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?

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 :

Forums:

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
