You can connect or disconnect the USB cable to make the current adjustments, so long as you still have Supply Power.


They may require less current, you may be over driving the steppers.
Start with .4 test steppers then go to .5 test steppers , .6 test steppers ect... after they start working then you can fine tune the current.
Would not go above 1.6 for Z-Axis should start around 1.2-1.4
Would not go above 1.0 all others should start around .7-.8

When I received my 3DP11 the Extruder Stepper was wired incorrectly, running backwards.
("Took Forever to troubleshoot as filament kept leaking out, and thought it worked")
Had to reverse the wire pairs to make it run in the correct direction.

You can trace the wiring of the cable that the Z-Steppers works with, see if the wires go to the same pins of the Z motor wiring harness cable.
If you believe the Cable is incorrectly wired contact me will discuss how you may proceed from here.
