hey skaters, i recently completed my first DIY board. dual 6374 motors, 12s3p battery, 120mm cloud wheels and a bound x-core vesc I got from a friend used. I assembled and programmed it and was surprised when I was able to ride it without falling off. The acceleration is so lacking. Its worse than my friend’s zealot. its worse than my previous meepo v3. I have changed every setting I can think of in the vesc tool and I am getting nowhere. Can anyone proficient in vesc tool or someone else with the bound vesc help me out.
What values have you written to this point?
can you elaborate? do you mean like current values, or duty cycles or something else?
Sorry. Motor max, motor min, batt max, batt min.
motor max 50
motor max brake -50
absolute max 140
battery max 40
battery max regen -18
You could probably push these a bit depending on your motors and cells.
Try:
60
-60
140
45 (if 30Q or better)
-12
To elaborate more, it appears as tho the esc was defaulting the max duty cycle to 40% no mater what was changed. Every time motor settings were rewritten the max duty cycle would be lowered to 40%.
To fix this, we flashed the no limits firmware. And it does now appear that the esc will save the duty cycle settings at 95% but that fix has not elevated the problem of sluggish acceleration.
He’s got a 12S3P P42A pack built by me in the board.
I tried changing motor max to 60 and it made no difference unfortunately bill. and yeah what alex said. I got the duty cycle to stay at 90% but there was no change in the acceleration. It still gets up to 31+ mph but it takes a long time
That’s a meaty 12s3p. Huh.
These ESCs are known to only function well on their included firmware. 3.62 iirc.
im running vesc tool 1.29 and FW 3.65
yeah its an incredible battery. Alex is a master
This is odd. You’re pushing sweet power to those motors.
sweet power
yeah I would think so. I’m at the point where I might just buy a new vesc
I hate the idea that spending more money might be the answer, but maybe grab a Xenith. You will no doubt want to build more than one board anyway.
Maybe try 3.62 fw and if that doesn’t work it’s time to throw it off a bridge?
I fell bad he’s taken the enclosure off like 30 times in the past few days trying to adjust settings and sort the issue out.
it’s time to throw it off a bridge?
sounds reasonable to me, how to I flash older firmware
Believe this is the same ESC. States 2.06 as the target.
