SKR 1.4 turbo won't connect to octoprint

[Fisisist]

I upgraded my Artillery Sidewinder X1 board to a BTT skr 1.4 turbo and can't connect to my octoprint.  It was working fine on the old 8 bit board.  Has anyone had any problems connecting or any luck fixing the issue?  Thanks,

Hi, you use Marlin firmware, can the motherboard update the firmware and connect to the computer normally? If so, the motherboard is fine. This might set up problems.

Hello, I'm having the same issue. 
I'm using the Marlin Firmware from here - https://github.com/bigtreetech/SKR-2

This is the board I purchased - https://smile.amazon.com/BIGTREETECH-Motherboard-Printer-Upgrade-Compitable/dp/B0943WVM5B

I did try to connect to my windows based machine, the device is showing up but its not registering properly cause of a missing driver. I believe this is the driver I need to install - https://github.com/bigtreetech/SKR-2/tree/master/Firmware/Marlin-bugfix-2.0.9.2.x/Marlin/src/HAL/STM32F1/maple_win_usb_driver

But I really really really don't want to because the driver is unsigned and would require me to turn off security features on my machine to install. Nevertheless I do see the board on windows, I see two red power LEDs and a green LED on the board light up. The BL Touch is responding to boot up, and all the fans on the printer are turning on as expected. 

When I updated the firmware, the board renamed the firmware as expected after the upgrade. 

Only problem is I don't have a LCD panel for this board, and would rather control it over USB using octoprint. 

This is what I see in octoprint's serial log

I've attached my marlin configuration.h

Hi, this shows that the motherboard can update the firmware normally. You can try to update it with the test firmware I sent you to check if it can connect to the computer properly and recognize it.

firmware.bin

[gouthamravee]

Tried the new firmware, seems to have made issues worse. The green light by the PSU isn't lighting up all the way anymore. Its staying sorta half lit. 

I'm not seeing the printer over USB on either linux or windows. 

 

 

Sorry about the photo quality, I tried to get the whole board in the photo. 

[gouthamravee]

Sorry about the multi-post. 

I reverted to my firmware to make sure everything was okay. That firmware cases the green light to turn on, and the USB device shows up under windows and linux. But I'm not able to connect to the printer using either Cura or Pronterface on windows, this is more than likely due to drivers. 

 

I've attached my marlin configuration file here. 

Configuration.h

So I ended up buying this LCD screen - https://www.amazon.com/gp/product/B07VWF4W3J

Everything boots up as expected, but shows 'no printer connected' 

[gouthamravee]

I figured it out! 

I'm using this on a Geetech A20, which has a custom head cable, I got the wiring wrong with the temperature sensors. I guess that was preventing the board from starting properly. Anyways now I have a screen and USB controller with octoprint working. 

[BTT Tony]

OK. That's good. Before connecting the power supply, you need to check whether the wiring of the motherboard is correct, because the wrong wiring will cause damage to the motherboard.

Lmao no kidding! 
I wired the hot bed in backwards, I'm amazed I didn't cause a fire.
