On Anet A6 I installed BLtouchwith original ANET3D v1.5,
Marlin-2.0.x and “Auto Home” and “Level Bed” work great.
Unable to get “Auto Home” and “Level Bed” to work on SKR-PRO-V1.2.
X, Y, Z axis move in the right direction but displacement is not correct.
X 10mm moves 5mm.
Y and Z 10mm moves 1mm
But with each “Auto Home” command, the Z axis moves up about 2mm instead of down.
Ditto for the commands “Motion->Home X”, “Home Y”. which are correct.
But “Motion->Home Z” increases each time by about 2mm and with each new command increases again.
Command “Configuration-> Probe Z Offset”, (given negative), has no effect. Z Axis does not drop below zero.
“Level Bed” doesn’t work either.
Stepper driver TMC2208 Uart
Some Configuration.h commands:
#define MOTHERBOARD BOARD_BTT_SKR_PRO_V1_2
#define SERIAL_PORT -1
#define BAUDRATE 11520
#define X_DRIVER_TYPE TMC2208
#define Y_DRIVER_TYPE TMC2208
#define Z_DRIVER_TYPE TMC2208
#define X_MIN_ENDSTOP_INVERTING true
#define Y_MIN_ENDSTOP_INVERTING true
#define Z_MIN_PROBE_ENDSTOP_INVERTING false
#define MULTIPLE_PROBING 2
#define INVERT_X_DIR true
#define INVERT_Y_DIR true
#define INVERT_Z_DIR false
I tried to change so many things with no positive result.
What is wrong please ?
So impossible to use the SKR-PRO-V1.2 card to my great regret.
And I wanted to install and use 3 RGB colors in an extruder and 3 stepper motors.
Thank you, gg
