Well… Hopefully wobbly motor speed is too.
Because if not @Trampa will say it’s your fault anyways.

I can’t imagine any scenario where software induced speed wobbles are better than hooking up a sensor.
I didn’t say the HFI had to come from Trampa. Time to start the research into what’s possible.
Prolly not, and if he did it would only be in Trampa VESCs. I’ll just keep using Ack until something better comes along. Features aside, my stuff works… And I even have reverse .
You know, private data can become public once the lawsuits come rolling in. Unless he isn’t selling VESCs with the latest FW, which would be telling.
Current mode with Wand remote (NRF remotes don’t have many control modes like PPM).
I’m not 100% sure yet if it’s the FW4.0 but I think so. After downgrading to FW3.62 and testing on weekend I should know and report back here. Maybe I need to downgrade the Wand as well
please test for all our sakes, both @DavidC and @Titoxd1000 have reported similar issues that were resolved by downgrading
Same happens to me, the board wobble in a strange way, can not push the throttle harder because it is getting quite dangerous. I have 2 Vesc6+, canbus, 6380 TB motors, miniremote PPM…It is the same as @rich described…
@Halbj613: Check you USB cable. Those issues are often USB related. You can try a TCB bridge and see if you get the same issue with wireless connections.
Whobbles: We did some tests this morning and tried to replicate what some users described here:
Benjamin will publish a FW update with a lower standard Time Constant value.
Currently the detection uses 4000uS. This affects the KP and KI value on motor detection.
For everyone experiencing a wobble at a certain RPM, please use 1000uS Time Constant during detection.
Quick guys, Ben’s pusing a change that’s mostly untested on many setups to the stable main branch. I would recommend updating immediately for the latest and greatest . . . If you can get to the vesc tool that is
anyone else start getting over current faults after switching to HFI? Can’t even go past 50% duty before cutouts start happening… also is there any reason for HFI to be active when braking? I never had cogging when braking sensorless, but HFI braking feels a bit gritty/not smooth
HFI is only used on slow speeds, low ERPM. As soon as Back EMFs are good enough to track the rotor, HFI is not used any more. This is similar to Sensors.
ABS over current is in most cases related to the motor resistance value or other motor detection parameters or it is HW related. You can try the tweak I described above, set down the time constant for detection. If you had a working setup, you can go back in FW, do a detection, backup the detection values and restore them after updating to the latest FW. There is a backup option in VESC-Tool now.
Where are these files stored? I wasn’t able to find them.
They’re on the TRS-80 in the garage.
Desktop: NEXT to FILE >> ConfBackup.
Mobile: First page, all the way down at the bottom of the page.
Location of the file: I need to look that up for you.
I recall trying the newer vesc tools just prior to 4.x and my detected max amps were always way low, like 21A or less. I thought this was odd since on Acks I’m doing 80A/120A no problem. I also ran into stuttering and overcurrent faults. I may try copying over the detection parameters manually, or I may just stick with the stable branch for now… those wobbles are a little crazy looking.
Ackmaniac?
Yep. 5char
Next time perhaps do this kind of testing, and more, before one pushes live code to a codebase that can literally injure people.
These are dangerous and negligent coding practices. Sorry if that’s a jagged pill to swallow but it’s the truth.
Frank, may I please direct you to this thread, again, as it couldn’t be more relevant if I tried:
Open to having the conversation if you’d like to have it, but at this point we’re moving forward with a community tested ‘stable’ fork.
Ack seems like the easy answer to everything, except it apparently doesn’t work well on hw6
