Hello,

I'm trying to power a ME0708 DC Brushed motor, with VESC 6. No matter what setting I change I can't get it to pull more than 20 amps. When I do a direct motor to battery connection it draws 40 amps. Is the 20 amps a built in safety limitation in the code for the hardware? If so, what is the DC motor current rating on the new VESC 75/300 controller?

Thank you

Hello ,

  I diy a VESC6 board and double checked schematic and PCB, it looks good.

Hi, I am trying to build a remote control lawnmower using 2 x MY6812 24v 150w motors (https://www.motiondynamics.com.au/united-my6812-24v-dc-150w-2750-rpm-ele...) in a skid steer configuration. I need an esc that will control both motors forward, back, left and right like the guy in the following link but with bigger motors, and work off an R/C receiver.

I have a two-VESC longboard that I want to control via UART. 

Setup:

HI all 

Recently took delivery of a 2019 Trampa MTB. it's awesome but i'd like to make some adjustments to the vesc to see if I can change the way the board pullls away and accelerates. The guys at Trampa told me I could get the VESC software  and put it on a phone that would then be abe to adjust the VESC over bluetooth.....?  So my questions are this 

1.what phone would i need? 

2. Are there instructions here or anywhere else on how to get the software onto the phone? 

I really like what you are doing, the hardware and software integration is really phenomenal. I am a mechanical engineer and I admire all of the hard work and dedication you have put into this project. Being kind of new to Rasberry Pi and Raspian and also being a software challenged ME, for the life of me I cannot get the VESC tool to load. I tried the Platinum and Free versions (I know they are the same, I had to try) and I cannot get the software to start. I got the BLDC tool to start, but the VESC isn't giving me anything. 

Hi,

Is it possible to set the deadband on ADC1 and ADC2 differently?

This might be a VESC Tool feature request.

Thanks!

Hi!

Are there any tricks to improve low RPM torque in FOC mode? It seems that very low speed torque is better in BLDC mode than it is in FOC. I'm using hall sensors. What parameters should I try to tweak?

I'm using my custom HW with 200A motor current so maybe there are some parameters that need scaling from their defaults?

Thanks!

Hi all

I'm using a VESC 6 for position control and I have noticed that every time I boot VESC tool up, my position readings are different from what I've been getting before. I think I've pinpointed the issue to the fact that the encoder angle offset is different from the previous reading. 

So is the angle offset being different after every boot up normal, or is there something up? Do I have to go through the encoder detection procedure every time I boot VESC Tool up? Any clarification on this would be greatly appreciated.
