Help needed with Duet 3 6hc TMC5160 StealthChop config



  • Hello I´m trying to switch the board from a SKR Pro 1.1 with TMC5160 (X&Y) used with klipper.
    with klipper stealthChop works fine with 100mm/sec.
    When I now try to use the Duet 3 with stealthChop it looks like stealthChop work only up to 119 mm/min
    when I use a move command like G0 X100 F119, it is verry slow but nothing to hear like on the SKR with klipper.
    when I use a move command like G0 X100 F120, i have a strange noise/klicker and over F121 it looks like the drivers goes to spreadcycle.

    can some one point me in the right direction what I´m doing wrong or what I have overlooked?
    Stepper Motors:
    X/Y: Moons MS17HA6P4200-06, 0.9deg 56Ncm 2A
    Z1/Z2: 42BYGHW811, 1.8deg 48Ncm 2.5A
    E: 17HD40005-228, 1.8deg ??Ncm 1,5A

    at the moment I use the board standalone.
    my System Informations:
    Board: Duet 3 MB6HC (MB6HC)
    Firmware: RepRapFirmware for Duet 3 MB6HC 3.01-RC12 (2020-05-06b1)

  • Do you realize the speeds are in mm/min?
    So F119 is very slow



  • yes like I wrote.
    all above 119mm/min goes to spreadcycle 😠
    also with V34 (110mm/s) parameter in M569.
    and I can not understand why, it looks like the V parameter does not realy change the tpwmthrs.
    but when I check this with m569 P0 as example it gives me
    Drive 0 runs in reverse, active low enable, step timing fast, mode stealthChop, ccr 0x08053, toff 3, tblank 1, hstart/hend/hdec 5/0/0, pos 56, tpwmthrs 34 (110.3 mm/sec) , thigh 200 (18.8 mm/sec)
    so it sould be on 110mm/sec and not 2mm (120mm/min) /sec
    I have still not understand what the H parameter (thigh 200 (18.8 mm/sec)) means 😞 maby someone can explain it.
    I have tried higher H and lover H parameter nothing changed for me.
    when I search for "stealthchop" in the Forum it looks like some others has the same problem, but not found a solution for.



  • has some bring StealthChop running on a Duet 3?
    when I search here in the forum it looks like only problems with a maestro was fixed the issues with the duet 3 looks all
    still open.
    has someone the maestro running with RR 3?
    @dc42 do you have some tips that I can try or what is wrong with my configuration?


  • administrators

    I am not aware of any bugs in this area, but have added this to my list of things to test prior to the 3.01 release of RRF.



  • @dc42 this means I have nothing wrong in my config? 😧
    I was hoping that I have done something wrong.


  • administrators

    I don't see anything wrong with your config, and M569 P0 says the threshold speed for changing to spreadCycle should be around 110mm/sec. That speed won't be exactly right because it depends on the accuracy of the 12MHz clock in the TMC5160.



  • @dc42 ok then I have to wait for your tests and hope we can find a solution.
    let me know when I can help here with testing etc.


  • administrators

    From my reading of the datasheet, you should always have THIGH < TPWMTHRS. Have you tried setting THIGH to values below 34?



  • @dc42 said in Help needed with Duet 3 6hc TMC5160 StealthChop config:

    THIGH

    I think I had done is the H parameter right?
    I will try again.

    Yes. Use M569 with just a P parameter to check that you have set it.



  • @dc42 I have tried with H10 for X and Y achses (P0.0 and P0.1) nothing changed, StealthChop only works below F119 all above only Spreadcycle from the noise.

    M569 P0.0
    Drive 0 runs in reverse, active low enable, step timing fast, mode stealthChop, ccr 0x08053, toff 3, tblank 1, hstart/hend/hdec 5/0/0, pos 548, tpwmthrs 34 (110.3 mm/sec), thigh 10 (375.0 mm/sec)
    M569 P0.1
    Drive 1 runs in reverse, active low enable, step timing fast, mode stealthChop, ccr 0x08053, toff 3, tblank 1, hstart/hend/hdec 5/0/0, pos 884, tpwmthrs 34 (110.3 mm/sec), thigh 10 (375.0 mm/sec)
    

    to be sure also tested :

    ; Drives
    M569 P0.0 S0 D3 V34 H50                            ; physical drive 0 goes forwards D2=Spread cycle (x-achses)
    M569 P0.1 S0 D3 V34 H50                            ; physical drive 1 goes forwards D2=Spread cycle (y-achses)
    
    13.5.2020, 22:17:07 	M569 P0.1
    Drive 1 runs in reverse, active low enable, step timing fast, mode stealthChop, ccr 0x08053, toff 3, tblank 1, hstart/hend/hdec 5/0/0, pos 972, tpwmthrs 34 (110.3 mm/sec), thigh 50 (75.0 mm/sec)
    13.5.2020, 22:17:01 	M569 P0.0
    Drive 0 runs in reverse, active low enable, step timing fast, mode stealthChop, ccr 0x08053, toff 3, tblank 1, hstart/hend/hdec 5/0/0, pos 540, tpwmthrs 34 (110.3 mm/sec), thigh 50 (75.0 mm/sec)
    13.5.2020, 22:16:07 	G0 X130 Y130 F90
    13.5.2020, 22:15:51 	G0 X135 Y135 F90
    

    now also G0 X130 Y130 F90 runs only in SpreadCycle



  • @dc42 was you able to test?
    I have also tried to change the D settings on a test print to hear some changes, but nearly nothing has changed only on D0 (constant off-time)
    he goes a little bit louder but not much. D1 (random off-time) is not supported by TMC5160.
    can it be that my board is faulty or that the Firmware has a Bug and only shows the corect mode but not send to the stepper drivers?



  • I have seen the source code "/src/Movement/StepperDrivers/TMC51xx.cpp"

    constexpr float SenseResistor = 0.050;
    

    when I right on other firmware´s I use 0.075, can this create a difference?
    Is it possible to play with over the M569 command or is it needed to compile new, have not found in the Duet documentation.



  • I'm experiencing the same thing @danym21.
