Today, my supervisor asked me to 3D print several type of cube to test the performance of the 3D printer. Using the 3D printer actually was a troublesome for me. This is because, to get the setting right for the 3D printer required multiple of tries. Without correct setting, the printed filament wouldn't stick to the bed, warped and worse case, the first layer of the printed filament move causing rubbish outcome. Another case was, the nozzle being too closed with the bed and blocking the filament from coming out. It took me the whole day to get suitable setting. At the end of the day, I only managed to print a small hollow cube which took about 35 mins printing time. Although I did managed to print a cube, but the quality of the print was still not satisfying for me as some part of the cube which supposed to be edgy becomes curved. En Taufiq also request me to write a simple user manual for the 3D printer that I work with.

Today I assemble and did a bit modification on the line following and ball throwing robot. I'm using PID system so I'm currently doing endless experiment to find the best gain, Kp, Ki and Kd so that the robot can follow line more accurate. At this rate, the robot had no problem when routing on 90° sharp turns and curve, but it is not smooth enough and occasionally jerking. A part from that, the throwing arm works greatly. The only things that need to be improve is the motor specs that was used. Apparently, the current motor did not have enough torque to throw ball far enough. I already forwarded all of these issue to my supervisor for him to review. Later that day, I did a pendarfluor lamp installation at a bundle shop nearby. They request to install 2 lamps at the back of the shop as that area didn't get enough illumination. Amos assist me throughout the installation work.
