btt 2240 v1 drivers giving error.

Unable to write tmc spi 'stepper_z' register DRV_CONF

How do i make these work?
RATOS config changed but still not working. ( dont understand why a config program doesn't config).
Lots of posts about 2240's but no fixes posted.
How did you get them to work?
Help appreciated. Thanks.

Solution

Have you tried moving drivers around to see if the error follows the driver? It might be defective
