Latest firmware 2.0.6 stepper motors much louder? #389

Just downloaded the latest firmware 2.0.6 for my SKR Mini E3 V2.0 board (posted a couple days ago) and the unit is much louder than the 2.0.x bugfix drivers and feature set seems a lot smaller in the menus. Thinking of going back. I have an Ender 3, no BLTouch or anything.

UPDATE: Went back to 2.0 Bugfix and nice and quiet again. Again went back to 2.0.6 and LOUD. Did they not load the drivers? Went back to 2.0.x Bugfix again and staying there for now. I thought I was crazy and even my wife (who knows nothing about this stuff) said definitely louder. It was like the original Creality board. I think they forgot the 2209 stepper drivers or something.

Came here to say this. It was the first thing I noticed as soon as I put the new firmware on.

Same issue here. Had to install previous version because of noise.

Same issue here. Installed latest 2.0.6 firmware and now the stepper motors making a grinding noise.

davidv3rs commented 4 years ago

@chiibis where do you get the previous version source?

davidv3rs commented 4 years ago

Found the fix:

Configuration_adv.h Uncomment lines 2407-2409

  /**
   * TMC2130, TMC2160, TMC2208, TMC2209, TMC5130 and TMC5160 only
   * Use Trinamic's ultra quiet stepping mode.
   * When disabled, Marlin will use spreadCycle stepping mode.
   */
  #define STEALTHCHOP_XY
  #define STEALTHCHOP_Z
  #define STEALTHCHOP_E

Looks like Stealth Chop was turned off. Make sure you run M502 and M500 after updating the firmware.

urshurak776 commented 4 years ago

Thanks David! Wonder why they changed it?

urshurak776 commented 4 years ago

What does M502 and M500 do?

What does M502 and M500 do?

Resets your EEPROM.

So, I downloaded the latest Marlin 2.0.6.1. Followed the guide on reddit For the SKR Mini E3 2.0 and watched video from Chris Riley (Chris’ basement in youtube.). Compiled it, exported the bin file and flashed it to the board. Everything worked great EXCEPT my computer would not recognize the board when plugged into my PC. Drivers were fine. Just to check, I flashed back to 2.0.X bug fix and my computer recognized it again. Checked the serial port is -1 and serial port 2 is 2. Not sure. Good news is the stepper drivers were nice and quiet again, but I need functionality with the computer.

I also tried overwriting the config.h and advanced.h files with the ones from BTT’s site but it wouldn’t compile. Not sure why. So, for now, sticking with the 2.0.x bugfix.

Hmm, I'll look into it.

urshurak776 commented 4 years ago

Think I figured it out. In the platformio.ini file I didn’t update:

default_envs = STM32F103RC_BTT_512K. I left it at default value.

I should have copied all three files over and made your changes on the advanced configuration file. I’ll try it in morning and report back.

Thanks David.
