Welcome to the SeeMeCNC Community

So here is my story...

I purchased a V2 as a kit around January last year and after a bit of a learning curve (thanks JJ) I was successful. Well, I received the V3 self-calibrating head for a Christmas gift this year and after installing it I’m having an issue. After running the G-code for the initial calibration the X & Z arms go up and the Y arm goes down. I will admit before I started the endeavor I had little knowledge, but I feel know I now a bit and cannot figure out why this is happening. Any help would be greatly appreciated!

Thanks so much,
Jason

Yes the old V2 kits need a different y direction than the current firmware has. Look at configuration.h file line 378 and change
from: #define INVERT_Y_DIR 0
to: #define INVERT_Y_DIR 1
At least that is where the change was for the december firmware I used.

Read thru the V2 forum looking for V2 hot end upgrade posts where this has been discussed.
