Hi everyone,
I was just wondering if it were possible to increase the output of the ucn5804b by using a low resistance pull up resistor to increase the ampage in order to run larger motors?
At the moment what is the largest motor oz/in the chip can run?
Thanks
Ryan
Hi MP,
SUCCESS!!! finally got the board working correctly, i found out that the wires from the stepper motor were round the wrong way, i am only running one stepper at the moment!
Thanks for everyones help!

Thanks guys for the help but i am still having a problem, i am using the half step mode, the motor only works at a certain speed, it also has direction clockwise but counter clockwise just vibrates or jumps counter clockwise. im using
12V 1A power supply
unipolar stepper motor:
200 steps per...
Hi guys
the s/w im using is TurboCNC & JalaCNC, i also tried changing the states i.e. one phase, step inhibit, half step etc, for some reason it doesnt like it, stalls or vibrates.
p.s
do you know if you hav 2 change the step to phase in TurboCNC?

Hi all, dont know if people still post to this but i need help. I have built the board, tested it and connected it, when in operation the motor is either 1 of 3 things:
1: Jumpy and just vibrates
2: Has direction but very slow and not much torque
3: stationary but with strong holding torque...
