lmao

[celica40]

l can’t find the real specs of theses vesc’s

@Skyart

00D+ however there are now a few people running the ladder at 20s soooo not sure about the Dx actual lim

what does DRV do?

[Skyart]

It performs the functions of a few chips in one neat and small package

@Zachsnotboard

what does DRV do?

Some discussion here

Cheap FOCer 3 (Open-source, Low-cost, VESC 6 based ESC) (In Development)

I’m back to do what I do best - ask stupid questions! With the DRVless design, I sort of assume that means you have to design your own DRV, or at least something that buffers the switching and switches both high and low, from discreet components. Is that right? If so, will it be more robust than the DRV8301? Is the reason to go DRVless primarily to get around the supply chain issue, or does it make a better ESC? Would this be easier to trouble-shoot if one or more of the discreet components…

[poastoast]

based on what i know, regulates voltage and acts as a gate driver to open and close the mosfets

Can I somehow charge a phone from pins on the Stormcore or should I get buck converter and do it from the battery?

[b264]

“Can” and “should” are two different questions. I would get a buck converter.

[bboybowzer]

Swd aren’t I?

Edit: so it appears 5.3 has started bricking my stormcores. I’ve used this same program I’m pretty positive to flash 5.3.

[superjet700]

Getting my first VESC - Stormcore tomorrow and what do I have to avoid to not brick it? 60d+ new.

[bboybowzer]

Just don’t go to 5.3. Most folks don’t recommend it. I’ve had use cases where I needed it for function.

This video is from a 4wd setup. Canbus cable and the other stormcore were disconnected

Which program did you use out of curiosity?

[bboybowzer]

Vesctool 3.01 on Mac

[jack.luis]

@bboybowzer

Just don’t go to 5.3

@Arch

LaCroix official stance is to update to 5.3 or else you run the very high risk of your stormcore getting stuck in a half-on/half-off state.

[bboybowzer]

I’m currently 3/5 escs that I’ve flashed to 5.3 being ok ish. The 2 last night were unfortunate

[Avi]

The 100dx has phase filters right?
Can it handle 190kv at 18s?

I won’t actually be going that fast on a loaded vanguard with 6354s but it’s good to know.

[Evwan]

Yes, but your motors will be extremely loud. @poastoast is running that setup rn

[Avi]

Good to know. Loud because of the rpm right?
If so that won’t be an issue since I’ll fall off prior to hearing it.

[Evwan]

Just don’t free spin the motors too much .

Set your duty cycle limit lower

Fwiw running high voltage in high kv without a crazy gear ratio to compensate for it won’t give you much of any performance difference. If you were running something like 4:1 on 105s that’s where it helps

[Avi]

How’s 2.78 on 105s sound
Not exactly going for performance here.
