Sorry for the double post.

After playing with Slic3r and Repg I found I can successfully use them together. The only issue is when I input the build dimensions of my printer 150mm X 145mm and set the center point at 75 X 72.5 two things happen:

When the extruders move to the front left to warm up it is hitting the side of machine creating a crunching noise. Then when it goes to print it prints off the build table on the back right side. So I then selected the center to be 0 X 0 and it then posts closer to the center but still makes the extruder hit the left side of the machine.

I will play with the dimensions more to see if I can get it to work better.

Also before it starts printing it releases a large amount of material and then begins to print the skirt. Anyway to modify the gcode with this?
