throttle set up

Ive got a makerbase 75100, wired it up and set it up as best I can, I must say I have used all sorts of motor/servo controlers for cnc machines,and this vesc stuff is the worst I have come across for tutorials!!

Anyway, ive got a standard ebike 4.5 v throttle linked to adc1, it works but just like a switch either on or off.

I can only assume its because in the input setup it wont allow you to go above a 3.3 input voltage, the output is 5 volt, how do i get it to accept 5volt input?

Regards

Tony

ok set up rt app and its reading 3.6 or 100%.

also ive noticed that if you disconnect the any of the throttle wires the motor runs flat out, which surely cant be right? I would have thought it would cut out.

so vdcc set at 5volt

connected to 5volt not3.3 contact

is outputting 5 volt to throttle

throttle output pin is reading 0.8 v - 4.5v

on the vesc set up in throttle mapping it wont allow me to change the adc above 3.3 v

There are many tutorial videos on youtube and in forums. Just use 3,3V (VCC)instead of 5V. The ADC1 input is only made to read 3,3V max. If you go above 3,6V (default value) you will get a fault and it will cut power. If you cut a cable adc1 will be floating. You can connect a 1-3kOhm resistor between ADC1 and GND close to your Input Pins to prevent the problem.

oh there are plenty of tutorials if you have a degree in computer engineering, but nothing of any use to the normal person.

even worse i switched it on and it wont come on no blue light , just an obvious burnt out smell.

oh and the seller refuses to take it back.

great

what a piss poor product

I wouldn't recommend makerbase to anyone.  The only interesting thing about them is I see one of their employees actively posts here:

Lots of issues reported there but Lucky does answer and try to help users.
