A few problems after setting up board... Includng stepper sounds

[nmsmith89]

Hi! After setting up my Duet 3 Mini there's been a few problems I can't seem to get past...

1. The steppers all seem to be really screechy and choppy. It seems to happen despite what the motor current settings are. (Tried 600 - 1000 mA) Higher speeds are slightly better but still terrible. I know there must be something wrong because I can very easily stop the Z screws with two fingers.

2. I have a 24v PSU hooked up via a relay. When I first booted the board I could control it. (I put an M80 in the config so the board can see the toolboard on boot) But now after updating the firmware on everything I can't control it with M80/M81 its just always on.

3. After running PID tuning on the bed and hotend (the bed was giving a slow heating fault). Both heaters now give me an "overpowered" error on boot.

Update

I figured out the stepper driver problem. (sort of) It turns out the default threshold for SpreadCycle is 4.3 mm/s which I though was kind of weird.

So now the motors are quiet if I stay in StealthChop but SpreadCycle is still really loud. To me at least, it doesn't sound right. So idk what to do about that.

If anyone has some M569 or M915 numbers for the TMC2209 to use as a starting point that would be great!

By tool board do you mean raspberry pi, or do you mean an actual tool board?

This is normal. It's telling you what it calculates the potential max temperature would be in a runaway heater situation. It's a warning.

There's some bug fixing going on with the mini5 drivers at the moment so might want to follow in that thread to see if you're seeing something similar. At the end of that thread there is a test firmware build you might want to try.

[nmsmith89]

@phaedrux

Thanks for the links!

Yeah I mean Toolboard 1LC but I am also running in SBC mode.

I pretty much set the steppers to stay in StealthChop and I also got homing working. But, for some reason the BLTouch is constantly flashing red when not being used. It also looks a little different than the normal BLTouch error flashing.

That isn't right. What stepper motors are you using, what current are you running them at, and what VIN voltage?

[Luke'sLaboratory]

@dc42

I'll add to some of this as well:

I've dug around in the source code, but still definitely have some questions on motor noise - spreadcycle on my d3 is significantly louder than spreadcycle on my skr mini, both with 24v, both with the same motors.

Is there any config in particular thats recommended for the trinamic settings for the 2209's? Any unique things designed into the circuitry that deviate from the norm as well?

I remember from a seperate thread that the voltage is actually capping the current delivered and that might generate noise, is that what's going on here? I run similar currents thru the e3 mini vs the D3

[dc42]

@luke-slaboratory, do you definitely have microstepping interpolation enabled?

If there is insufficient VIN voltage to supply the requested current at high speeds, then the motors will become noisy because microstepping won't work.

[Luke'sLaboratory]

@dc42 Yes - microstepping interpolation is on - generating at 16x.

This noise is both idle and in motion, however. In motion it makes plenty of sense, this machine goes fast, but the idle noise is always what gets me compared to the machine with an SKR mini

[dc42]

If the idle noise is different with the same VIN voltage and motor type, there are a few possibilities:

• Current setting is different. Does whatever firmware you are using on the SKR board set the current correctly?
• Standstill current reduction factor is different. On Duet Mini you can change it using M917. It defaults to 75%. Perhaps the firmware on your other board has a lower default.
• Other relevant parameters are different, for example toff, tblank, hstart/hend/hdec.

[Luke'sLaboratory]

@dc42

Thanks for the reply

1. 99% sure it sets it correctly - Klipper. When I TMC_DUMP the values seem to line up where I've asked them to be (I could be interpreting the registers wrong - klipper doesn't translate them like marlin/rrf does into mAmps)

2. Samsies - I made them match between the D3 Mini and the SKR mini, and they're the same between RRF/Klipper on the D3 mini, 75%

3. This is the curious part to me - When I run my D3 Mini in RRF, the standby noise is different in character, as well as just a touch quieter. When I'm running Klipper, the standby is noisier and the operation is noisier. This is with the same current delivery specified - RRF does it in Peak, Klipper does it in RMS, so there's a sqrt2 between the two

Klipper uses the following config as their defaults:
#driver_IHOLDDELAY: 8
#driver_TPOWERDOWN: 20
#driver_TBL: 2
#driver_TOFF: 3
#driver_HEND: 0
#driver_HSTRT: 5
#driver_PWM_AUTOGRAD: True
#driver_PWM_AUTOSCALE: True
#driver_PWM_LIM: 12
#driver_PWM_REG: 8
#driver_PWM_FREQ: 1
#driver_PWM_GRAD: 14
#driver_PWM_OFS: 36
#driver_SGTHRS: 0

is there anything in RRF you've specifically changed to match the circuitry/tuning of the D3 mini?

[dc42]

@luke-slaboratory said in A few problems after setting up board... Includng stepper sounds:

No, except we added an output filter to reduce EMI.

RRF defaults to tblank= 0 which I presume corresponds to the TBL=2 that you've quoted for Klipper. The other spreadCycle parameters look the same to me.

[Luke'sLaboratory]

@dc42

Interesting - I'll make some changes and give it a test to see what happens

[nmsmith89]

@dc42

I'm using the stock CR-10 steppers at 800 mA; VIN is measured at 24.2 V; 1/16 microstepping interpolation on

Do you have a model number for the stepper motors?
