Describe your issue:

“Unable to write tmc spi ‘stepper_x’ register GLOBALSCALER”

My Config
Printer board: MKS Robin Nano V3.1, Stepper drivers TMC5160, Motors LDO-42STH48-2804AC-R

Worked fine with TMC2209 in UART mode
Changed from TMC2209 on X and Y stepper drivers to TMC5160

When I had no problems:

[tmc2209 stepper_x] # uart
uart_pin: PD5
run_current: 1.4
hold_current: 0.5
stealthchop_threshold: 999999
interpolate: True

And now:

[tmc5160 stepper_x]
cs_pin: PD5
sense_resistor = 0.075
run_current: 1.0
spi_software_sclk_pin: PD0
spi_software_mosi_pin: PD14
spi_software_miso_pin: PD1
interpolate: false

Mailed Makerbase a week ago, no answer!
What am I missing?
Please help, I can´t be the only one with Robin Nano v3.1 nd TMC5160!

Hello @Matz !

Have you set the jumpers accordingly to the silkscreen at the back of the PCB?

BTW: Setting hold_current is not recommended. Besides, it’s way too low regarding to the run_current.

Copy/paste the title of your post to google. The 3rd hit is

TMC5160

MKS said set the Jumpers (As noted above)
OP replied “no joy”
One user posted they has success with modifying the pins on the driver board.
MKS replied only that they don’t offer a TMC5160 driver

Hello EddyMI3D

Yes I have connected, checked and rechecked pins under TMC slotts.

Hello cardoc

I did the bending of the third pin and it works.

A million thanks for pointing me in that direction.

Very satisfying to print at 250mm/s with the SP5!
