Change default filament load location

[Sean Reitmeyer]

I'm new to Mbot and makerbot software, but have been using CNC equipment regularly for 7 years.

When I changed the default values in replicatorsingle.json to my specific build plate, all worked well in makerbot software with a couple of exceptions which I can't explain.

The default was 200mm by 200 mm, I changed to 160 x 160 and the center of the makerbot software is not the center of my buildplate, but my build plate is centered in the machine.

The biggest problem I have right now is the default location for changing filament during a print puts the extruder in a location that "misses steps" such that when I go back to resume, I'm about 20 mm off from where I should be in the x axis.

I would like to know what file to edit so I can set a predefined change filament location, at this point I'd be happy to just postive z 30 MM or something.

Thanks in advance, I'm sure I'll be able to contribute more than I ask once I get all the basics settled.
