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

Re: Nema 17 Stepper Motor Noise
October 01, 2016 05:10AM
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.

I use Stepper Motor - 68 oz.in (400 steps/rev).

I heard half-stepping options. Motors work quieter with half-stepping. How to change full stepping to half stepping?
Re: Nema 17 Stepper Motor Noise

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

Thank you for your helping. I changed the pin and current values and sound decreases, but "viyuv viyuv" sounds continue to come.
Re: Nema 17 Stepper Motor Noise

The step pulses are too short. Try changing it to 5 us.

# Arm solution configuration : Cartesian robot. Translates mm positions into stepper positions
alpha_steps_per_mm                           161               # Steps per mm for alpha stepper 78.7402
beta_steps_per_mm                            161               # Steps per mm for beta stepper 78.7402
gamma_steps_per_mm                           640             # Steps per mm for gamma stepper 400


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.

Sorry to make you confused.MKS SBASE is compatible with Smoothieware that supports 1/16 and 1/32 .But MKS BASE is MEGA2560,use 4982stepper drivers which only supports 1/16.

Yes, my motor is 0.9 degree. Which values should be double?

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.
Re: Nema 17 Stepper Motor Noise
December 22, 2016 12:43AM
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.

Astrosyn dampers are awesome! I found them! Thank you smiling smiley 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.
