Re: No power to Z-axis in Marlin with TCM 2130 Drivers.

have you double checked all the jumpers from the stepsticks to the AUX2 and AUX3 connectors on the RAMPS?

Since your X/Y work and your Z does not I wonder if the lines from the Z stepstick are the problem...

P.S. The settings for TMC2130 SPI are in Configuration_adv.h
