Wand Displaying Wrong Voltage %.

Submitted by WastedYouth on Sat, 2021-10-23 17:37

I'm new to eSkate, & updated the firmware on my Trampa board (2 VESC 6) without saving the config file.

After using the Motor Wizard & re-connecting the Wand, the Wand is reporting 10% less battery voltage than actual.

With the batteries @ a storage charge of 55%, the Wand is displaying 45%.

Any idea why this would be happening?

VESC "underpowered" vs Kunteng Controller experience

Submitted by andyw2005 on Thu, 2021-10-21 23:54

Hey all,

Appreciate that VESC's are usually in the eBoard domain, but thought it interesting to take a punt on a MakerX 75/100, none the less, on my custom e-scooter (M365 pro front motor)

Though dead silent (FOC). The acceleration is way behind the kunteng's despite following multiple instructions, setting up a thumb controller and understanding the basics.

Controling two motors with Dual FSESC6.6 in two directions

Submitted by Rafal on Sat, 2021-10-16 13:47

Hello,

I am trying to build a sumo-robot using Dual FSESC6.6. and I would like to control two motors in two directions. With the application I can control the motors only in the same direction.
What shoud I do or what should I use to control both motors in the opposite or the same direction whenever I want?

Kind regards,

Rafal

Assistance for VESC controlled electric bike

Submitted by Motch on Tue, 2021-10-12 05:40

Hello,
So for my High School subject, I have built an electric bike and planned to use a VESC Controller to control it.
I have gotten into the final steps and now need to program the VESC to function correctly, I haven't found a good explanation of how I would do this for something that isn't a skateboard.
The motor is a Turnigy Aerodrive SK3 - 6374-149KV Brushless Outrunner Motor

Starting rotation by changing duty cicle- current increases shortly (ms) and dcreases immediately to 0A

Submitted by simon_snow on Wed, 2021-10-06 22:15

Hello together, 

I am new in this forum. I started using the VESC because I´ve designed an own 3D-printed Motor. 

I have following problem and really hope you can help me. 

After I made the motor setup (which worked very well) I want to start motor rotation by changing the duty cycle (buttom left). When I push the play-button the current goes for just a few ms to nearly 0,05A and then immediately decreases to 0A. It can´t be a short cicuit (don´t know if this is the correct word ;) ) because otherwise a correct setup would not be possible....

What is limiting the speed?

Submitted by ProgramThyself on Wed, 2021-10-06 20:07

I have a VESC 6 MK IV with 5.02 firmware and recently upgraded the battery from 10s to 13s (above spec, I know).  Near the top speed that I expected for this  battery (30 km/h), the VESC keeps cutting out (see plot).  The dark green trace often rises to 31 km/h and then the current drops to 0 without throttle change or a fault.  Is there is a setting I forgot to change?  ERPM at 35k is far below the 81k limit.

Cannot use BLE in combination with Custom App anymore after upgrading

Hello everybody,

I'm trying to update the FW of my VESC Hardware Version 4.12 from 3.63 to 5.02. Normally this isn't a big deal but the thing is, I have a custom app which integrates a cruise control in my speed knob.

So I followed this explanation again:

Wheels only rotate about a quarter of a turn

Submitted by Appearance on Mon, 2021-10-04 17:57

Just looking for some advice. Configured motors on the VESC and all semeed well, they spin when testing. Unfortunately, when I try to accelerate using the remote (board is upside down), the wheels just turn a quarter, stop, and the remote beeps. Links of setup are attached. Advice would be great!
