Help needed with Duet 3 6hc TMC5160 StealthChop config
-
I'm sorry for the delay. This is still on my list to continue investigating. As it's a noise issue not a functionality issue, it has lower priotity then some others on my list.
-
Hello! The same thing on my CoreXY using Duet3. Does anyone have found a solution?
-
no sorry
-
My suspicion is that the issue is not following the tuning sequence specified by Trinamic. In particular, you are supposed to energise the motors, keep them still for a short while (but less than 130ms), then execute a medium speed move such as a homing move. Here is an extract from the datasheet:
Typically, homeall.g does something like this:
G91
G1 H2 Z5 Fxxx
G1 H1 X-400 Fxxx
...The initial pause at standstill is after powering up the motors is not present. So perhaps this would be better:
G91
G1 H2 Z0.02 Fxxx
G4 P50
G1 H2 Z5
G1 H2 X0.02 Fxxx
G4 P50
G2 H1 X-400Similarly for Y. The 0.02mm figure should be adjusted so that it is at least one microstep, but preferably not much more than that.

it looks like it does not help, I have created the following test macro file, but I can´t hear any difference only on still stand after moves I can hear the motors a little bit when Spread cycle (D2) is enabled.

I have also to reply here.
I have Moon Motors.
I think even the same as you. Need to check in detail, but i think so.I starte with a Duet Wifi clone and they were really noise in some higher speed (>70mm/s)
So i decided to go for the Duet3 and the advanced TMC5160, as noise is key for my MGN cube. (CoreXY)
In fact now, if i switch to stealthchop, it is even "noisier" than in spreadcycle.
No such a "high" noise, but louder....I am lost now...
-
i am having also the Problem, that I am not able to bring my stepper noise down, and I do not find any way to solve this.
Tried mechanicly already a lot of things, 3 different stepper Motor types, but all with more or less the same noise.
The are damn loud.
Was your issue solved?I also find in the documentation this:
Vnnn (firmware 2.02RC1 and later) tpwmthrs parameter for those stepper driver chips that support it. This is the interval in clock cycles between 1/256 microsteps below which the drivers will switch from stealthChop to to spreadCycle mode. Only applies when the driver is configured in stealthChop mode. Typical value are from 100 (high speed) to 4000 (low speed). Send M569 P# (where # is the driver number) with no additional parameters to see how this translates into mm/sec.Values below 100, are not a Problem and get correct configured?

Have you seen this thread https://forum.duet3d.com/topic/18010/duet-3-stealthchop-2-tuning-for-nema23 ? The author of that thread was able to use stealthChop to quieten the motors, until the speed reached the value at which there was insufficient drive voltage for the motors.
-
Hey man I just noticed I had this lines in my config.g here for my sensorless homing;
it seems like Stealthchop would not engage unless these are in place
; Stealthchop parameters M915 P0 S3 F1 H134 T1 R0 M915 P1 S3 F1 H134 T1 R0I do not not why, but my guess would be around T parameter that controls the coolstep register according to https://duet3d.dozuki.com/Wiki/Gcode#Section_M915_Configure_motor_stall_detection
Edit: Also the Hmin parameter; for which I made a calculator here:

@fractalengineer
Can you post your full motor related config.
My motors are extremly noisy on my MGN Cube.
I DIsassembled everything the last 2 days, and reassembled the full frame, and it is still 100% the same.When i switch beteen spreadcycle and stealthchop, i can not hear any difference, and i dont know why...
-
@fractalengineer
you mean I have to configure motor stall detection to get Stealthchop running?
This I have never tried,What I do not understand what T1 means
is this TCOOLTHRS?TCOOLTHRS ≥ TSTEP ≥ THIGH:
- CoolStep is enabled, if configured
- StealthChop voltage PWM mode is disabled
@empi00 I think the problem is that the vibration comes from the motors for a temporary solution I have add some Stepper damper to the X/Y Motors that has helped a lot. But you can still feel the vibration on the Motors with the hand, this will not fix the vibration problem it is only a "not so nice" work around.
and I was hoping that @dc42 will find the problem. My feeling was that stealthchoop is enabled but only up to F119 (that is verry slow) on F120 I had strange noices like it is jumping between steahltchop and spreadcycle. and F121 is noisy like only spreadcycle. When no motors are moving all is fine then spreadcycle (D2) is more noisy as steahltchop (D3).
Any M569 V and H parameters does nothing here for me.
The funny thing is when I use a other board with TMC5160 and klipper it was working, so I´m pretty sure it is not a hardware issue.
When I have time I and I have understand what the T parameter is doing on M915 I will play with. -
Well,
i will post my story tommorow.
I was building a BLV MGN Cube.
https://www.blvprojects.com/blv-mgn-cube-3d-printerStarting point:
Duet2 Wifi clone with Moon motors.
Terrible loud noise.
Running with 27 Volts.- tried different current. Lower current are "better" but still very loud.
- I bought than the Ferrari, a Duet3 original with TMC 5660.
--> Not improvement, but i am not sure of stealchop is running well - I bough in total 4 different stepper types with different cables. Different noise frequencies but still very loud (Stepper Online 1,8 + 0,9, Sunsomething 1,8 degree, Moon 0,9 degree)
- Dampers made it dead silent, but the steppers were bending. The design has also a bearing to help the stepper shafts on staibility and they are not possible anymore. This would be my last wished solution. (Expecially as this built was made by many people, and other seems to have this not problem.)
- Disassembled the full frame the last 4 days. Filled the profiles with sand and epoxy, to improve the vibration damping.
Though that i made maybe something wring.
You can shake now the profile (without electronics) and you hear nothing. (no "lost" nut or anything)
AND:
Still the same noise....Ordered just right now a SKR 1.4 Turbo with TMC2209 and see how this goes.
I really like the Duet in general, especially from the usability.
But honestly, I would expect from the software a "easier" enabeling from Stealthchop, as it seem that something is not easy here.I am still searching for the "guilty" think in my case.
- Steppers, closed, as all 4 types have the same problem
- "Electronic noise". closed, as dampers are helping
- Defect TMCs, shitty Duet2 Clone,... closed, as I have now a Duet 3 with the same Problem
First of all, I just want to figure that "guilites" out.
So I want a way, just to enable stealchop for 100% and nothing else, to see if it helps.
But even that seems not to be so easy.I am somehow lost....

Got it; ok so there are a few things I've learned:
-There is some info on the RRF Gcode page, but it's still pretty vague so if you're gonna be pioneering there is more in the Trinamic 5160 datasheet.
-The default M569 V parameter is pretty high; it controls from what speed the driver switches from StealchC to SpreadC. Like 15mm/s iirc. Lowering it will enable SleathC to run at higher speeds. Check my config down below.
-You must also implement a proper calibration sequence in your homing files; it's detailed in the datasheet but @dc42 broke it down well some posts above
-Then if you still can't hear a difference try that M915 line I included above; which seems to enable it but for the life of me I can't understand how lol
-By now you can try running it at low speed and switching between M569 D2 and D3 (I made macros that include both lines for both X/Y steppers) to hear whether it's working
And it should be rather noticeable; StealthC sounds more like a humm rather than the Bzzz in SpreadC lol
Last thing, when switching from D2 to D3 there is a jump that is expected; it's in the datasheet
That's it I just dumped about all I know on this occult topic haha; it's still not running exactly as I wish and that's the thread Dc was referring to, but this made me progress a lot

@fractalengineer
So it means that Stealthchop is active on x/y till 70mm/sec ? -
@Touchthebitum said in Help needed with Duet 3 6hc TMC5160 StealthChop config:
@fractalengineer
So it means that Stealthchop is active on x/y till 70mm/sec ?Depends on your config; steps/mm, microstepping.
You're supposed to enter a V value then check it in the console by entering
M569 Pxwithout anything else. It will return the complete config with actual belt speedsV value is the speed at which the mode switches from Stealthchop to SpreadC
H value is the speed at which it switches to Full step -
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 0, tpwmthrs 130 (28.8 mm/sec), thigh 50 (75.0 mm/sec)
I have this result, does it seem correct ?
-
Ok so what you can see here is "tpwmthrs 130" means your M569 V parameter is 130, meaning is will only run Stealthchop up to 28.8mm/sec
-
@fractalengineer
ok ,thanks -
@empi00
your storry is particle also my Storry
I have started with a Tevo Tornado Gold, steppers are loud, this machine has a MKS Gen L V1.0 Board so I replaced the drivers with TMC2800, installed Klipper and used Repetier Server as frontend on the raspberry.
I was amazed, the steppers you can not hear anymore when the machine is printing, on quick moves the drivers use SpreadCycle and you can hear the differnces.
So I was really happy with the machine, but I would have more speed.Then I started to build the BLV with the new BTT SKR Pro 1.1 with TMC5160 sound was ok but regarding the new Type of printer it was louder as the Tevo, this is clear regarding the MGN Hiwin Rails.
But I had sometimes the problem that I lost a stepper after a while of printing (now I know it is a Hardware defect on the board, first driver sockel gets disconnect when the machine gets warm so I think it is a solder problem).
So I decided to try a Duet Wifi clone, but I had not read the full documentation so I missed that stealthchop is not availabe.
I was chocked how loud the machine can be with the 2660 drivers, but the machine was stable.
Then the Duet 3 comes out with TMC5160 and direct connection to a raspberry.
So I was hoping I can get all my wisches now.
But the noise of the printer is nearly the same, only when the steppers are not moving you can hear a difference
I have tested the motors alone, not build in to the printer and you can feel the vibration of the motors when a duet board is
connected.
When I connect a different board like the SKR Pro or now the GTR with TMC5160 and Klipper installed the motors are smoother on the same speed etc.
I have two ideas what can be behind.As first Klipper/Marlin etc. use for the SenseResistor 0.075 and the duet Firmware use 0.050 this means that you can use motors with higher current on a duetboard but I think this change also the wave so that the sound that the motors creating
are different and maybe louder is normal and it can be changed only when we get a option in the firmware to select as example 0.075 with the correct wave like all other firmware does. But I have not enough knowledge and measuring devices
for checking and testing. So it can be that I´m on the wrong way at all here.As second what I do not understand is why is there a big noice change between the speed 119mm/min and 121mm/min on 0.9° motors.
When you check my first post you can see that M569 say´s the change should be at 110.3 mm/sec
and @dc42 had confirmed that my settings are correct.
I have tried many different homing scripts but nothing changed.
at the moment I´m a little bit frustrated at all.
what I would wish for the best Board and firmware:- the gui from Repetierserver on a local touchscreen (sorry but the gui from the duet does not really work for a touchscreen, but is not so bad on the browser. The preview of the print model is missing at all on the duet)
- a mix of the config from Klipper and reprep (the settings for the TMC´s are to complicated like the threshold for stealthchop, the firmware has all information to calculate it from stepper speed like klipper and marlin does)
- the hardware from duet 3 with the direct connection between Raspberry and the board. I like when I stop / pause a print it does directly. On Klipper the printer has a buffer so it pause and cancel when the buffer is empty and not directly.
Sorry for the long text but I have the feeling it goes not forward since month. I understand that Duet3d must look for business and creating new things but it would be helpfull to have all functions that are promised are also correct working
before new things are started. -
I think many people mainly buyed this Duet3 for this Stealthchop feature. It is a pity we can't use because it is a great improvement on noise.
I saw some videos and the difference is huge.
