This week, I cut out the main machine body of ACE, made of mdf. After consulting with a person working in Techspark, I realized that the thickness of does not need to be overly thick. So, I decided to use a 3mm mdf, which significantly reduced the overall weight of the machine. So, I think we can continue using the motor shield we have for now.
I have confirmed that the machine does spin properly, within the latency bound we have set as the design requirement. Right now, I have temporarily put the pieces together in tape, but they will soon be glued together. Once the dispenser gets printed, we can try placing it on the designated space and see if everything works out.
Roughly on schedule, with some parts ahead and some parts behind. It was unexpected that our order for the SD card got canceled.
