TMC2208 Drivers... how do I set these up with Marlin 2.0 and Rpi4b on your latest firmware (April 25, I think)?

I did go to :8181, but is said the expected folder wasn't found. I've never messed with other 3D printer boards or Drivers before and thought this was much more plug-n-play than it's turning out to be. I have Version 2.0.

secondly, it appears facebook login is broken, as I had to create a second account with google to sign in.

Mark,

Picture 1 and picture 2 in your documentation disagree. One shows Jumpers configured for UART one way, and one shows them configured another. Please clarify these configurations. As another user on this forum noted, your documentation is very light.

@Yue Mark I appreciate the changes.. if I want to use UART, do I till need to solder the PDN pins on the drivers?

@Rick Carroll 😁 . There are 2 PDN pins, one is for UART and the other is unused, I don't think it needs soldering.

I had just asked this same question on the Facebook group; guess I know the answer now. No bridges need to be soldered; glad to hear it. My workbench is covered in HAM radio stuff.

it does not matter, you can tune the voltage on the steppers with the Pi connected. there are isolate resistances between the signal lines,and fuse unidirectional diode for the stepper power. But it also needs to be careful.

Secondary question... Should I be tuning the Voltages on the steppers with the PI connected, or separate from it, or does it not matter?

could you take a screenshot of that error? or maybe your img file of RPI4b is old before April ? https://mega.nz/#F!qJgHzRwB!Sl6hKYqNDLAtKXnzekdB3A

this is the same as when I did the pandapi20200405. no updates after install, just booting and trying to get it running.

Cloned git to Pi.... still no dice. Make succeeds, but running

☹️ after several hours.. i still can't get to the marlin code except through ssh (because I copied it from git), and now, when I turn it on, for some unknown reason I get thermal runaway shutdowns after 5-10 minutes. I though this was supposed to be a plug n play upgrade. Very disappointed. Over a month has gone by, and I am unable to print. Partially because life gets in the way, but when the documentation makes this look like no bigger a deal than a Big Tree Tech board, I feel like wtf... Furthermore, I have double checked the downloads... and, there is no marlin configuration.h on the image to configure from, *at all.*

I am not a programmer, but I can muddle through what I have to. I can run linux just fine, and used to be a certified Linux Admin. I feel like I shouldn't need to be some sort of engineer, so I can reverse engineer this and make it work. I'm installing it on an Ender3 which the maker says it's practically designed for, and he runs tests from. Do I have a bad board? Are all your downloads hosed? What gives?

Edit: also the LCD starts out OK and then after a while, keeps getting garbled. Yes, I'm still using the Creality LCD it came with.
