[BUG ?] TMC5160 not working since update to TMCStepper 0.3.4

[Patag]

Hi all, Thanks in advance for your great (and probably hard) work. Here is my issue

Configuration

Printer still under assembling SKR v1.3 TMC5160 using SPI on X/Y/E (sensorless homing activated on X/Y) TMC2130 using SPI on Z1/Z2 (dual Z) Marlin bugfix 2.0 from May, 19

Description

Since TMCStepper lib upgrade to 0.3.4, X axis moves became weird (especially homing), impossible sometimes. LCD values related to TMC stepper not valid regarding default settings in conf*.h (Y and E nor wired, so not tested yet). M502/M500 doesn't change anything. Revert to TMCStepper lib 0.3.2 and all run fine.

Additional Information

Same configuration.h and configuration_adv.h, only TMCStepper lib changed between M122

Unfortunately I have to admit that I don't have further ideas right at this time. The current calculation seems to be spot on and the configuration seems alright.

@teemuatlut This is what it is doing in practice unless current settings are a lot higher than other drivers. Note: the same printer setup works great with other TMC drivers and was running TMC2208 via UART on the same control board before changing out for the TMC5160s. https://www.youtube.com/watch?v=mbs_DO4Mh4w

I don't know if its just my specific combination of hardware but stealthchop absolutely will not work correctly for my machine. just tried latest build out with same results as before. it is really bad with my two Z steppers in parallel

Is it doing like in my video above when trying to run Stealthchop?

[Black6spdZ]

@eightheads: yep almost exactly and I just figured it out.. stealthchop is a no go @12v especially with paralleled Z motors. I connected my adjustable lab supply up and ran the bed up and down while increasing the voltage. at 24v it sill had a little drone but at 26v was practically silent, like a tmc driver should be. the single X and Y motors were silent at about 18v though. well damn, guess I'll be switching out hot-end and fans and pray my bed can be rewired for 24v :(

I am testing these on a 12v printer currently... However, all other TMC drivers run great at 12v in stealthchop

[Black6spdZ]

I thought the same because i have some 2130s on another printer running 12v fine, smaller 1.8d motors though

[Black6spdZ]

got in my new nice fanless 24v 15a psu, bumped it up a little to 26v and it runs smooth and silent now

Even this issue is closed, I had the same kind of issue. I used TMC5160 V1.0 from BIQU. That version does have pin 6 floating, whereas it should be wired to the ground of the stepstick. Also the pin towards the SKR 1.3 board shall be cut. as pins 5 and 6 are shorted in mainboard. When I fixed that - i had no issue with marlin 2.0.x (I used experimetal SQUARE wave steppin optin, and the minimum step was default) now I have X and Y running TMC5160 and Z and E0 with TMC2130.
