Max height problem with printer

[adam120674]

it is at the bottom. When home is hit , the build table pulls all the way back and the extruder almost touches the left front corner of the plate. The z switch is made when this happens. I have 2 3/4" from the plate to the tip of the extruder max up. Control panel shows z:255.00 at this point and z:0.00 at the home and bottom position. Conversion chart shows 255mm is 10.03 inches.

ok I got it.got a new config file from manufacturer. Works correctly, after I loaded . But, every time a turn off machine it reverts back to before. I have to reload config file every time. This doesn't seem right to me. Any suggestions
