Help me solve my seemingly unsolveable problem.

I once again summon @Trampa

Trampa · March 17, 2021, 12:09pm

Unity is @Deodand

xsynatic · March 17, 2021, 12:19pm

sure, but it’s not just the unity that shows this behavior.

Trampa · March 17, 2021, 12:21pm

But it’s the software in combo with the HW…

Dinnye · March 17, 2021, 12:22pm

Not only unity

xsynatic · March 17, 2021, 12:25pm

The issue does not happen on UnityFW
It does not happen on Vesc fw 4
It does not happen on Vesc fw 3.66
It does not happen on Vesc fw 3.65
It does not happen on Vesc fw 3.61
It does not happen on Vesc fw 3.103

It does happen on vesc fw 5.01
It does happen on vesc fw 5.02
It does happen on vesc fw 5.03

on 4 different motors
3 different vescs (i can test a 4th one if you want)
and on 2 different remotes.

I’m not sure how i can use this to fix my issue.

Did you only test it on the bench? It is a current controller and you need load.

xsynatic · March 17, 2021, 12:29pm

Yes, as i’m not really comfortable running a setting that could launch me at full speed.

Did you watch the video?

Trampa · March 17, 2021, 12:36pm

To dig down to that it would be good to spin one wheel only with the standard detection.

xsynatic · March 17, 2021, 12:38pm

Do you mean this as standard detection?

Trampa · March 17, 2021, 12:39pm

setup motor FOC, load default setting, run detection. Then do not change anything.
Then use keyboard keys to spin up the motor.

xsynatic · March 17, 2021, 12:52pm

these are wrong again.

grafik

Activated the keyboard and used the current control

smooth without problem. Nothing else is touched, no input was configured or anything else. Duty cycle current limit start is at 1.00 as it’s the stock setting.

Trampa · March 17, 2021, 12:53pm

And if you now set it to 0.85?

xsynatic · March 17, 2021, 12:54pm

same thing.

Smooth without the crackling.

If i were to use the remote it would come back

Trampa · March 17, 2021, 12:54pm

Try it.

xsynatic · March 17, 2021, 12:59pm

at 0.85 and a remote it’s back

spikes are when the issue appears

now setting it back up to 1. (duty cycle is still at 0.95)

and it’s as smooth as it is with the keyboard control

Trampa · March 17, 2021, 1:01pm

Can you cheat the input wizard for me, so that 90% throttle is 100% throttle?

xsynatic · March 17, 2021, 1:08pm

same result.

issue at 0.85 and no issue at 1

Full throttle on the trigger was set to 90%

Just to clarify 100% on the trigger should be 90% in the vesc tool or 90% trigger should be 100% on the vesc tool?

Edit: same result.

Now i’ve tried 100% throttle translating to 90% signal and 90% throttle translating to 100% signal.

Trampa · March 17, 2021, 1:16pm

Do you have another remote?
