In this project update, we will tell you about the electronic testing we ran on Goliath CNC for electromagnetic compatibility and we will share the electrical check we conducted to make sure Goliath is ready for North American voltage. Finally, despite the global situation, we are still receiving and testing the quality of new components for the mass production.
Before we get started, we want to inform you of the unfortunate situation in our country and the consequences it has on our work. Since our last update, the covid-19 outbreak has spread worldwide. Above all, we wish you to be healthy and we encourage everyone to take all the necessary actions to stay safe.
For our part, since March, Italy is on lockdown, the government imposed a national quarantine on response to the growing outbreak and closed all the companies working on non-essential goods, so our whole team must work from home. Some of our suppliers are operational, but many are closed, due to the lockdown. Unfortunately, the entire production cycle across most suppliers will be delayed.
In the past weeks, we received some components for the mass production of Goliath CNC. We collected the samples of the dust bin from our injection molding supplier, the firsts with a single plastic shell. Here you can see the dust bin:
We received from the manufacturing process the gasket of the emptying door on the dust bin. We ordered different springs, we will mount them on the sensor calibration guide one after the other and test them. Finally, we collected the reel, to support the spring inside the sensor and the funnel, through which the wire passes on the sensors.
Before the lockdown, we conducted a full day of testing with our supplier for electronic, a necessary step before bringing a product to market to check that the machine will work fine in real-world conditions.
The first test we ran was the measurement of the electromagnetic compatibility with its environment, required to control that the emissions generated by Goliath CNC comply with the legislation. In all the conditions we tested, the outcome was good. In a second phase, we conducted tests to verify that Goliath CNC does not absorb the interferences in the environment and gets damaged. Even in the worst conditions, the robot works fine so the results are satisfactory on that side as well.
120 volts version
Lastly, we tested the 120 volts version of Goliath CNC to make sure it is ready for North American voltage: we needed to check that the machine does not overheat and that everything works well at this voltage. We ran the test by cutting the Edie Table from the Opendesk catalog, measuring the temperatures frequently in different points, both outside and inside the machine.
As we expected, the temperatures are a little bit higher compared to the 230V version, but only one component reached a significantly high temperature and this increase does not reflect on the temperature of the internal components, therefore we can say Goliath CNC passed the test.
Next time, we will update you on the software development and we hope to receive other components to move forward with the manufacturing process.
Stay safe everyone!
All the best,
Lorenzo, Alessandro, Davide
and the Springa team
