I AM TRYING OUT A FEW MODIFICATION ON THE MOTOR ARM.
MADE SEGMENTIZE MUCH BETTER.  YOU JUST INPUT A FEW MACHINE COORDINATES WHERE THE EXTRUDER IS TOUCHING AND THE PARAMETERS GET OPTIMIZED.
Updated the motor arm for gus to be easier to tighten a spool and easier to screw in the guitar tuners.
Added filament drive to gus bom
Update BOM.csv

Made the screws that hold the limit switch longer to get a more positive hold.
Merge remote-tracking branch 'upstream/master'
