Changed Vref to 1.1V
Changes was made on the Trimpot?
I discovered UART communication errors on multiple axii
Wich Axis?
have you tried to raise the current for e0?
Hi and thank you for your reply. Yes the change was made with the trimpot. I can't quite remember which axis had issues, I believe X, Z and E0. All all working correctly now except E0.
The video in the link below, starting from 0:55, mentions the vref should be between 0.8 and 1.1V for standard nema17 motors. It's getting hot - How to set the Vref on TMC2208 I remember the extruder vref was at 1.4V, and on this vref it shut down mid print. I have not tried raising the vref again. To what voltage would you recommend?
1.4Volt seems too high for me, but shouldn't have killed the driver already. 1.1V is ok (my bad I thought about tmc2209 @ answering)
Rebooting made extruder move again. Changed Vref to 1.1V on all BTT TMC2208 V3.0 stepper drivers and test-printed again, problem remained.
M122 shows Error: All LOW on E0 still after the reset? Or OK?
Non of your links are working so it's a bit difficult to find the sources ;-)
Checked if the UART cable set correctly? Tried to swap cable?
M122 keeps giving E0 ALL LOW also after rebooting and also after re-flashing firmware. I have one TMC2130 which I also tried, set up in SPI mode, which resulted in ALL HIGH. The SKR 1.4 Turbo should have internal circuitry to allow direct UART communication with the LPC1769 chip, so I have no UART cable. I did try plugging in a different stepper motor cable, the one from Z axis but had no effect. Could I route the UART signal from the stepper driver to a different pin on the board? Not sure if that might help but could be worth a try.
sorry for the broken links, I've updated my replies and fixed the links. I wasn't using the syntax right.
Sry, but routing pins from stepper driver is above my experience.
It looks like broken board. Can you replace it?

The board is almost brand new so I don't believe it's broken, however as I've seen so many people with the same or similar problems I feel it is due to how the board is designed. I don't have a replacement by hand, other than the original Melzi board but it is incredibly loud. I'm either considering to go to the original creality silent board I can buy from a local webshop or try out the mks Robin board.
I also have this problem, runs a little (Printing) And then it stops. I also uses skr 1.4 turbo and TMC2208 in uart mode.
I installed the BTT SKR 1.4 Turbo and have been able to print for a while. Recently the extruder would stop mid print. X, Y and Z would keep going and heating was kept on. After stopping print extruder wouldn't move with loading/unloading commands, above Cold Extrusion temperature. Rebooting made extruder move again. Changed Vref to 1.1V on all BTT TMC2208 V3.0 stepper drivers and test-printed again, problem remained. After running M122 with Pronterface I discovered UART communication errors on multiple axii. All communications on X, Y and Z are OK now, but I am unable to resolve E0. I also tried changing the pins of E0 to E1, but problem persists there too. I tried multiple stepper drivers, all pads soldered correctly but still ALL LOW on E0. Also tested with known working ones (from X, Y or Z).
I added the TMC stepper library below:
TMCStepper=https://github.com/teemuatlut/TMCStepper/archive/master.zip
Also tried modified library:
TMCStepper=https://github.com/sjasonsmith/TMCStepper/archive/stopListeningOnBegin.zip
Also tried adding SoftwareSerialM but to no avail:
SoftwareSerialM=https://github.com/FYSETC/SoftwareSerialM
My Configurations
Printer: Ender 5 Board: BTT SKR 1.4 Turbo with 3.5 TFT firmware: Marlin-bugfix-2.0.x , downloaded yesterday Stepper drivers: BTT TMC2208 V3.0
configuration.h and configuration_adv.h Configuration.zip
Full M122 output:
Steps to Reproduce
Expected behavior: [What you expect to happen] report: Testing X connection... OK Testing Y connection... OK Testing Z connection... OK Testing E connection... OK
Motor motion on E0 when above cold extrusion prevention, completed print
Actual behavior: [What actually happens] Testing X connection... OK Testing Y connection... OK Testing Z connection... OK Testing E connection... Error: All LOW motor motion above cold extrusion prevention, but stops mid print.
