Describe your issue:
… only reading temps, STEPPER_BUZZ STEPPER=stepper_x → Unable to write tmc spi ‘stepper_x’ register GLOBALSCALER
at 48v or/and 24v same at usb-serial or usb-can conection,
no fans only temp. i tink is wrong pins ? has a way to identify the pins.
Please confirm that you have really pulled this change correctly. The process you needed to follow:
Pull in the changes of PR #6683 into your local Klipper
Build a new RP2040 firmware
Flash the firmware
Restart Klipper
On a unrelated sidenote:
You a running 0.8 A stepper motors off a board that is designed in hardware to run steppers up to 6 A.
This means the drivers will be severely limited in controlling the steppers current.
This is not related to the error you are having, but overall the rated current of the drivers should halfway match the rated current of the stepper motors.
As such, products like the PITB can be considered as unsuitable for use in “average” 3D printers.
Thank you, yes, very good notification, there are so many variables that we lose in the simplest ones. Note that in the first one I did not update the pitb, but in the second one everything is updated. It is under test, so there is no power to the motors, I think it is broken, there is no fan on the two pins gpio0 and gpio18, and the motors ffffff*f, only temperatures, other connections not tested, I have already tested on USB, USB CAN, on CAN with 3 different CAN boards, all without fan, only temp and endstops. What do you think? I really wanted this to work.
There seem to have been some further updates to this Pull Request. Not sure how relevant they might have been as I cannot compare them as they have been force pushed and squashed.
Please update the PITB again from the latest KoiosLabs and flash again.
