Today, we work on improving and updating our programming on both the motor control and led control. We have changed the condition statement and code for the movement of the motors in the programming part. We have added an end-switch to the x and y axis so that when the plate holder and the x axis reached the end of the trail, it would know that it has returned to the original point. 

void setup() {
  // put your setup code here, to run once:
  pinMode(2, INPUT);
  pinMode(3, INPUT);

void loop() {
  // put your main code here, to run repeatedly:
  int sensorValue = digitalRead(2);
  int sensorValue2 = digitalRead(3);


We have also fixed the holes on the x axis and recut it with the CNC. even though we have met some problems during the process, we still manage to get it done. 

We 3D printed the parts of the two axis(gear holder, belt holder, etc) and fixed up the problem that we have faced before such as the height of the gear holders.
