I have Tevo Tarantula Prusa i3 printer with Marlin firmware.
The print that is centered in slicer is way off center on the bed (about 3-4cm in both X and Y). I have calibrated the firmware to 0 means 0 position. I mean that when X or Y axis home, hit the switch and stop, the offsets in the firmware make it exactly 0. So if I manually move axes via LCD screen the position reads exactly as it is on a building space. It travels on screen exactly to the printable dimensions of the bed. So I can move from 0 to 200mm on X for example. Any further and I'd hit the frame. The build size is set exactly to those values in slicer but the print starts completely off.
Not sure what to do and why is it happening? I have no start Gcode that plays with XY movement. Here are my Marlin values:
#define X_MAX_POS 202
#define X_MIN_POS 0
#define Y_MAX_POS 262
#define Y_MIN_POS 0
#define Z_MAX_POS 235
#define Z_MIN_POS 0
#define MANUAL_X_HOME_POS 0
#define MANUAL_Y_HOME_POS 1
#define MANUAL_Z_HOME_POS 0
