Need some help getting TMC2130s to work with my BTT Octopus Pro. I’m running Dual-Z stepper motors in a corexy setup. I can confirm that my previous setup worked just fine in UART, TMC2209. But i needed more power to push my Bed up the shift which prompted me to look into these SMDs. I’m using TMC5150s in my X/Y config and it’s working just fine. However my Z returns this error when I try to move it.

Ive gon through a fair share of github issue pages related to a similar issue with other boards, some suggesting cutting pins and I’m trying to avoid that as much as possible.klippy.log (2.9 MB)klippy.log.config0019.cfg (14.0 KB)

In your printer.cfg I do not see any TMC2130 config blocks. All I can see are settings for 5160 and 2209
Ahh, uploaded the wrong file. I have updated it now.

The sense_resistor does not look quite right. Typically 2130s have 0.11 Ohmdriver_* settings are coming from where? I’d recommend to delete them if you are not sure that they really match your stepper and your application needs.
I’ve been trying different configurations found online but this is the current one below:

[tmc2130 stepper_z]
# uart_pin: PC6
cs_pin: PC6
spi_bus: spi1
run_current: .800

[stepper_z1]
step_pin: PG4
dir_pin: !PC1
enable_pin: !PA0
rotation_distance: 8

[tmc2130 stepper_z1]
# uart_pin: PC7
cs_pin: PC7
spi_bus: spi1
run_current: .800
sense_resistor: 0.110

The specific stepper is StepperOnline E Series Nema 17 Bipolar 0.9deg 30Ncm(42.48oz.in) 1.5A 42x42x38mm 4 Wires and can be found here
Whatever setup I’ve tried so far throws the same error.

The jumper settings of your board are set to SPI for the relevant steppers?
Yes.
Should anything be connected to the jumpers found here? If so I’m not quite sure how.

No
Nothing is connected there.

Sorry, no further ideas.
