Team Vision for Integrated System Build & Test Phase

Primary goals of this phase:

At this point the full machine has been integrated together and ran. Electronics has adjust the settings in the GRBL to calibrate both axes with the correct scale factors such that the GRBL interprets the output from the GUI correctly and moves the machine as expected. A couple subsystem tests were waiting on the winder to be fully assembled as they were easier to test as part of the assembled system. The winder now runs and we have tested it by wrapping some flat ribbon to emulate wrapping with carbon fiber. All subsystems are functioning as expected and no new major problems or risks have arisen.

Test Results Summary

Subsystem test plans are located here.

Basic test plans for the electrical subsystem have been completed.

Some tests have been deferred to be completed on the full assembly or removed. There are two basic categories of these tests.

Power supply tests

Power supply testing was deemed to be unnecessary. This is documented on the test plan page. To summarize, the concern with the power supplies is that they would be required to provide levels of current that are outside of the specification. This is not a problem, because there is a current limiter that is set on the drivers. This limit is set based on the maximum current of the motors. The current limits set on both drivers are less than half of the current that the supplies can generate.

NEMA 14 Torque Tests

Originally, the torque of the NEMA 14 motor was going to be tested because there is a concern that the motor is not going to have enough torque.

Risk and Problem Tracking

Risks

Update and link risk management table before the review

The electrical subsystem has identified two major risks that we have determined to be the most severe. We plan to address these risks as soon as possibly following the assembly of the integrated system.

Problem Tracking

The current problem tracking document only has one problem in it. We expect there will be more problems that will need to be tracked when the full system is assembled.
