hello all I’m trying to use 3 z lead for gtr v1.0 I’m getting this error.
Unable to write tmc spi ‘stepper_z1’ register GLOBALSCALER
[stepper_z1]
step_pin: PD6
dir_pin: PD5

Hy,
Does it Work with stealthchop active?
Whats your supply voltage? The tmc 5160 seems to be really sensitive on its initial settings…
Have the 3 steppers own drivers or are they parallel or in row on one driver?
Hi @Motlow,
Please don’t guess on possible causes of an issue. It increases confusion and leads to lost time troubleshooting. If you know the root cause of an issue, feel free to post - if you don’t know, it’s fine to leave the post unanswered until someone does know.
Cheers,

A Unable to write tmc spi ‘stepper_z1’ register error is typically the result of incorrect wiring, incorrect configuration, or lack of motor power - see: https://www.klipper3d.org/TMC_Drivers.html#i-keep-getting-unable-to-write-tmc-spi-stepper_x-register–errors

Hello I found the problem. I did not have the steppers plugged in. I was just seeing if the config information was right. Once I plugged the steppers into their respective area everything works as it should. Sorry for the waste of time. Thank y’all for helping.
