[BUG] Dual Z provides incorrect current/stealthchop modes

[CarlitoGrey]

Bug Description

Enabling Dual Z causes startup current to differ, and stealthchop to be disabled.

My Configurations

Marlin 2.0.x branch My code is here SKR 1.1 Pro TMC 2208's in UART Pins is set to default as of 2.0.1, although I did try adding:

define Z2_SERIAL_TX_PIN PD6

define Z2_SERIAL_RX_PIN PD6

define X_DRIVER_TYPE TMC2208

define Y_DRIVER_TYPE TMC2208

define Z_DRIVER_TYPE TMC2208

//#define X2_DRIVER_TYPE A4988 //#define Y2_DRIVER_TYPE A4988

define Z2_DRIVER_TYPE TMC2208

//#define Z3_DRIVER_TYPE A4988

define E0_DRIVER_TYPE TMC2208

define E1_DRIVER_TYPE TMC2208

//#define E2_DRIVER_TYPE A4988 //#define E3_DRIVER_TYPE A4988 //#define E4_DRIVER_TYPE A4988 //#define E5_DRIVER_TYPE A4988

if AXIS_IS_TMC(Z)

#define Z_CURRENT       800
#define Z_CURRENT_HOME  Z_CURRENT
#define Z_MICROSTEPS     16
#define Z_RSENSE          0.11
#define Z_CHAIN_POS      -1

endif

if AXIS_IS_TMC(Z2)

#define Z2_CURRENT      800
#define Z2_CURRENT_HOME Z2_CURRENT
#define Z2_MICROSTEPS    16
#define Z2_RSENSE         0.11
#define Z2_CHAIN_POS     -1

endif

Steps to Reproduce

define Z2_DRIVER_TYPE TMC2208

define Z_DUAL_STEPPER_DRIVERS

Expected behavior: [What you expect to happen]

Current and stealthchop settings should match for Z and Z2

Actual behavior: [What actually happens]

Current and stealthchop settings differ.

work fine for me on bugfix 2.0.x which is newer than 2.0.1

remember to do M502 and then M500 after you flash firmware, i made that mistake and my microstep did not match

[CarlitoGrey]

@boelle thank you, this was my mistake.
