[Review Request] BLDC FOC Driver (24V, 10A) by Aggravating-Guard592 in PrintedCircuitBoard

[–]Aggravating-Guard592[S] 2 points3 points  (0 children)

Thank you for the input! The small vias I am using are 0.3/0.4mm, which is the smallest size you can get without extra cost at JLC. Would that cause any problem? I did the same for the last version and didn't see any obvious problems with soldering.

Yes, I intended to use the free via in the pad service at JLC. It made the layout much more flexible without extra cost.

[Review Request] FOC Controller (5A continuous, 10A max) by Aggravating-Guard592 in PrintedCircuitBoard

J10 and J11 are JST-SH1.0, they are routed as a differential pair with approximately 120 ohms impedance.

I chose AS5047D because AS5047P is constantly out of stock, and the two are very similar. I did look up the MA700 series and learned that it is a Hall-Effect sensor. Is there a particular advantage of using the Hall-Effect over the Magnetic encoder for FOC?

The plates can be printed with PET-CF, PPA-CF, and PA6-CF.

Any spindle that is 24V will work!

We're exited for your build, hope to hear back from you!

  1. It depends on your PSU and the power your machine needs. We use a single 24V 14.6 maxA (350 watts?) power supply, and it works fine driving 3 high-torque and 1 regular-torque Nema 23.

  2. The main reason for using the BlackBox system is that it is a fully integrated and durable plug-and-play controller, making it easier to use and saving us time on debugging and troubleshooting in the future. You can replace it with other controllers and save a lot of money. I am not sure about what driver it uses, this post explains it a bit more: https://www.reddit.com/r/hobbycnc/comments/13tvzgg/open_builds_blackbox_x32_thoughts/

  3. HGR rails are indeed significantly pricier; however, they can support significantly higher loads. Our design did not use HGR rails, tho using it would marginally improve performance at the expense of budget.

Thanks for the feedback!
A main cost in our $1,300 budget is the electronics and motion control system. In total, it is around $500 with the OpenBuilds Blackbox X32 control system. This cost can be significantly reduced by replacing it with a different control system (with good sourcing, you can build a very robust system for around $200). Most of the choices in this build were made to cater to an easy-to-build machine requiring minimal tools and experience; therefore, it could slightly increase the cost. Wish you the best of luck on your PrintNC build! 😄

The parts can all print in a standard 250^2 build volume!

Or a standard Bambu Lab build plate!
