Geeetech

I followed the instruction on the Wiki, compiled and uploaded the edited firmware to the mini G2s with no problem.

When I try to home the printer, Y is going up, Z and X is going down. As matter of fact, in any movement of any axis Y is going up, X and Z is going down.
The setting must be wrong somewhere, I have no control of the motor either in Repetier host or from the LCD.

Can someone email me a working well set firmware for the Mini G2s, or pointed me on how to fix this problem.

Many thanks.

Download it here .

Try changing these parameters in the firmware and re-upload the sketch:
#define INVERT_X_DIR true // for Mendel set to false, for Orca set to true
#define INVERT_Y_DIR true // for Mendel set to true, for Orca set to false
#define INVERT_Z_DIR true // for Mendel set to false, for Orca set to true

You might need to play around with the directions so they are all heading in the same direction (up) when homing.
