Hi,
When my stepper motors don't move, there are noise and sound that attached file below. I use MKS Base 1.3 and config file is below

I can't make out much from your recording, but kudos for trying it!
Is this something that was working and then failed, or are you trying to get it working for the first time?
When steppers don't turn there are usually just a few things to check.
1) motor current is much too high or low. If the motor is getting hot quickly, the current is probably too high. You values in the config look reasonable assuming typical NEMA-17 sized motors.
2) one motor coil is disconnected or wired backwards.
3) acceleration and/or speed is too high- your values look OK- check the speeds set in the slicer...
4) the motor driver is damaged- often occurs when the motor is connected/disconnected while the board is powered up. If one of the motor wires has an intermittent connection, it can destroy the motor driver.
5) there may be a mechanical problem (binding int he mechanism) preventing the motor from turning.

since your showing smoothie configuration I presume you talking about MKS Sbase 32-bit Controller not as you listed MKS Base
As I understand it this board is always in 1/16 or 1/32 microstepping mode

The step pulses are too short. Try changing it to 5 us.
Why does the definition on the left not match your note on the right? ~80 steps/mm is typical of a 200 step/rev motor with a 20 tooth pulley running at 16:1 ustepping.

I think the problem may be that the MKS SBASE uses DRV8825 drivers, which are known to be noisy with low-inductance motors when configured in fast decay mode, especially when using higher supply voltages. But I don't know whether the MKS SBASE does configure the drivers in fast decay mode. See [cabristor.blogspot.co.uk] for more.

I looked at the website (http://cabristor.blogspot.co.uk/2015/02/drv8825-missing-steps.html), but there is also sound (like a music) when extruder print a circle shape. I listen to Zortrax, Makerbot and Ultimaker, there is no sound when printing. Why? What are their boards, motors or motor drive?

That sound is entirely normal unless you either use stepper drivers with very high microstepping (e.g. 256x which is what I use), or you use dampers and soundproofing which I expect the commercial machines have.

That sound (like a music) is not normal. In commercial machines there is no music, it is very silent. Which value do you say for microstepping in config file (I shared it in the first entry). If you can help me, I will very happy.

Read all of my response, not just the first 4 words.
One of my printers uses 16x microstepping, no dampers, and has no enclosure. It produces the "music", which is normal for this design of printer. The other is virtually silent while printing, apart from the fans, since I switched it to 256x microstepping. Again it has no dampers or enclosure.
Your DRV8825 drivers are limited to x32 microstepping, which is better than the x16 that is still used by a lot of 3D printers. If you want to make it quieter without changing the drivers, you could try installing Astrosyn dampers if your printer has room for them. I've never used them, so this isn't a recommendation.

One of my printers uses 16x microstepping, no dampers, and has no enclosure. It produces the "music", which is normal for this design of printer. The other is virtually silent while printing, apart from the fans, since I switched it to 256x microstepping. Again it has no dampers or enclosure.
Your DRV8825 drivers are limited to x32 microstepping, which is better than the x16 that is still used by a lot of 3D printers. If you want to make it quieter without changing the drivers, you could try installing Astrosyn dampers if your printer has room for them. I've never used them, so this isn't a recommendation.

Read all of my response, not just the first 4 words.

Astrosyn dampers are awesome! I found them! Thank you
Additionally, which boards include 256x microstepping stepper drives? I buy it directly.

I think the problem may be that the MKS SBASE uses DRV8825 drivers, which are known to be noisy with low-inductance motors when configured in fast decay mode, especially when using higher supply voltages. But I don't know whether the MKS SBASE does configure the drivers in fast decay mode. See [cabristor.blogspot.co.uk] for more.
