Help needed - Installing Duet 3D 6HC in replacement of a SKR 1.4



  • Hi evryone,

    I'm new to the Duet3D world and it's firmware, I have an Ender 5 Plus and a Artillery Sidewinder X1.

    The Ender 5 has been running on a SKR 1.4 with TMC5160 drivers for most of the year now and I have a Duet3 6hc motherboard that has been laying around for about 3 months now as I've hear some many good thing about the hardware and the software but never got around to install it but now the time has come.

    Now being a completely noobs on this hardware and software, I want to make sure I'm doing things the right way so I don't kill the motherboard, I see that a more detailed wiring documentation is yet to come regardless I think I've figure most of the cabling but I do have some questions just to confirm I'm doing things the right way as the Duet3 6hc seems to be way different from the other Duet cards; I apologize if some of my questions seem silly but as said I'm a complete noob on this hardware:

    1- Is there a particular way to plug the stepper motors on to the board?

    2- The endpoint sensors are meant to be plug on the IO_X section of the board as well as the BL Touch?

    3- Temp_X is where the thermistors should be plugged in?

    4- where should I be plugin the fans for the board, the hot-end and the pieces being printed?

    5- Is there a particular way to plug a Paneldue on this motherboard?

    6- As the Ender 5 plus has dual Z motors how do you define that on the web configuration tool as I've only been able to add a second extruder(E1) but not and additional motor (Z1)?

    7- A finally, is there anything that needs to be set in the confiuguration tool when using a direct drive?

    Again apologies if my questions are silly but as said, I just want to get things right and not blow up the card and I'm yet to find out if it has the shortage issue.

    Thanks in advance for any response that you would provide to get me on the right path and complete the installation without any issues it would be highly appreciated.

    @aldiallo welcome on board!

    have you seen the wiring diagram here:
    https://duet3d.dozuki.com/Wiki/Duet_3_Mainboard_6HC_Wiring_Diagram#Section_Revision_1_0_and_1_Num_01

    1. The motors should be wired with the coils in pairs, so 1 coil on pin 1 and 2, with the other pair on pin 3 and 4. This is fairly standard but since you have to re-terminate the cbales with the JST plugs you can make 100% sure with a multimeter. The motors will have a low resistance between two wires on the same coild and no connection between wirtes on different coils.

    2. Yes, endstops are wired to the IO headers as well as the BL touch. The BL touch needs to go to a IO connector with PWM capability. This is listed on the hardware overview page: https://duet3d.dozuki.com/Wiki/Duet_3_Mainboard_6HC_Hardware_Overview#Section_IO so IO_4,5 and 7 for PWM out.

    3. Yes, you will define which thermistor maps to which heater as part of the config

    4. There are two banks of low current outputs that are suitable for fans. OUT_4,5,6 make it easy to connect 3 or 4 wire fans (although two wire cans can be connected) and OUT_7,8,9 are for 2 wire fans. Each of those banks can be set to either VIN or 12V depending on what your fans need.

    5. the easiest way is to plug it into the panelDue header with a ribbon cable. you can also plug it into IO_0 with the 4 wire cable

    6. The config tool does not have multiple Z motors as an option yet. Just set it up for 1 Z motor and use the M584 command to add the second motor in config.g

    7. there is nothing specific to a direct drive extruder vs a bowden extruder. set the correct steps/mm etc



  • Many thanks for the prompt response, I now have what I need to start working on the wiring.

    Thnaks again T3P3Tony.



  • Hello,

    I've began my wiring, I forgot to ask about the filament sensor wiring, I'm assuming that is also to be wired to the IO_X section and declared on the config tool, correct??

    Thanks in advance



  • Ok, now after a few hours, I've completed the wiring and I've plug turned on the board, mus admit that I'm a bit confused.

    I've managed to load the config file I downloaded from the configurator website and that seems to have load correctly, that been said, I'm getting some errors:

    G28: Error failed to enable endstops, also: Error: Heater 0 fault: temperature rising much more slowly than the expected 1.8°C/sec, and also this one: Warning: 12V under-voltage event (9.5V)

    I guess this is due to bad cabling on my side, so trying to troubleshoot.

    I also ran teh M584 command and got this on the console window but not seeing them :
    M584
    Driver assignments: X0.0 Y0.1 Z0.2 E0.4, 3 axes visible

    any ideas?

    thanks



  • @aldiallo some photos of your board cabling and the config.g will help us troubleshoot (-:



  • Hi @oliof,

    G31 P500 X0 Y0 Z2.5 ; set Z probe trigger value, offset and trigger height

    this is missing the offset of the probe

    did you swap temp1 and 0? is this on purpose?
    B4138 is the default and must be adjusted for your thermistors used.

  • You need to provide power in to the OUT 0 power in to be able to use OUT 0



  • Hi @Veti

    Concerning the BLTouch, that's strange as I set it to the default 2,5 mm.

    Concerning temp0 and temp1, I have the bed thermistor on temp1 and the hot-end on temp0; should it be the other way around?

    I'm using the stock ender 5 plus thermistors, I believe that in the case of the hot-end it should be a 100k one from I've found in the web, but no clue on what value to use for the bed, should I be using the same as the hot-end?

    thanks



  • Hi @jay_s_uk,

    Oh, ok, I thought that the bed will be taking automatically power from the power in and feed OUT 0.

    thanks

    you position of the bltouch is the same as the nozzle, this is physical impossible. you need to change the x and y value

    ok just checking that is was done on purpose

    try the values from the ender 3
    https://duet3d.dozuki.com/Guide/Ender+3+Pro+and+Duet+Maestro+Guide+Part+2:+Configuration/38
    Set the values for both Thermistor values as: R25 – 98801, B – 4185

    Sorry, I got you wrong, the 2,5 mm I was reffering was the trigger height which I left at default, I'll go ahead an make the changes to the X and Y offset, thanks

    Will check that, thanks, will also refer back to the marlin config, which I should have done in the first place

    thanks again



  • Hi everyone,

    Making some progress here, manage to get a few things working but others are not working properly or not working at all.

    X and Y homing ok but on the Z axis I only have one motor working, I did used the M584 command as advised but is not seem to be taking it into account, so when I try to home Z, I must do the 2nd motor manually; this is what I sent as command: M584 X0 Y1 Z2:3 E4

    The Bed is not heating, I guess the wiring is not correct; not sure how it should be done on this board, I previously had cable the 2 cables going to the bed to the out 0 but that wasn't work so moved the cable to the out 0 Power In, but I still have the issue.

    I'm also getting this error and not sure what's causing it: Warning: 12V under-voltage event (9.4V), might be related to the bed not heating up issue.

    Have 3 fans, one for the board on out 4 working fine but the other 2 on Out 7 and 8 for the part cooling fan and the Hot end fan, both are turning, but this I assume is due to the temperature not being reached.

    Also, where should the filament runout sensor should be plugged and how must one go to declare it as such? I'm guessing that the IO_x ports are my best bet.

    Here's my config.g file, please let me know what errors do you see that I'm overlooking, thanks

    Try Z0.2:0.3 to match the syntax of the other drivers.

    Also please send M98 P"config.g" to see if you have any other configuration error messages.

    Also provide the results of M122.

  • Ok, so the issue with the 2nd Z motor is sorted, thanks Phaedrux!

    now need to sort out the Bed heating issue as well as the fans, the undervoltage warning and figure out how the filament runout sensor should be wired.

    I'm really impressed on how smooth and silently the motors are moving compared to my previous skr board; once I managed to work my head around all of this, I might order another board for my Sidewinder X1

    RepRapFirmware for Duet 3 MB6HC version 3.01-RC9 running on Duet 3 MB6HC v1.01 or later

    First step will be to update your firmware to 3.1.1

    Upload this zip file as is (don't extract it) to the /system folder via DWC.

    https://github.com/Duet3D/RepRapFirmware/releases/download/3.1.1/Duet2and3Firmware-3.1.1.zip

    then we need some more info on your hardware.
    What kind of endstops are they? How are they wired?
    What kind of filament sensor is it? It would be wired to an io pin as well.

    Heaters should be PID auto tuned to give the firmware a model of their performance. That will solve the not heating fast enough error.

    When does the under voltage event occur?



  • Hi Phaedrux,

    Ok, will do the update now, concerning the hardware, is just the stock hardware for an Ender 5 plus, yes the endstops are wired, same thing for the filament sensor is the stock on and yes also wired, I have it connected to the IO_2.

    Shouldn't I be doing the PID auto tune once both (hot-end and bed) are heating properly?

    My issue seems to be wire related, you can see on the pic below that the 2 thin cables going out of the mofset where plugged on my previous board and provided electricity to the bead to heat up, now on the new board, it seems that it should not be plugged that way, please note that currently the cables are plug into OUT 0

    bed wiring

    concerning the under voltage, I'll make some other tests and revert back

    I would abandon the creality mosfet and use the Duet 3 to power the bed directly as it's rated to 15a. Keep in mind that the bed heater ports on the Duet (out0) are powered from the adjacent out0_in ports which should get power directly from the PSU or be bridged from the VIN.

    6-way barrier strip: two pins for main VIN and GND; two pins for the VIN and GND supply for the OUT_0 terminals; and positive and negative OUT_0 terminals. OUT_0 is intended to drive a bed heater. The ground side of OUT_0 is switched by the mosfet and the positive side is protected by a 15A fuse. If using the OUT0 terminal to drive a SSR, take note that their polarity is opposite to the polarity of the VIN terminals.

    That may be why your bed isn't heating at all. From you photo it looks like you don't have power going to out0_in.

    If the filament sensor is just a simple switch for filament presence detection you can check out the M591 command.

    Which ever io port you connect the filament sensor to would be used in the C parameter of M591.



  • Ok so you recommend to remove the mofset completely, correct?

    Ok I'll work on that tomorrow, any way I'm swapping the power unit so will do that then

    Yes the filament sensor, is just simple switch for filament presence, I might change that in the future with something a little more feature rich.

    Tried updating the firmware but no luck, it starts loading the files but never seem to stop, it gets to file 6/18 and then it just keeps uploading without saying what or stopping.

    Correct. I'd trust the Duet 3 more than anything Creality has ever produced and if you're using the stock ender 5 bed the Duet 3 is more than up to the task.

    In that case please try this method of updating as you may be missing a few files.

  • Got the board up to date on 3.1.1 now, thanks.

    went on a removed the mofset and cable the bed wires but still not luck as I'm getting the error below:

    Error: Heater 0 fault: temperature rising much more slowly than the expected 1.7°C/sec

    OUT0 Power in is is now directly connected to the psu and the bed is wired directly to OUT 0
