You mean don’t limit the speed at all? I don’t really need it for myself but I thought it’d be good in case a friend rides it.
u just had this issue @xsynatic , it was something to do with the forward and backward speed isn’t it?
no, limiting the erpm will lose braking ability once erpm exceed that set number, so its more dangerous
That’s not what I mean.
I mean this, and, more specifically, only on VESC.
Gotcha. Is there another way to limit the speed in case I want to do that?
I would recommend going the hardware route of changing direction. Vesc tool changes the direction, but not the correlating speed settings.
So your working Motor for example has
Forward 30mph
Reverse 10mph
Your inverted motor needs to have
Forward 10mph
Reverse 30mph
And since this is a big mess i would recommend you change the phase wires so no firmware trickery is needed.
Okay thanks, that’s what I figured from my testing, but I wasn’t sure if I was missing a software option for inverting the speed settings.
Duty cycle limits are much safer imo
So those Vesc tool profiles change the duty cycle to limit the speed or did you calculate the max duty cycle for each profile? I was attempting to use the Metr modes but it looks like those modes adjust the max erpm which is why I assumed that was how to limit the speed.
Edit: My bad I see you were showing the inverted limits, not the profile speed limits.
The vesc tool ones as well as metr limit the ERPM, not duty cycle.
I personally haven’t bothered to use and calculate a duty cycle limited mode because for me erpm works perfectly fine.
I either have full speed or 6kmh and since the 6kmh mode only is active while not riding, using the erpm one is fine.
Thanks @b264 @xsynatic @ShutterShock @frame! Duty cycle limits are working perfectly and are ignoring the inverted motor.
Nice! Glad you got it figured out
I think the problem comes with erpm mode if you roll past that erpm limit you don’t have brakes
Don’t quote me bc I haven’t tried it before but I think? that is right? @b264

can i use my laptop usb c charger for a speaker with usb c (speaker says 5v input and uses one of those small phone usb c cable)
Depends on if your laptop charger uses a standard or not
Is it USBC PD?
Also, sometimes, USBC PD won’t charge normal “usb c” charging devices
I think so too.
Duty cycle is the way to go if you actually want a usable limited speed mode. If you do it like me erpm is fine.
Not sure how it handles higher voltages. I personally wouldn’t go over spec.
depends on if ur laptop charger can output a lower voltage, some can’t do that. most modern laptop charger i saw from apple / asus / samsung can auto output 5v, but u should check the prints on the charger, it should say what range or set voltage it can do
Anyone able to recommend for or against Mach bushings? I need to get a few to try out and they’re so cheap they’re looking tempting
