Integrated System Build & Test
Table of Contents
Team Vision for Integrated System Build & Test PhasePrimary goals of this phase:
- Complete mechanical subsystem assembly and test.
- Complete formal testing on the electrical subsystem.
- Assemble subsystems into an integrated system.
- Test the integrated system against engineering requirements.
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 testsPower 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 TestsOriginally, 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
RisksUpdate 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.
