VESC-Tool 2.0 and Firmware 4.0 - The beginning of a new era - (SERIOUS)

More precise detection.

xsynatic · February 8, 2020, 6:52pm

and that causes the sound to be that different? Thought something is broken.

Mainflow · February 8, 2020, 6:52pm

Sorry that was the fault.

Deodand · February 8, 2020, 7:18pm

Yeah it’s faster and more consistent.

@xsynatic Make sure to play with those 123456 and the plotting buttons up at the top right of the plot to change view modes.

@rusins you are correct that setting it more than 40V at 10s won’t do much, that voltage actually seems way above what you need for a 6374. Maybe the kV makes a difference. I’ll have some lower kV motors in the mail soon. What pwm freq do you have set? I think the default is now 25 kHz? Maybe turn it down to 20 kHz (motor→foc→advanced) you will see more excitation of the coils at lower pwm freq (louder too)

Don’t know; I’m away now, so don’t have access to the board.

Deodand · February 8, 2020, 7:20pm

Thanks for testing this stuff out and reporting back!

xsynatic · February 8, 2020, 7:41pm

Yup, did that with no effect. Enabled all, disabled all, reset it, rebooted, restarted, de and reactivated RT data.

I think i wait either for the vesc tool 2.03 or until metr supports the 4.1fw

@Trampa when are we getting a reasonable stock numbers of the battery current max (instead of 99Amps)?

Also the fw version seems to be bugged.

The tools said the newest available version is 3.66 (tool version 2.02) if i update regardless i get the latest 4.1 fw.

@Deodand
I just tested HFI on a prototype flipsky motor (has convex magnets) on my trampa VESC 6, it only generates torque in one direction; this is expected, correct? If so, will there be an easy way in the future to flip this direction? Right now I do it by swapping two phase wires and toggling the “invert motor direction”.

Also another thing, “sample in v0 and v7” appears to break on firmware 4.x on non trampa hardware. I don’t understand why since all VESC based ESCs use essentially the same power stage and signal conditioning hardware.

I definitely got scared there the first time I saw this too.

Santino · February 8, 2020, 11:34pm

My wife use two destroyed unsensored Maytech motors, I followed @Deodand video to instal HFI; the result it is incredible, smooth start, almost no noise, increase confindence to her and she is ridding better that ever. This is a great change for both of us…Thank you so much guys!

Murloc992 · February 8, 2020, 11:41pm

When I hold the brakes it makes the HFI whine. Does it mean we finally got handbrake? Can anybody confirm?

Mainflow · February 8, 2020, 11:42pm

Test it on a slight hill.

Murloc992 · February 8, 2020, 11:42pm

I have no means to test it right now. Winter, wet a f, recovering from a shoulder break.

Mainflow · February 8, 2020, 11:43pm

Have a good heal bud.

Santino · February 9, 2020, 2:58am

Yes, hand break, tested…

Trampa · February 9, 2020, 9:09am

It’s smart reverse. You can use smart reverse to hold position on a hill.

Murloc992 · February 9, 2020, 9:10am

So it’s a tiny bit of smart reverse? As I have set my Control as Current No Reverse With Brake.

@Trampa I’m trying to upload the new 4.0 firmware with the VESC 2 tool. I previously had ackmaniac version 3.103 on the VESC. When attempting to get the new firmware I keep getting an erasing buffer error. Not sure how to get around it any advice would be great.

xsynatic · February 9, 2020, 9:42am

I had the same problem. I used an older version of the vesc tool (1.08), flashed it’s fw and then used the latest tool for the update again.

ahrav · February 9, 2020, 9:43am

You my friend… words can’t explain how grateful I am. Spent about 3 hours screwin around with this thing. Thnxxxx
