Not sure if I can explain my thinking but I will give it a try…

1)   Your stepper motors should ‘lock’ when your complete system is connected and powered up.

2)   You have said:-  ‘What I can see are if I disconnect the parallel port from the computer the CNC says one "click" noise and then you cant move any axis by hand, if I connect the parallel port into the computer it make a "click" noise and then I can move all 3 axis by hand.’

3)   My opinion is that you need to find which (LPT) wire is disabling the machine and then set your Mach3 configuration so that particular wire is either ‘Active Hi’ or ‘Active Low’ so that your motors ‘lock’ when the machine is connected to your PC and powered up.

Hope this helps.

Sorry Norsk, I did not explain it well - my mistake. 

I was referring to changing the active states within Mach3 (Config / Ports & Pins).

Hi Sam,

Same thing happens here with both versions fd and efb of the plugin.

However, I have not determined if this is a USS issue or a Mach3 issue ?? (obviously one or the other is sending out the un-requested series of step pulses).

Sounds like you may have an ‘Enable’ signal after all.

Assuming that the pin assignments on your LPT cable are ‘standard printer port’ then with the machine connected to your PC and Mach3 running change the ‘active state’ (hi / low), one at a time (and click Apply / OK after every change), for each output (1-9,14,16,17) to determine which pin and what state (hi / low) causes your motors to ‘lock’.

Hi TL,

Looks like you have successfully identified the problem and come up with a possible solution all on your own. Good work my friend. 

I look forward to seeing some pictures posted of the things you make with your machine.

Mach3 under Vista / Re: Windows7 64bit -> Mach3 -> Smooth stepper -> Xylotex board v3.0 -> Machine ???

« on: May 28, 2013, 05:09:36 AM »

Can I just connect the parallel outputs from the Smooth Stepper to my Xylotex board ? ( i.e., Will the Smooth Stepper work as a simple USB to Parallel converter or should I have to do any interfacing circuit ?)

Hi Harish,

Yes, It is a straightforward connection and no additional interfacing should be required.
There is some setting-up to do in the SS config. but that is fully explained in their documentation. http://warp9td.com/index.php/documentation

Hi Sam,

Cast your mind back a while to when I was starting out with this project and having problems laser cutting acrylic with smooth edges.

Who was it that took the time to look at my GCode and discovered that my CAD/CAM created tool-paths were rubbish ?

Before your help. http://www.machsupport.com/forum/index.php?action=dlattach;topic=12444.0;attach=21730;image

After your advice. http://www.machsupport.com/forum/index.php?action=dlattach;topic=12444.0;attach=21738;image

You can’t tell me that you are having troubles with shoe laces.

Is there a check to turn the slave on?

I am not an expert at this because I have never had occasion to actually do it but…

In Motor Tuning make the settings exactly the same for both the Y and A axes and save the settings for each.
In General Config uncheck the A-Axis so it makes the A axis Linear.
In Slave Axis select Y to A then restart Mach3.

You should now have both these axes slaved.
