Easily done - glad it's sorted!

What logic levels do the stepper drives expect to see?  As it happens I recently upgraded my lathe to use that interface board and I found I needed to supply +12v to it for all the interfaces to work correctly.  I think the supply pin is one of those on the TB on the RHS of the PCB.  I assume the red wire to the 3rd from the right on the bottom is 5V?  Where is your 5v supply coming from given there is nothing plugged into the USB connector?

This is often because either the direction signal has come off the stepper drivers or the timing of the direction signal relative to step is wrong. Can you post some more information on your set up and some wiring photos?

VB and the development of wizards / Re: Wizards write question

Are you talking about the Mach3 engraving wizard?  I suggest you download F-Engrave and use that instead to generate g code.

Is the "m" case sensitive?

Put your F360 file in a .zip, as it isn't an allowed file type - .zip is.

What do you mean by "starting position"?  A good start would be to put the tool tip at the origin of the item you want to make if that's possible and zero the program coordinates.  Looking at the code it is quite complex for a "learning piece", maybe try something simpler?

One idea might be to try this: https://www.machsupport.com/forum/index.php?topic=45287.msg288673#msg288673 - which is a Python wizard to generate g-code for a knurl.  It would take F360 out of the equation, and I know it works.

M3 and M4 scripts are written in different languages and really only the program logic would carry across.  However there are many M3 scripts to do this sort if thing and thay would probably be a better starting point.

As long as you don't try to run concurrently no problem.  You just have 2 profiles one for lathe and one for mill.  I've done it for years.

Anything in brackets is interpreted as a comment butthe odd characters before (...New File Started) won't be recognised.  Try deleting them.

On the "open" dialog box select "all files" rather than .tap files - g-code files are only text files under a different name.
