4. Test Plans Code Test Range
Goal: Draw a horizontal/vertical straight line 6” and 12” long
Test: Start the pen equidistant from each motor. Calculations for line length, and run test.
Results: Pass/Fail. (Straight or bowed)
Range
Goal: 36”x 44” (Dead zones create a smaller workspace)
Test: Move the pen sled to the four extremes, mark location, and measure.
Results: Size of the possible workspace

5. Test Plans continued Shapes-Code Test Speed
Goal: 180 in/min-(30 in/10s)-(3 in/s)
Test: Draw a straight line 30” long and measure the time it takes.
Results: Pass/Fail. (fine tune the motor speed until desired speed)
Shapes-Code Test
Goal: Draw simple shapes (square, circle, triangle)
Test: Test the code using the CNC Pen Plotter. Mark the location for each corner (change in direction) and figure out if the shape is drawn is correctly.
Results: Pass/Fail (is the shape the correct shape or is it shaped differently)

6. Analysis Meets requirements Engineering Specifications:
Plotter plotting at a speed of 3 in/s
Can draw a line 40” long without deviating (bowing) by more than ½”
Accuracy of line length within ¼”
Plotting workspace 36” x 44”
