Hi, Jerome
My board works with signal ENABLE = 0.
Can You help me?
Configuration:
PC Toshiba Satellite Pro 4200 with W98 >:D<, but with LPT!
CNC SPARTIA by Papy Kilowatt (in progress)
board with Toshiba TA8435H.

With regards, ZbigPL

Hi,

I'm sorry, I don't understand your problem

My englisch is poor, so my sentences are shorter then ideas.
Jedicut send signal ENABLE =1 (pin 17). My drivers are activated by signal ENABLE = 0.
I had to install inverter (75LS05) at pin 17, but software solutions would be better.

What kind of CNC board do you have ?

Give me your e-mail adress, I'll send to you special dll you will try.

CNC board is self-made with Toshiba TA8435H drivers.
With inverter motor works.

With inverter, motor works. But what dll do you use ?

Bonjour!
CncNet98 and VisualCNC

Hi !

You have an e-mail

Merci beaucoup, Jerome!
Both dlls work perfect without inverter.

Hi!
Once more - configuration:
Windows 98 SE
Board (without timer) input signals (TTL):
ENABLE - active Low
CLK (min 1 µs)
DIR

Using CncNet98.dll or VisualCNC.dll rotational speed is constant and low (about 2,5 turns/10sec) independent on "Speed". I can control direction of rotation.

MaxCom.dll do not work (Win98?).

With MaxCom_XP.dll(?!) I can control the rotational speed ("Speed">80000) but motor not react on signal DIR.
Manualy conecting line DIR to 0V or 5V changes direction.
Voltage levels (0,24V/4,24V) on line DIR are identical with CncNet98.dll and MaxCom_XP.dll.
Do you have some solutions?
