The controller is not responding

Submitted by TheJuan901 on Sat, 2026-03-14 02:03

Hi, I’ve just bought two Maker Base 84200HP units. I’ve connected them and one of them works perfectly, but the other one isn’t responding. The LED lights up, but whether I connect it via USB or to the other unit via the communication port, it still doesn’t respond; I can’t access it or do anything with it. Do you know what might be wrong?

 

Cruise Control on VESC 75200

Submitted by djambobuksne on Mon, 2026-03-09 19:41

Hi, I have a Flipsky FSESC 75200 Pro V2.

I have an accelerator throttle on ADC1, a thumb throttle for breaking on ADC2. My app setting is set to ADC, but I also have a Flipsky display connected on UART.

Everything works perfectly, but I'd like a cruise control button. 

What about ADC15, what about the SERVO pin? Is the SERVO pin an input or an output? Can I wire in another button? 

Should I make an Arduino take the accelerator and break signals and generate a single PWM so I can use the ADC2 pin for cruise control?

KERS system with a VESC 100/250 MKIII

Submitted by Simone Succi on Thu, 2026-02-26 08:28

Good morning :)

Me and my fellow classmate are trying to develop a KERS that should be able to charge and discharge a super capacitor. The challenge stands in using a supercapacitor that start for a 0 voltage condition,which require us to use an external battery to power the logic of our controller. This second battery can't be used to power our motor during the acceleration phase, as well as it shouldn't drawn in any power during the braking. 

Flipsky 75100 pro v2 ADC throttle stopped responding

Hello guys, I have the 75100 pro v2 vesc on my e bike with a hub motor and a twist throttle that stopped working and the voltage stays at 1.47v in setup input tab in vesc tool even though i get 5v between gnd and the 5v wire and a range of 0.8v-4.2v between gnd and signal (ADC1) wire like i did when it was working but still no changes in setup input? 

MXUS 3K 5T Stuttering, Desync, Cogging sounds FSESC 75200 Pro V2 72V

Submitted by djambobuksne on Mon, 2026-02-23 20:05

Hi! 

I have a 72V ebike, FSESC 75200 pro V2 with an MXUS 3K Turbo Motor. It is laced inside a 27.5-inch rim, and at first, I had an MXUS 3K 3T (11.89 Kv) version, which I managed to tune, and it was working perfectly with 200 phase amps. Since the 3-turn motor had a high KV, it gave me speeds over 100 km/h, which I didn't need, and I prefer more torque, so I swapped it for a 5T (7.15 Kv) motor because the 3T would also overheat fast.

Flipsky 72150 outboard cannot connect via USB

Submitted by EddieEagle1970 on Sat, 2026-02-21 16:56

I have flipsky 72150 outboard with integrated esc. I used the Vesc tool via USB and it worked fine. I did a bootload, changed some parameters etc. It connected, and I could use the arrow keys on my macbook to make it spin forward and reverse.

 

However it disconnected a few times, but connected again when switching off/on the batteries. 

Now I cannot connect anymore, the UART still has 5 v and the ADC 3.3 v so I think it is not bricked.

What is the problem? frozen firmware? 

Set current - is it input or phase current?

Submitted by aegidius on Sun, 2026-02-08 05:58

Simple question hopefully.

When I go to set the current to, say, 12 amps (I'm using VescUART) am I requesting an input current of 12A or a phase current of 12A?

I have an ebike setup. I notice that when I ask for 12 amps under a steady uphill load, my input current always reads back at around 7-7.5 amps. I'm assuming this is because my phase current is hitting the 12 amps (I don't have it in my readout as yet).
