What is the make and model of your controller ?

Hello, I'm new in mach3.

I've install a windows vista 32 bits in a HP slimline s3020la also I've installed a manhattan parallel PCI card (158220) and run the mach3 vista registry patch.

The parallel port address is ok because I´ve check the 0 and 5 volts of the direction output signal and it's ok, I don't have a oscilloscope to check the pulse signal.

Also I instaled Windows 7 32 bits and check everything but the result is the same. I don't know how to check te pulse signal or how know if is sending the signal to the output.

Regards!!!

If the Direction signals are being sent OK then the Step (Pulse) signals will be OK also.

Check that you have the correct (for your controller) Step and Direction Pin numbers (and that the correct Port #) enabled in Config. / Ports and Pins / Motor Outputs.
Does your controller require an Enable signal ?

I am pleased to hear that you have it sorted.
Maybe good to set the debounce at around 200 for normal operation.

I think you should fit a common (star) Earth tag at the controller end. This tag would then be securely connected to Earth. All shielded cables would have their shield connected to this tag (the shield at the other end of each cable insulated and left unconnected). Your home switches should use shielded cable and your estop should use shielded cable.
Treat Earth and GND as two separate circuits.

Some while back I did a short write-up (mainly for beginners) which may be of interest. http://openbuilds.com/threads/electronics-101.693/

Just a suggestion…

You should regard increasing the Debounce as a sticky plaster rather than a cure and you really need to address the cause of the problem which, from what you say, could well be electrical noise.
As a first step, check that your limit/home switches (and Estop) use good quality shielded cable, with the shield connected to a ‘single point Earth’ at the controller end only.

Hi Kevin,

The Settings screen (Alt-6) has an axis calibration feature (set Steps per Unit).

Do you have access to your old PC hard drive?, if so then the <your profile> .xml file (in the old Mach3 folder) will contain all your previous Mach3 settings. If you copy that .xml file to the Mach3 folder of your new PC then you should be good to go.

Which axis is it that is doing the shaking ?
Is it the one with the slaved motors ?

On the Settings page check that the A Axis is not Inhibited.

Go into Config. / Ports and Pins then change the Dir. LowActive state for the Z axis.
