Hello everyone,
Does anyone use Vexta Drivers to control their CNC machine?
I have 3 Vexta driver UDX5114, and I would like to know how to wire them to the parallel port and Im using the trial version of KCAM to test them...
Thanks

If you mean drivers 3 vextra motors you dont can connect motor to pc port traight. You need mainboard=drivercard to motors. good cheap board is "3d step.de" sites in web. and meny other L298 and L297 board. or pic,avr mikrokontroller driver or 3977 etc,etc,
my picture site have some pics 3d-step card(scanned when card gome home)

Thanks for your information masaV, I really need it...
You know that's what I did, I used pin2 = step and pin3 = direction hooked to +cw and +ccw respectively, and short circuit the -cw and -ccw to ground, well it turnned out not very smooth when running and Im looking for information to solve this problem,
Is there any schematic of the driver board/card??,
