hi, i'm a mechanical student n doin final year project.
due to the lack of electronic background, my supervisor allow me to ask ppl 2 build or buy the electronic circuit.

my project is an x,y,z axis linear movement pick n place.
i will be using stepper motor n i need a driver to control it.
may i noe izzit jalan pasar got ppl help me build n design circuit board for me?
or other eletronic expert willing to help me?

tq

sry for not putting the clear description about my project.
i really stupid come 2 electronic, that'y i choose mechanical XD

yah, i copied the concept of CNC into my project. i wanted 2 buy the driver, but most of them is oversea so the price will be expensive. Since most of them is applicable for powerful stepper motor. Mine is little project only.
my supervisor advised us that the best will be order within malaysia or ask expert 2 help wor.

tgrr:
i heard from my friends that some shop in jalan pasar got help ppl 2 build circuit after noted down our needs. We just explained wat we want n them will settle the board for us. We just need 2 pay only.
My budget for driver depends on all in 1 or modular lo. The best not exceed rm300-400.
for ur info, i will controlling using vb.net by sending pwm signal.
since vb.net got more simple language n interfacing (GUI) for newbie like me 2 use. The motor will be >5v (cytron) depending on budget also.

i founded a website http://pminmo.com/ that got free source circuit. Now i wondering either Tachus42 3 Aixs Board (all in 1) suitable for me?

tq for the help.

i will consider mainly unipolar stepper motor since many people say it more easy 2 control. In other hand, i noe bipolar got better holding torque which is important for my z-axis (a bit heavy).

from my research, I need 2 use PWM signal rather that input signal from parallel port becoz i need 2 hold some position like (z-axis) when picking items. If use input signal from parallel port, izzit it only for on n off mechanism? it will slide down, i guesss.
correct me if i'm wrong.

hope 2 heard ur advice again.

tq for all the info.
then i try seek help aurora since he is more nearer.
