Some of the earliest CC1 units were shipped with BFC feeder controllers that had quality issues. These controllers may experience a 24V power short circuit fault after being powered on for an extended period. Typically, this fault causes one or more BFC controllers to stop working (the power LED does not light up after power-on). In severe cases, the short circuit may also blow the fuse near the main board’s power input.
The cause of this fault is a short circuit in capacitor C9, which appears to be a quality issue resulting from improper storage of the component. Since the functional testing phase for CC1 units only involves powering on for approximately ten minutes, this short circuit fault was not initially detected. As a result, some machines with problematic BFC controllers were still shipped.
For subsequent CC1 units, some were equipped with BFC controllers produced earlier, while others had the fault point manually repaired, reducing the probability of quality issues occurring.
Recently, I have some new stock of BFC controllers.
Therefore, if your machine experiences a BFC short circuit or even a blown main board fuse, please send an email to [email protected] or [email protected] to request a replacement.
As long as there are no shipping restrictions, the replacement will be completely free (free shipping). The basic principle is that your machine will be restored to fully functional.
Sorry for the inconvenience and delays caused to some early users.
Hello, I received the CC1 machine this week, I haven’t had a chance to use it yet, do you think it would be necessary to change that capacitor C9, as a precaution?
Hi,
The recent CC1 units you’ve received should all be functioning properly. This issue primarily occurred in orders placed from July to August through Aliexpress and Shopify Store, for some of CC1 units shipped before the problem was identified. After confirming the issue, I completed orders using some earlier normal BFC and later manually repaired ones.
Your CC1 should be the repaired one or the latest maed ones, so it should work properly. If you encounter any issues with BFC or other hardware in the future, simply contact us via email to request replacement of the damaged components.
Fantastic! I was debating removing the Y extrusions and replace them with longer extrusion along with longer rails on a CC1. Thinking I could make it considerably larger for more feeders but wasn’t sure if the feeder controller could handle it. That’s fantastic!
Yes you can give it a try.
The CC1 has a COREXY structure, and with the increased size, the tape’s elasticity might be slightly greater, which could lead to a minor decrease in repeat positioning accuracy.
For the A1 structure, the impact on precision due to increased size is smaller.
Yes, that is also a good solution. Actually, I estimate that the actual precision impact is within an acceptable range.
You’re welcome to share the modification process and results later. Perhaps others would also want to enlarge their CC1.
Due to packaging size limitations and the higher shipping costs for large volumes, I currently can’t easily increase the size.
Side side note I have a almost working feeder management system! I’ll post video and share files eventually.
I have considered using simple scripts to accomplish some automation configurations.
Is your feeder management system an OpenPnP plugin or an independent external program? What are its main functions? Looking forward to some demonstrations after completion!
just wondering about this one.
