What did you personally accomplish this week on the project? Give files or photos that demonstrate your progress. Prove to the reader that you put sufficient effort into the project over the course of the week (12+ hours).
This week I made a great deal of progress. On Monday I wrote a basic Arduino sketch to test the limit switches we received and ensure they work as expected. This was successful. We’ll be using these for calibration.
I also spent some time designing the laser cut file to engrave our table. We’ll be purchasing a large piece of 1/8 in plywood, sawing it down to the right size, and engraving it using the IDeATe laser cutters.
I have begun by structuring all my code into libraries. I now have a stepper motor library. I tested this by writing an Arduino sketch to step both motors synchronously forward or backward by a number of steps entered by the user over serial input. This test was successful. In this test, we discovered that we will need one power supply for each motor driver.
Finally, once the second belt arrived Trey and I tested movement of the gantry using the stepper motor library. I wrote an Arduino sketch that let the user move the gantry by a positive or negative number of steps in the x and y direction sequentially. This test was also successful.
Is your progress on schedule or behind? If you are behind, what actions will be taken to catch up to the project schedule?
I am right on schedule.
What deliverables do you hope to complete in the next week?
I need to finalize the gantry library with better calibration for the number of steps per inch, so that we can have more accurate and precise gantry movement. I’ll also be helping Trey with some physical assembly.
