Yes, there are 2 server commands to tell it to ignore moves for size computations
@nosize
Ignore next print moves for object size calculation. This is interesting if you make a extrusion at a fixed position. Then the server will include that into the size and that may lead teh rendere to show a much too small object.
@size
Stops the @nosize command from neglecting size computation. Never forget this if you use @nosize. They should always come as a pair.So start with;@nosizeand at end of start gcode put ;@size
