First time using duet wifi, nothing working
-
To preface, or for context. I've only been 3d printing about 6 months. I've messed with firmware a bit, and I know a bit about hardware/wiring but generally not enough to understand pinouts. Most of my knowledge comes from wiring diagrams, which are what I referenced when wiring up my duet, and then I added a couple mosfets/signal wires and I'm running 2 12v PSU's, one going to the hotend and the other going to the bed.
Anyway, nothing is working. When I plug the printer in via USB, it connects via COM5, but I can't jog controls, and I can't heat my hotend or bed. I pulled out the SD and plugged it into my computer just to double check and make sure that I didn't need to install firmware, there's files in there it looks like, so I don't think that's it but correct me if I'm wrong.
Could anyone help me figure out the root of this issue? I know next to nothing about this board or the firmware, all I've basically done is wired it up, and I'm using matter control as my slicer. Anyway, any help is appreciated and if pictures are needed or any more info, let me know. Just to reiterate, the printer is connecting, the thermistors on the bed and hotend are reading ambient temps, but I can't do anything via USB. I don't have a display for it yet so this is how I've opted to print until I can get a display or figure out how to set up the wifi.
Thank you!

The reason that the jog controls don't work may be because the config.g file has configured the firmware for a delta printer, in which case movement is not permitted until the towers have all been homed.
Please explain (preferably with a diagram) how you have wired your PSUs, hot end heater and bed heater to the Duet.

So, before reading your reply I removed the mosfet hearing from the equation, I have the PSU voltage running through a mosfet and into the duet. I DID previously have signal wires wired from the mosfet signal into the hotend heater. After removing that, the hotend still does not heat but the thermistor is working properly. I did the same with the mosfet I had hooked up for the bed, instead running the voltage to the board. The bed was only able to get up to 25c and it stopped from there.
I noticed my stepper wiring may be off so i looked over the nema17 steppers wiring diagram and wired the corresponding pins to the ones to match the board. My steppers are now able to jog, HOWEVER, any movement on the x or y axis jogs the other respectively, they also take one step forward and then the same step back, so they wiggle back and forth. I assume at this point my pins are not wired correctly and the diagram I am referencing may be outdated or it's just my ignorance.
Here's the diagram I am referencing for my wiring for the record:
https://duet3d.com/wiki/Duet_WiFi_and_Ethernet_wiring_diagrams
And also what I referenced for my stepper pinouts:
The stepper wiring is as follows
Stepper motors:
Blue = 2B
Green = 2A
Red = B1
Black = A1The wiring as it appears on the board:
Blue ]
[ Green ]
[ Black ]
Red ]And I'll post pictures momentarily for your reference as well.
Also I was able to get the web interface functioning, so things are looking up, but I am concerned with the lack of voltage my hotend and bed are getting and the heating errors, and of course my potentially (most likely) faulty wiring on the steppers.Cheers.

https://ibb.co/fY4wGGPlease pardon my insanely messy wiring. I'm still getting the wiring and my build sorted, so right now I'm just trying to grasp everything that's going on, and then cleanup later.
Thanks for your quick reply and the help!
Edit: also I just noticed your mention of the delta printer. YES you are correct, when I move any axis in the web interface it mentions a delta printer, I was wondering why that is the case. Should I modify the config directly on the SD card or is there a faster way to go about doing this? (Also please still reference my other questions as I'd like to ensure my wiring is proper)
Endless thanks

I suggest you create new config and homing files using https://configurator.reprapfirmware.org/. Then you can upload the resulting zip file though the Settings/General page of the web interface.

I'll do that. Is my wiring on the steppers correct as far as you can tell?

Hi Tinino
In the configurator, you may find it helpful to make use of one of the stored configurations listed above the spot where you use existing or create new.
That will get you starting out from a cartesian perspective and not the delta configuration.
You will need to remove the macros that are intended for delta printers, but you can get to that when you're ready.

Regarding stepper motor wiring, typically, red-blue is one phase, and green-black is another phase. So the wiring order I normally use is red-blue-green-black.

Thank you sir. I'll rewire in that order and mess with the config when I get home today. I appreciate your help

I'm kinda at a loss here. The motors are still doing the same thing, just kinda stepping forward then back. My z axises move however they don't move in parallel, they move one after the other, so it jerks up like 30 degrees on one side, and then jerks up like 30 on another. When uploading the configuration I set it to Cartesian, I calculated the steps with my t8 rod with 2mm pitch, 1mm of movement is like 10. The steppers were originally wired as you described and so I moved them back, my endstops are wired NO and not NC I believe my signal wire is in the right place as well, but maybe I'm wrong? I definitely don't understand what's causing the unparralel z movement, I'm using 2 z steppers which are running off of the same stepper driver it looks like, so they shouldn't be moving separately. My hotend still refuses to heat, but the bed is heating now. I've tried wiring the hotend wires to both options for the heater, neither is working. I used a multimeter and checked the voltage on the hotend heater and it's around 12.24 bolts, but for whatever reason it's not getting a signal, the thermistor is still giving readings however. I even tried plugging in another hotend just to make sure it's not a faulty heater, and the hotend I know works still didn't heat. I'm not sure what to do at this point, and the config setup isn't too hard to use, I'm just not understanding why anything is stepping. Maybe my endstops aren't wired right, maybe I'll try flipping the wires and see how that goes. Any advice on how to address the hotend issue and any more insight on the z steppers? Thanks again for your patience and willingness to help.
Edit:
So I looked into NO sensor wiring for the duet and corrected the wiring for my switches. The black wire goes to the NO/signal on the switch and I'm running the red wire to the GND, leaving the middle voltage pin empty. The stepper motors are still doing the same thing.
I completely removed the mosfet altogether thinking perhaps there's some form of a current issue wiring the board directly to a single 12v psu. All motors still acting the same way no matter what is done with the wiring. Removing the endstops altogether doesn't even correct the issue.
I triggered the z endstops manually to check the LED's on the board, and to ensure that the end stops were all wired correctly and in the right places. Even though my z axis is super messed up, the motor direction is correct, to test I homed my z axis and the switch worked as it should, so the z stop at least is functioning correctly. X and y axis I am still unable to jog. I modified the configuration to strictly x16 stepping from x16 interpolated to x256, still the exact same issues. Both z axis motors still not moving in unison just an FYI, I reread my paragraph above and it seems to imply that. The stops work, all the motors not so much
-
Okay. So I ran the z motors in line versus using the 2 separate connections, and now they are working great. However the esteps are definitely off. 1mm of movement is more like 10, but it's progress! Progress at last! My x and y axis are still giving me a hell of a time though, I need some insight on that one. Hotend still not heating. Thanks!
-
Z axis is calibrated, got the esteps going and it's running flawlessly on the z. However my x and y motors are still jerking back and forth, I can't figure out why this is happening on those two axis. They are no different as far as wiring goes than the z axis. I still can't get my hotend to heat whatsoever. I've repeatedly tried switching between the E0 and E1 heater connectors to no avail, I can only get a thermistor reading. This is a new out of the box E3Dv6 Chimera, so it's not an old janky hotend I'm trying to use. I can't figure out why it won't heat when I select a temp on the web ui. (Or any other place for that matter)
Edit:
I hooked my hotend wires into the bed wires and sent a command to heat my bed, the hotend is now heating up along with the bed. Yet the hotend will not heat when plugged into the E0 or E1 heater connectors.
I've had the board a couple weeks but have only tried to use it with in the last couple days. I don't know an amazing amount about the board but I am questioning exactly what's going wrong with the E0 and E1 heaters.
I guess this workaround will work for now, but I still have this issue with my x and y I cannot figure out.
Nevermind, the workaround probably won't work on second thought because the hotend current will be specifically controlled with the bed. I'll keep messing with the firmware I suppose.
FINALLY got the fricken hotend to heat. That fricken was not directed towards you lol, as you can see it has just been like 8 hours. I'm glad that's finally going. Now to tackle the issue of my x and y axis, then I'm gonna take a look at my extruder motors and see if those are working ok

Want to post your config.g file?
If your motor wires are removable, you might want to swap some around to make sure you don't have a bad crimp/connection on the ones that are not working correctly.

Just checking back on the thread. I actually was just looking into that. I just took pictures of the crimps I have and was just getting ready to post them. So, coincidentally, here's my amateur crimping job:
https://ibb.co/gz8fbG

https://ibb.co/kxrYwG

https://ibb.co/mVOfbG
https://ibb.co/do5hqb
https://ibb.co/gwM0bG
https://ibb.co/ds5RGG
https://ibb.co/gbRYwGJust to make sure it WASN'T my steppers, one of my extruder motors was twisting fine, no prob at all, so I swapped the working and the non working, and the issue persisted on the non working (the one that was stuttering) so at this point it's likely my terrible wiring. I'm not great when it comes to crimping but I thought this would work, but not sure. Could you give me an example of a proper crimp or tell me if mine look messed up?
Edit: config.g on its way, keep in mind I'm still calibrating esteps and acceleration on the stepper motors, this is the latest version (#17) of my configs. Just trying to get the hardware going so I can calibrate. I'm thinking it's my wiring that's the issue, but obviously I can't be 100% on that.

Easy way to check the connections is to hold two of the wires together and try moving the motor. So, hold the Red and Black together and try moving the motor, Do the same with Blue and Green. If the motor is a little harder to move, then you know the connection is good. If easy like it is without any wires touching, then you know you have a bad crimp.

And I can do this without the printer being on I take it? I'll test it out tomorrow. It's getting late but I think that's a good start to testing my crimps. Cheers.

To do this test, unplug the motor from the Duet. Push a short piece of solid core wire into 2 of the connections in the socket to short them.

I think I must have a bad stepper driver on my x axis. I fixed my y, my z works as well, but my x refuses to function, it's doing the same thing as before. I checked my crimps, I even tried a new wire, and another new stepper I had lying around, it's just not functioning. My endstops seem to be wired correctly, as they all work. My wires work, my motors work, my crimps are fixed, my cables are good, so the only thing I feel it's rooted to at this point is maybe somehow my x endstop is triggering, or it's a bad stepper driver. Any other ideas for troubleshooting my x axis? I feel like I've tried it all at this point.
Thank you both for taking your time with this

I did another test. When swapping a motor that was just previously working (y axis) over to my x axis, the y stepper motor produced the same issue, while the x axis worked fine. Both stepper motors work, both cables work (didn't change the cables I used just swapped the connections on the board). Y axis now jiggling, x axis works fine. What could be causing this? I really hope it's not a bad driver. I have no clue what the issue is.
Edit: changing the ma values in the config didn't work either. Increased it slightly but at that point the motor didn't even move. Put it back down to 800ma, it's just back to jiggling again.
I uploaded a config where I changed the endstops to NC from NO, unplugged all the end stops and turned it on, tried jogging the motor, same results, just jiggling rapidly back and forth.

If your E1 motor output is free, try putting this command in config.g:
M584 X4 Y1 Z2 E3
Make sure it is earlier in the file than the M906 command. Then connect your X motor to the E1 motor output.
If that gets your X axis working, then I'm sorry you do have a bad X driver, and you should ask for your Duet to be replaced or repaired under warranty.
Are you using 12V or 24V power?
