GTR V1.0 and BTT TMC2208 Error:ALL LOW #58

Open edouglas37 opened 3 years ago

edouglas37 commented 3 years ago

So i have a BTT GTR v1.0 and 6 BTT TMC 2208's V3.0 UART's

Now the problem is . 4 test with no errors 2 test with errors.

Firmware: Marlin Version: CONFIGURATION_H_VERSION 020008

17:05:37.978 : Testing X connection... OK 17:05:37.997 : Testing Y connection... Error: All LOW 17:05:38.006 : Testing Z connection... OK 17:05:38.025 : Testing E connection... Error: All LOW 17:05:38.034 : Testing E1 connection... OK 17:05:38.042 : Testing E2 connection... OK

I have tried Swapping the steppers but the X and E0 still have the same error so its not the steppers its either something on the board or something in the firmware.

I'm having the same issue with my BTT GTR 1.0 and BTT TMC 2208 V3 UART.

But my issue is only on the X axis.

I've also tried swapping drivers but no success.

Here's my TMC DEBUG Output:

@hiperlouro i changed boards, then swapped the drivers around and got x to read normal. I think it might be a stepper issue ?

Although i had tried that on the other board and it didnt seem to help so could be a combo issue as well

I've received the ALL LOW error message every time I boot my BTT GTR1.0 board that is running Marlin 2.0.7.2. But so far the board seems to function OK. It has TMC2208 stepper drivers installed. I've done everything I can think of to find or identify the cause of this error message, but have found neither a cause nor a solution. What I have found is that people have been seeing this error for at least a couple of years.

Today I used VSCode to search all of Marlin (and maybe PlatformIO too - I'm not sure how VSCode does it's searches) for the text "ALL LOW" and found nothing. So maybe the error is coming from somewhere else? I'm using a BTT TFT70 screen to communicate with the GTR 1.0, so maybe there is something going on with it - the TFT 70.
