1V is really high for a single stepper, make sure the z motor doesn’t get too hot, and that drv8825 will need a fan on it at that temp.
The problem here seems to be the 660. Did you mount the bottom bracket upside down like in the pictures? If not it might be slightly bending the z mount. Are you sure it isn’t hitting something it is very tight fit.
Put up a few pics, maybe I can spot something off. If it works without the tool nice and smooth the tool is causing something. that z motor is extremely strong at.42v. I originally used a 42oz/in stepper and even it would break the brackets if I moved it into the table on accident.
