TMC2130 Debugging - bad driver?

#1

Hello, I am planning on building my own 3D printer and although I do have all the neccessary parts, I am missing the heart which is a working board with stepper drivers.

Now let’s get right into my problem. I was testing my board with TMC2130 drivers connected to a stepper motor, however the X axis motor (altough communicating) did not move a bit. First I was guessing it could be the board, but after switching the Z and X drivers, the problem shifted so that the Z axis did not move at all.

I managed to get TMC_DEBUG working and after M122 I get these results. Notice the PWM scale. This number is always 0 no matter where I move the X axis driver. When moved to Z, the Z axis PWM scale was showing 0.

The drivers are from China from BigTreeTech and I had to solder CFG and unsolder R5 to get them to SPI mode. Board is a RAMPS 1.6. I am currently losing my mind as if to ask for a new driver. I checked the pins and the soldering work but that seems to be in order.

	Y = 0x80:0C:00:00

P.S.: Here is a Google Drive album with photos of the bad driver: https://photos.app.goo.gl/Reyud38MPxjkWAuS9
P.S.2: Yeah I know they are soldered upside down, but I would rather have them like this instead of messing up their sloppy soldering.
Thank you for all suggestions !

I did bridge and desolder the connection that they ask.

Hi, so I think it’s same problem like FYSTEC, Bridge on the TMC board:

The bridge for your board seem to be in the upside…
