I have been switching over from Ramps to Smoothieboard for the past couple of weeks. Yesterday I printed for the first time with the new controller. (Yay).
Now I am trying to define the center of the print bed where I would like the printer to start printing. I can’t figure out what setting in the config file I need to change.
I though it was :
extruder.hotend.x_offset
extruder.hotend.y_offset
But when I changed the values the print location didn’t change. BTW this is for a reprap style printer.
Any ideas?

Figured out the Problem.
M206 X-9
M500
solved my issue
I had to set the centre of the bed as 0,0 to use delta grid compensation. My Axis travel on X & Y is 362mm. Therefore in the Config file i set the Alpha & Beta Min to -181 and the Max to 181, this gives the 0 in the centre of the bed. This change also needs to be implemented in the Slic3r.
Thanks

I marked the center of my bed with masking tape and an “X”. I then moved the nozzle directly over that point. Then I lowered the nozzle until it was a piece of paper above the bed. Then I typed M306 X0 Y0 Z0 and then M500.
Well if that works then that’s good. Me personally i prefer to use a bit more of a mathematical approach 
Then why waste my time answering. If you only want a specific type of help, say so up front and I won’t waste my time again!
Wind your neck in Craig Anderson, I wasn’t asking for any help, in fact if you read the posts properly you will see I answered this post with my own answer.
How do you make the change in Slic3r?
