---+ 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* | | eD | XY table | Head position off centre of the X axis means more dead space | | eD | Z axis | Lots of dead space here, due to motor position. However, potential use for dead space: build material reel space. | | eD | Bracket holes | Dimension the utility holes (e.g. on carriage) to fit standard belt brackets | | eD/Vik | Bolts | Replace M3's with standard M5's? | | eD | Motor couplings | Standardise? Y coupling most efficient | | Zach/eD | Bolts | Magic (single) bolt length would be cool | | Vik | Extruder board mount | It fouls V1.2 board edge connectors | | Vik | Opto bracket | A bit more of a gap for the opto's legs wouldn't hurt | | 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. | | 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 | | 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 | | 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. | -- Main.EdSells - 05 May 2007
