Well, your ESC has no Bootloader I guess, and I woud simply upload it via VESC-Tool. Worst case outcome if you mess up the botloader section: you need to buy a 3€ ST-Link from Ebay.

You don’t need it if the bootloader upload works.

  1. Download STlink Utility (http://www.st.com/en/embedded-software/stsw-link004.html)
  2. Download the last FW from Benjamin for HW4.12 http://vedder.se/forums/download/file.php?id=6
  3. Install STlink Utility (it is inlc. drivers for the STlink)
  4. Connenct the STlink to the Vesc with only 3 Pins SWDIO --> IO, GND --> GND, SWCLK --> CLK (NEVER connect the 3.3v pin, RTS no need)
  5. Power on the Vesc
  6. Open STlink Utility
  7. Open the tap TARGET and klick Connect --> the program show you the infos of your VESC
  8. Open the Tap FILE and klick open --> search for the file “VESC_default.bin” and select (base address is 0x080E0000)

Everything is working excellent now, i really like this new vesc tool, much easier to set everything up, now i can teach my son how to work this new vesc tool, the older software was difficult for him to learn.

I really want to setup F.O.C. but the vesc tool has my battery currents at 34v start cuttoff and 31v end cuttoff, is that safe for foc on a turnigy 6374 149kv?

559

The battery cut off settings are not relevant for FOC but the problem is the maytech hw, you should run BLDC mode only (I tried FOC and can’t recommend it)

Thank you. What was your experience with foc and maytech vesc, what kind of issues did you have? just curious.

561

Multiple faults and dropouts for several seconds everytime when hitting the brake (even with no load).

562

Exactly the same, in blcd rocks

I upgraded my focbox to 3.34 but now having problems with motor detection in bldc mode. It is spinning up the 6374 190kv motor but failing with bad detection result received. Anyone else run into this issue?

565

Thank you for that.

Hallo Guys…

Being out of the game for a while. With the newest vesc tool /firmware. Is it safe now to run FOC mode on my focboxes ? (10s build - sk3 6364/190kv) And is the foc motor detection working now for focbox ? Last time i tried , it didn’t Thanks…

567

Bare se at få den smidt i FOC inden onsdag :grin:

568

@DK-Odense Det var også planen, så det kunne testes / prøves :slight_smile: Men hvis det stadig er lidt beta. Gider jeg ikke ændre endnu, når jeg ved nuværende spiller for mig :slight_smile:

569

Try to raise the low duty current from 0.05 to 0.1

570

Good news : FW 3.34 is now commited on Github. :slight_smile:

Hi, does anyone have the PCB Gerber files for the VESC 4.12 they are willing to share with me? I’m trying to build my own vesc but cannot find any of the PCB files

Thanks.
