thanks and regards

will be 79USD for 7Apeak ( 5A RMS) /80V bipolar drive


b.r

could you give price list

thanks and regards

to Larken.
I was build bipolar drive 7A 80V two year ago.
10A 120V just finished last week

i thinks you can coding plugin for mach3, like SmoothStepper

new computer or laptop don't have lpt port

thanks Larken
Official price will be after I finish working with the aluminum cover producer.

bipolar controller cost will be high, because using MOSFET drive, and a lot more power FET
with...

Thanks Mrwild, sory about my english

Max motor voltage is power supply voltage. But it is unipolar stepper drive, Gecko is bipolar drive.

Products assembled in vietnam. Driver will ship from...

We producing heatsink for driver, i hope finish soon

the price will 39 to 42usd

thanks and regards

Thanks MrWild,
1. YES, no mid band resonance damping
2. RMS is 5A
3. Have microstep morphing

thanks and regards

hi Mariss, how about step servo project :)

can you help me find hardware use with robofac software?

thanks alot

great work

it cann't run on xp.

use can use mach3 controller to make cnc ploter

b.r

what is software control machine?

thanks

i have alpha step (vexta) it not like servo, it remember how many step lose and correct it.

to Mariss, did you have final protype stepper servo driver board

b.r

to Mariss
ls7290.pdf‎ this file is unipolar driver schematic
i thinks bipolar in develop

you can find motor here

b.r

if you use switching psu, you need add diode to protec PSU.

thank you for ur interest in our Belief driver
We are going to launch our first product in Febuary 2010

thanks and regards
