Just set it at 85% on all sides, with the other changes you made before reversed to default and it’s very likely to solve every issue you have, minus a few km off your top speed
It’s been around since acks 3.103 so I imagine it’s always been a problem just more noticeable since we’re pushing our boards harder than what was possible with reference 4.12s.
So I ran two boards for a while and I geared for torque with top speeds of 28mph - 32mph which I also regularly hit and pegged.
fw 3.65
sensored FOC mode
dual vesc over CAN
PPM control
switching frequency 20kHz
duty cycle current limit start 100%
max duty cycle 95%
Traction Control disabled.
190kv motors
10s battery
16:62 gear ratio
150mm and 145mm wheels.
I never noticed these issues. and I’m wondering what conditions lead to that differentiation. it seems like I should have triggered the issue.
I only jumped back into VESC proper at FW5.01… I got sucked in by the lure of HFI, and I was too stubborn to back out and admit I’d made a grievous error…
but honestly Unity FW 23.46 had a highspeed wobble coefficient that we never figgered out
MountainBiking has taken off over here in my life, but still E boarding every other day on the DIY job.
I have got a problem with the board though - every now and then (when I hit a bump) the drive to the back wheels seems to fluctuate (less power) which is never a good thing.
I was wondering which part of the machine this may be attributed to?
Could be a loose phase/bad solder joint on the questionable motor / vesc side. Otherwise its going to be hella tricky to track down, what firmware version are you using and which VESC?
