Typos can destroy expensive hardware; please be careful!

Typo on the post, not the vesc tool lol. I triple check everything there

ShutterShock · February 21, 2018, 1:36am

yep exactly, I have no idea why. It won’t even get through the motor detection in BLDC, it fails every time.

ShutterShock · February 21, 2018, 1:37am

Maybe I will try this. I used the same config as on my TB VESC’s so I figured it would be fine, especially since it works in FOC, but this isn’t really a hard thing to check either.

Here are the firmwares https://theboardtech.com/wp-content/uploads/TheBoardTech_VESC_FW.zip

And here’s how you do it

I downgraded to ackmaniac 2.54, now using his modified BLDC tool instead of the newer ESC tool.

Thanks anyway!

GrecoMan · February 21, 2018, 2:27pm

and you got it to detect?

Achmed20 · February 21, 2018, 2:59pm

have the same problem with the curretn VESC tool. its jsut completly random. sometimes its my left motor, sometimes the right one and FOC works all the time … . that used to be the other way arround ^^

Apolo · February 21, 2018, 3:11pm

Yep. Literally zero problems with ackmaniac bldc tool 2.54

Apolo · February 21, 2018, 3:14pm

Got everything working with 2.54. I guess the vesc tool is just bugged.

One problem solved, another arises. My Nano X I’ve been waiting 3 months for doesn’t work. Mailed it to @barajabali per enrtion support’s request. Hopefully I’ll get my replacement soon.

SORRENTINO · February 21, 2018, 3:19pm

So I had the same issue with the Vesc tool. Ill I had to do was turn up D to .1 or .12 like @Brianr058 mentioned.

TarzanHBK · February 21, 2018, 3:30pm

@Ackmaniac do you know whats wrong with the vesc tool here?

Apolo · February 21, 2018, 3:43pm

Also, is there a 3.xx version of your firmware incase the esc tool decides to work?

Luuke · February 21, 2018, 5:32pm

Same here!!

Apolo · February 21, 2018, 5:52pm

Guys I just tried BLDC detection again with the vesc tool today and it worked. I changed nothing lol.

VESC Boot Loader Installation Tutorial - #7 by Riako - ESK8 Electronics - Electric Skateboard Builders Forum | Learn How to Build your own E-board

Cause I need to use my fox with VESC TOOL, when I flash my Fox with stlink and last hex files from Benjamin, it upgrade fw to 3.34. Is that the one you test @Apolo ?

And just to see clear about of it, witch fw and tool is the “best/trusty” to use with a Fox actualy ? ?
