are Orange DuraMic PLA Plus and the third arrow is pointing to White Esun PLA+. Board is reinstalled. Taking it out (for a walk and cleaning) unfortunately did not solve the issue. Thanks again for pointing this out, without your keen eye and me blowing it on to a clean catch sheet I would have most likely not caught this.
