5160 not configuring as expected #1

Closed Cncninja closed 1 year ago

Cncninja commented 3 years ago

I have a SKR1.4 board with TMC 5160 in SPI. when i poll the drives this is what is see below. If I adjust the threshold it seams to change my steps per mm, Olso the Vsense is set to .075 in the config but the poll shows N/A the motor runs very choppy like is has no micro-stepping. I'm not sure what could be the issue. Im using IOsender 2.0.34, and the lpc176x_210809 build. ice_screenshot_20210912-121918

You see that change in the settings or in the speed or distance traveled - or both? Could it be due to the microstepping beeing set incorrectly?

the Vsense is set to .075 in the config but the poll shows N/A

AFAIKT the 5160 does not have a vsense setting so it is ignored and reported back as N/A (Not Available).

motor runs very choppy like is has no micro-stepping

Have you tried with a higher current setting? Is the motor loaded (in a machine?) or not?

I'll have to wire up a SKR 1.3 board to check this again - I'll see if I can find time tomorrow.

the settings do not change still shows the same steps per mm and 16 micro-steps, but the physical motion changes just like if I changed the steps per mm or micro stepping.

the motor is just loose not connected to anything, I have 5160 in X and 2209 in standalone mode in Y for comparison. The 2209 is unbelievably smooth, the 5160 acts as tho it has no micro-stepping very choppy the SPI polls just fine and i can make changes but they just don't seem to change what it's supposed to.

I have the bigtreetech 5160 V1.2 and all the Marlin videos and Bigtreetech pdf shows to set the 5160 Vsense as .075 So im not sure why.

Sorry the Rsense value not Vsense

I am currently stuck experiencing the same Issue on my Trinamic2209 equipped SKR1.4 Turbo - M122 I makes the board unresponsive and forces a hard reset, anything I could try?

@fairderben I have refactored the soft UART code and just committed the changes, hopefully it works now. I do not have a SKR 1.4 board to verify the code with, and there are many different TM2209 drivers out there requiring different links/wiring... I have tested with a SKR 1.3 board and Watterot drivers.
