Darwin Concept Improvements

If you spot any things which are particularly awkward, have any ideas on a more efficient approach, or see any wasted opportunity please list your comments here. These notes will be a very useful resource to design of the second release.

Author	Area	Note
Vik	Opto bracket	A bit more of a gap for the opto's legs wouldn't hurt
eD	Bracket holes	Dimension the utility holes (e.g. on carriage) to fit standard belt brackets
Andy Kirby	XYBase	Do away with base diagonal ties and use a base board, Perfect Square & Alignment every time. Also allows Circuit boards etc to be mounted to it. Provide a template similar to that provided for Bed details
eD	XY table	Head position off centre of the X axis means more dead space
Vik	Extruder board mount	It fouls V1.2 board edge connectors
eD	Z axis	Lots of dead space here, due to motor position. However, potential use for dead space: build material reel space.
Zach/eD	Bolts	Magic (single) bolt length would be cool
Andy Kirby	Z Studs	Make Skate bearing mounts for Z Axis Studs (Top and Bottom) all 4 corners to remove wobble, Move Z Stud Drive to Base Board and mount on slides with tensioning adjustment. This should also free up a bunch more build height.
Vik	Y Belt Drive	Move the Y belt gear furthest from the Y motor to the other side of the Y axis bearing. This probably means mounting the Y belt clamps on the X axis square jig, but avoids filing that long flat - the gear now just slips on the end.
Vik	Z Motor	Move the Z motor to the diametrically opposite corner and take it outside the build area. We gain another 60mm of build height.
eD/Vik	Bolts	Replace M3's with standard M5's?
eD	Motor couplings	Standardise? Y coupling most efficient
Vik	Z Belt	Use beaded belt instead of toothed belt - the sort of stuff used for window blinds and securing vicious attack biros in the bank's foyer. http://www.raymortool.com/Gen_Info.html
