Have you made the suggested registry changes ?   http://www.machsupport.com/forum/index.php/topic,2385.0.html

Pleased to hear the LPT cable is OK - that's another possibility ruled out.
I don't know exactly what you attached (WinRar ?) but it was not your .xml file. The file is in your Mach3 folder named <your profile> .xml  - could you perhaps try again ?

This problem has to be something so simple (and basic) that it is staring us in the face.

Have you tested the LPT cable with a multimeter (that pin1 is connected to pin 1, pin 2 to pin 2 and so on) ?

Can you attach your <your profile> .xml file (from your Mach3 folder). You need to copy the file then rename the copy to captainleeward.xml before attaching.

Steppers look OK so it's back to the drawing board.

You are making progress.

Try selecting Step Low Active for your X axis (Motor Outputs) and see if that makes a difference.

Also measure the voltage on your Parallel Port X axis Direction pin (between pin 3 and pin 25) it should change between approx. 0 volts when jogging in one direction and 5 volts when jogging in the other direction. If it only changes between approx. 0 volts and 3.3 volts then that may be the issue.

That would be very useful indeed but I have never heard of any method of importing a Vectric tool table into Mach3.

I think you have to do it the hard way

Hi John,

By trying Fusion 360 doing the tool comp. and the same error persisting has, I think, shown that it is not a Mach3 error.

From the information you have given I would suspect the problem is a mechanical issue with your machine, perhaps backlash, a loose set screw, etc.

Your wiring should be something like this, with the addition of 5Volts supply to the BoB (not sure about using a BEC as I have never tried that).

I never use tool radius compensation within Mach3 (it's easier for me to let the CAD/CAM software take care of this) so my knowledge is limited.


First, check that you have your tool table set up correctly then try running your code again but first change the G40.1 to G40
Does this produce better roundness and dimension ?
