SKR Mini E3 USB Connection #2

ilakuli · 2019-07-08T06:57:51Z

Hello,

My SKR Mini E3 keeps disconnecting from any USB Device after about 15 seconds. Tested on Windows PC and Octoprint. In Windows, the board shows up and connects normally but after 15 seconds it just disconnects. In Octoprint the same thing happens. Firmware was configured and compiled according to the List provided on Github. Have noticed the issue with conflicting serial port information and tried both ways. Nothing solved the issue. Any help would be appreciated.

Thanks.

vyruz1986 · 2019-07-08T19:52:40Z

I can confirm the same behavior on my E3 Mini board with the latest build from Marlin directly (at commit 2b1c2a0)

Msq001 · 2019-07-09T01:15:18Z

I will test it

Msq001 · 2019-07-09T02:17:43Z

Can you provide firmware. bin file? I tested the latest version of marlin, no such behavior, and I uploaded a workable firmware. bin in here, you can try to use this to see if it works properly.

ilakuli · 2019-07-09T04:21:18Z

Firmware.zip
attached is the firmware.bin.

I will test your firmware but I cannot use it permanenlty since my Ender 3 hast a different hotend and auto bed leveling.

Thanks,

ilakuli · 2019-07-09T04:33:49Z

Your firmware resolved the issue. Can you provide the source code so I can add auto bed level and compile myself?

Msq001 · 2019-07-09T04:39:05Z

this firmware.bin is compiled from old version Marlin, and the source code have be replaced by new verison, this issue maybe the Marlin's bug, I will locate and fix it as soon as possible, when I fix this, I will tell you and upload the workable source code in here.

vyruz1986 · 2019-07-09T05:43:39Z

Could everyone please state which commit of marlin they are building and testing? I have this issue with commit 2b1c2a0 Will try later today with the bin file provided by Msq001, thanks

Here's a zip (with firmware.bin , github doesn't allow *.bin uploads) which demonstrates the problem.
firmware.zip

It was compiled by setting #define SERIAL_PORT_2 -1 and with marlin at commit ab99a80

Msq001 · 2019-07-10T02:42:25Z

hi~ I have upload source code, LCD12864 is ok, usb connect to printrun is ok

Msq001 · 2019-07-10T02:45:24Z

It's just download form Latest version MarlinFirmware/Marlin@a23021b

vyruz1986 · 2019-07-10T06:34:22Z

Below are 2 pictures comparing configuration.h and configuration_adv.h between the source code in this repository(https://github.com/bigtreetech/BIGTREETECH-SKR-mini-E3-/tree/2a167ef96c9170c63288a3c1d69b6dea9d913506/firmware/Marlin-2.0.x-SKR-Mini-E3), and MarlinFirmware/Marlin@a23021b , as you can see there are way more changes than what you currently have described in the instructions on how to flash Marlin. Likely if we apply all these changes to the latest Marlin sources, it will work as well. I'll give that a try tonight and report back here.
Configuration_adv.h

Configuration.h

vyruz1986 · 2019-07-10T20:41:41Z

Ok so after testing, I've done the following and have a completely working Ender 3 with the BBT SKR E3 Mini board.

Clone the latest version of Marlin (I used MarlinFirmware/Marlin@4e479ca)
In the repo you just cloned, copy the contents of config\examples\Creality\Ender-3\ to Marlin
In platformio.ini, change the following line under the [platformio] section:
env_default = BIGTREE_SKR_MINI
Make the changes described below to Configuration.h and Configuration_adv.h

Configuration.h

#define STRING_CONFIG_H_AUTHOR "(none, default config)" // Who made the changes.
#define SERIAL_PORT 2
#define SERIAL_PORT_2 -1
  #define MOTHERBOARD BOARD_BIGTREE_SKR_MINI_E3
#define X_DRIVER_TYPE  TMC2209
#define Y_DRIVER_TYPE  TMC2209
#define Z_DRIVER_TYPE  TMC2209
#define E0_DRIVER_TYPE TMC2209

Configuration_adv.h

  #define  Y_SLAVE_ADDRESS 1
  #define  Z_SLAVE_ADDRESS 2
  #define E0_SLAVE_ADDRESS 3

This works for my printer.

vyruz1986 · 2019-07-10T21:03:26Z

Apparently I cheered too early :) The control knob still isn't working. Printing over USB works fine, but pressing the control button causes the board to freeze up :(

Edit: Also the USB connection is still dropping after ~15 seconds, so this specific issue isn't really fixed it seems.

this issue please comment out #define SPEAKER in configuration.h file

Msq001 · 2019-07-11T01:12:19Z

and I wil update your feedback in readme.md, thanks for your feedback !

vyruz1986 · 2019-07-12T08:11:27Z

Control knob issue was fixed by commenting out #define SPEAKER as suggested by @Msq001 , thanks!

Xenon-2510 · 2019-07-14T05:51:14Z

Any update on this issue? I have got the board up and running but have an issue with the X axis stepper driver and cannot debug as the serial connection doesn't work.

Have you installed Maple USB port driver on your computer? Can you debug with this firmware. bin

Xenon-2510 · 2019-07-18T05:55:54Z

I will check this firmware out later today, I have installed the Maple driver on my pc but I am also trying to use Rpi3 with Octoprint. I will feedback the outcome.

Xenon-2510 · 2019-07-18T19:05:53Z

Hi,

So i tried the firmware you suggested and unfortunately it did not work, I then tried a firmware that I was sent through facebook earlier this week by Zyfio (see attached) this worked fine with the serial connection both from my PC using pronterface and my Rpi3 using Octoprint. So i know that the board works and that it is a firmware issue, I have attached the working firmware for you to try but I am afraid I do not have the source.

I am hoping that this is of some use, please let me know if there is anything else that I can do to support.

firmware_working_serial.zip

Msq001 · 2019-07-19T05:43:39Z

Hi， Even if you updated the firmware. bin that we have compiled here, the serial port is still unrecognizable?

Msq001 · 2019-07-19T08:49:14Z

SO SORRY for this issue, USB Serial can't recognize or unstable because of: USB slave needs to connect a pull-up resistor to VCC in D + to tell USB host it's own device type, we use a P-MOS to control whether the 1.5k resistance is pulled up or not, and the GPIO of P-MOS should "output" a stable low level, but It was "input" state before, so the USB device could not recognize or be unstable.
I have updated the firmware.bin and source code now, It should workable now

nicstoun · 2019-07-19T13:41:15Z

Hi, i think soon buy this board ..i track this issues ,still board don't have stable firmware for everyday use ?

Regards

Msq001 · 2019-07-19T13:48:54Z

the SD card print, and usb serial is ok now in my tested, but I need more feedback, this source code and firmware.bin should workable and I have Creat a PR to fix this issue in Marlin master branch MarlinFirmware/Marlin#14679

Ok, for that i see only usb have some issues now , if flash firmware provided later i get board all be fine right ?

Xenon-2510 · 2019-07-19T13:55:38Z

I have tried the source firmware this afternoon, seem to be getting inconsistent E1 Thermal runaway issues on boot. Do you need to add in a grace period for this board?

Msq001 · 2019-07-19T14:01:45Z

@Xenon-2510 This seems to happen only when you connect to USB CDC serial at startup, right? If wait 4-5s for motherboard to startup completed, then connecting USB CDC Serial is normal ?

yes, It should be fine.

Xenon-2510 · 2019-07-19T16:20:27Z

@Msq001 - yes, it seems to only do it when the printer is turned on with the USB plugged in. Is there anyway this can be rectified as this didn't happen with the stock board? I like to leave Octoprint connected so I can remotely turn the print on and start a print from the Web interface.

vyruz1986 · 2019-07-19T23:03:01Z

I tried building the latest bigtreetech/Marlin repository, and can confirm the USB issue is fixed 👍
Thanks BTT!

thomasgerman · 2019-08-12T19:03:06Z

why can not I connect the board to usb? I loaded the last marlin, when I connect the cable hangs up the board and the hotend fan whistles. where is the problem?

mejtoogood · 2019-08-17T13:04:31Z

Board still gives thermal runaway error when USB connected at boot. Not prepared to use workaround which degrades safety. Fix was in pipeline 24 days ago, what is status?

bigtreetech · 2019-08-22T07:15:09Z

Silversurfer79 · 2019-11-29T00:30:44Z

Maybe a silly question, is there a bin file that i can load from SD or do i need have the SKR connect via USB to Adr or a PC to do this?

Hi, I connect the USB to a pc/octoprint it works but when i sent M305 for PID autotune my connection will always close and won't open again. Does anybody know what to do? Thanks, Adam.

ajahongir · 2023-03-01T15:14:48Z

having problems with board. once as i flash with new firmware. i connect by usb and send M501 M500 to clear eeporm and save settins. make another minor changes and flash again but next time usb connection not working. its hang up when it try to connect by pronterface, all configurations are same. only i change offsets. i can not figure out why it stops to connect. tryed to reinstall firmware and so on. dont help is there any ideas? but when you connect. it recognize on PC.
