Need help: encoder shows 9.6 rotations per 1 motor rotation (9.6:1 gearbox)

Forums:

VESC 6 mk2, 11 pole pair motor, sin/cos encoder on motor shaft.
9.6:1 reduction gearbox between motor and output.

Problem:
After FOC setup, rotating output shaft once (motor spins 9.6 times) shows ~9.6 rotations in rotor position display. VESC ignores gear ratio.

Tried:

  • Set Motor Poles = 22

  • Changed "Encoder Ratio" (0, 9999) → no effect

  • Re-ran sensor detection

Hi, 

Newbie here. Been trying to solve an issue with VESC IMU not showing up on the VESC Tool. Specifically, the IMU detector is not detecting the IMU. Checking the terminal - "LSM6DS3 Address A failed, trying B (rx: 255) LSM6DS3 Address B failed (rx: 255)". Could anyone help me solve this issue?

 

VESC Tool TCP server, how to start connection to VESC ?

Hello, I need to access via internet to a VESC which has a wifi / uart interface (ESP32C3 based, simply replicating the UART to tcp byte frames) and a wifi client connected to a RUT240 Wifi/4G router.

This interface connects to VESC Tool TCP server at my office : I can see that the TCP connection is established :

Setup: any VESC, Flipsky (or any) receiver, VESC WAND Controller and Vesc Tool 6.06 for android. This is a new bug, not seen with VESC Tool 6.05:

- connect VESC Tool android with vesc over BLE. SEtup Motor. This works perfectly.
- use NRF quick pair to connect VESC WAND Controller. Now VESC WAND works as usual, pairing successful
- disconnect VESC Tool 6.06

I bought a second hand Trampa Mountain Board with two VESC 6 Esc's with firmware 3.54

I searched for the VESC Tool 1.08 which could run the firmware 3.54 but it is only available for MAC's. I have to replace the Battery settings in the VESC tool, but I can not getting the VESC tool to connect correctly to my ESC's. I tried earlier Version and newer and newest Versions, but every time the same messages appear >

The connected VESC based ESC has too old firmware. blah blah blah

Hello. Is it possible (how) to get a turn counter : just to know how many turns has been done and a reset function. I would like to get that from UART so that I could use it else where.

May be it's more in the firmware ?

Thank you for any assistance

 

Battery profiles?

Submitted by ahagge on Mon, 2025-09-01 16:36

Forums:

Is there a way to create "battery profiles", ie. switchable profiles which include battery parameters such as chemistry, configuration (10S3P), capacity, max discharge rate, etc.?  I can't find anything in the profiles that concerns battery information, only motor information.
