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. |
