Hi Happytriger, the normal application of a driver to the LPT-Port is known I think. But the UDX need an explicent step for CW and CCW rotation on a change from low to high at CW-pin the motor turn one step right and at a change at CCW-pin equal one step left. So you have to generate these - eq. Via the attached schematic: the step-signal is at the input of 4066 and will be switched through depending on the direction state. The resistors are pulldown - the logic is active high hope you understand:-) Greets Frank Pinouts: 4066 input - output - trigger 1 - 2 -13 4 - 3 - 5 8 - 9 - 6 11 - 10 - 12 7 GND 14 VCC 4009 in - out 3 - 2 5 - 4 7 - 6 9 - 10 11 - 12 14 - 15 1 VCC 8 GND. Thanks Frank, I will build 1 asap and test it. I did build a circuit for my driver, I used GD74LS04, is Hex Inverter. I used KCAM to run my machine, it seems there's a problem with the windows based software, when I jog the motors in Kcam, the motor turns but not very smooth and in Turbocnc in DOS the motor runs smoothly. What software are you using and does the motor turn fast, ie 2000rpm? ![]() Barefoot friends indo sub. I have a vexta controller which turns the stepper motor quite fast, but when connected to computer the speed has lower a lot, my task is to link to the computer, use a controller software and run the motors as fast as the vexta controller does. If you give me your email address I'll send you a movie clip of the motor running using vexta controller then you'll know what Im talking about. I attached a DXF file of my GD74LS04 circuit. Hi Happytriger, I know, that there a different drives availiable - but mine didn't support Step & Dir. You're inverting the signals, but if your driver need explicent clock for CW and CCW your schem didn't work. Then you have to split the clock fwd and rev.

Ballscrew pitch: 4mm driver: Gecko G210 stepper: Nanotec 5618C0408 (1,4Nm - 4 Amp parallel winding) 1/5 step mode (1000 steps/rev) - very smooth:-) PC: PIII 800MHz 256MB XP Pro Software: Mach2 best speed: 35000 Hz (max. 45000) until a few months ago I used TurboCNC on a 400MHz K6 (DOS) with max. Streming inajuma eleven go 1 sub indo. 40 kHz Whenever TCNC will support G41/42 I will sell Mach2 I would like to use halfstep, but there are some problems with the multiplierboard G901 of the geckos:-( the UDX I tested up to 1000rpm - but I stopped more tests because of missing tourque. Maybe in future another application (lathe) Greets Frank. I have an old Super Vexta 5 phase driver which I can't seem to locate in my junk pile of stuff. I think the part was udk5107. The opto inputs were CCW and CW but someone told me that there was a switch that made the unit into STEP/DIR. At first I couldn't locate the slide switch since it was covered with dust balls and dirt so I took it apart and cleaned it out. It was inside the case on the very edge of the board. Anyway once I moved the switch and connected it to the parallel port, it worked with turbocnc as a STEP/DIR driver. I don't know if your driver has this capability but can't hurt to take a look.
