Homing problem

Post by remilton » Fri Aug 07, 2020 5:09 am

I have a strange problem. I just installed a new board in my A20M and also installed TMC2208 V1.2 Stepper Drivers. I also flashed marlin 1.1.8 with bltouch and inverted the stepper direction.

#define INVERT_X_DIR false
#define INVERT_Y_DIR false//false
#define INVERT_Z_DIR true//true

// Enable this option for Toshiba stepper drivers
//#define CONFIG_STEPPERS_TOSHIBA

// @section extruder

// For direct drive extruder v9 set to true, for geared extruder set to false.
#define INVERT_E0_DIR true
#define INVERT_E1_DIR true

The problem is that when I Auto Home, the x and y axis go to home then reverse and go to the other end and chatter.
I have flashed two different copies of the firmware with the same result.

Does anybody have an idea what is happening?

Edit: I found the problem. The new MB was missing the jumpers under the drivers. Carried jumpers over from old board, problem sorted.
