X-axis from Igus
- Place order at end of this semester
- r start of next semester
- Purchasing Procedures
○ Should team follow standard MSD purchasing procedure?

X-axis - Visual of Scanning Length

Y-axis - Feasibility Test
- The y-axis from the P14551 Senior Design project
- Wanted to ensure that the axes could
○ Handle the weight they are expected support ○ Operate with the required accuracy
- Y-axis passed Feasibility Test and we utilize it in our system
- However the motion bed has some play in it and the team
plans to add reinforcements to make the axis more robust
SLIDE 7
Y & Z CAD
- The pitch of the Z axis lead screw
was 2 millimeters / revolution
- The pitch of Y axis lead screw
was 3 millimeters / revolution
- The motors driving the system
are capable of 200 steps per revolution
- However, since these motors can
microstep, the aforementioned limitation is more than compensated for

Bucket Reservoir
- Bucket reservoir and top
fill plate are no longer required with the syringe/tubing system
○ Both replaced with standoffs
- Syringes can be clipped
to these standoffs
