@sozkan what external boards are you using? do you have a link?

It seems right this time but with this "P5, P6, P7, P8" values all motors running with noisy signals and slower with vibration. Homing not successful at first. Distancing not correct.

looking at the datasheet I think your timing are not correct for the driver.
there needs to be at least a 6us setup time for direction
I would maybe try a timing of T3:3:6:0 -
Looking at the data fore the driver that you linked to, the other thing you may need to do is use the alternate connection method to the expansion board:
- Connect PUL+ and DIR+ driver input to the +5V pin on one of the servo headers on the breakout board
- Connect PUL- to STEP- on the breakout board, and DIR- to DIR-.
The data says that you can leave ENA+ and ENA- not connected. This is probably best until you get everything working, however the Duet won't be able to turn the motors off. Therefore, when movement is working correctly, you may wish to connect ENA+ to +5V on the breakout board, and ENA- to ENA-. Use whichever of R0 and R1 works in the M569 commands.

Hi,
It finally succeeds, running smooth and correct in calibration, homing perfect, by changing ;- Connect PUL+ and DIR+ driver input to the +5V pin on one of the servo headers on the breakout board
- Keep Remain PUL- to STEP- on the breakout board, and DIR- to DIR-.
- Revert back the P values to "P0, P1, P2, P3" ( Because Correct one Create noise like ball bearings broken and move uncalibrated ). Therefore I cannot control the default direction (S values) ( But however on the drive I managed to change it ).
In a conclusion, even if it is solved, working better with an incorrect parameter. However, a +5V connections make a good job.
I still want to work with the correct parameters as you advise.
Thank you very much.

Your external axes will be using default timing. Send
M569 P5and see what it says. It did not run well because of the T parameter settings you used:M569 P5 S1 R1 T3:3:5:0From the product page you linked, there's this, which shows the timing you should be using:
M569 T parameter, where Taa:bb:cc:dd:
aa = Minimum driver step pulse width, in microseconds = t3 in image = not less than 2.5us
bb=step pulse interval, in microseconds = t4 in image = not less than 2.5us
cc=direction setup time, in microseconds = t1/t2/t5 in image = at least 6us
dd=direction hold time, in microseconds = t1/t2/t5 = at least 6us
Enable signal t1 = assume that you have ENA+ an ENA- floating, so constantly enabled. Also, I think t3 and t4 are the wrong way around in the image, but they are the same value.From this, try:
M569 P5 S1 R1 T2.5:2.5:6:6 ; Extruder drive 0 goes Forward M569 P6 S1 R1 T2.5:2.5:6:6 ; X:A drive 1 goes Forward M569 P7 S1 R1 T2.5:2.5:6:6 ; Y:B drive 2 goes Forward M569 P8 S1 R1 T2.5:2.5:6:6 ; Z:C physical drive 3 goes ForwardIan

Hello. Thank you for your concern and effort.
I was busy with upgrading mechanical hardware.
I just came to this point once again. The problem is not solved yet. When P values changed to 5,6,7 sounds horrible and inccorrect. But when P values 1,2,3 it is working but not correct right?
Please see the video I make on youtube : Link for video. -
In your video it looks like you're getting an error message when trying to save the config.g and reboot the board. Failed to download config.g.
Are the updates you are making to config.g actually getting saved?
Can you please provide the results of M122 and M98 P"config.g" ?

Also, in your video it looks like you have the DWC web files in your /system folder. They should not be there. (The CSS, FONTS, JS folders for example, and the html.gz files, etc.) Those files all belong in the /www folder on the SD card.
I think there may have been a few mistakes made during a firmware update.

@Phaedrux it could be. Thank you for your attention. I am still on the learning curve.
-
You can see an example of the correct file structure here.
https://duet3d.dozuki.com/Wiki/SD_Card#Section_Creating_the_file_structure
Note that your /sys folder will also contain some .bin files for the firmware in addition to the listed .g config files.
It may be easiest to put the SD card into a PC to edit the file structure.

I realize now, you want me to send a command to the machine right? I can do it by tomorrow.
-
Yes, M122 will give us some diagnostic information including verifying what firmware version is installed. And M98 P"config.g" will execute the config.g file as a macro and echo back any error messages which are otherwise missed during power on. This would help eliminate any other syntax errors in config.g.
-
This may not resolve your noisy motors, but it will at least ensure we're working with a correctly functioning setup.
-
M569 P1 P2 P3 are fine if those cause the motors to move those are the correct ones. It's just targeting those driver numbers.
-
@Phaedrux
I will definitely do and share the result by tomorrow.But I am sure there is no imperfection on hardware and wiring. Because motors are accurately working on illegal code, but creating horrible sound and incorrectly working on legal code. That's means I have done something working during the firmware upgrade?
Because it is the latest stable update recently I messed up.
-
And yes, reduce acceleration and jerk. That should help a bit.
The motors are going to be loud. They are large and mounted to metal, but hopefully the adjusted timing and acceleration will make it a bit more bearable.

It's not illegal code if it works.

It`s some how stable on motor step control, but with those settings, I cannot control Enable or disable the motor features as well as the direction due to the illegal numbering. Because event Mr. admin "dc42" suggests for the external motor drives the stepper breakout board legal codes P5,6,7,8. Somehow these legal settings only working enable and direction settings and unstable step signals for the motor.
