Yes, in a sense.  It is actually more than just a USB to Parallel converter.  It is a true motion controller which means it is specific to CNC interfacing.  It also means that it "off-loads" much of the timing critical processing from the PC to this motion controller, freeing up CPU resources on the PC.

One thing of note: as you move into the newer Operating Systems such as WIN 8 or WIN 10, those operating systems put much more stringent limits to direct hardware access.  Mach3/4 will not be able to communicate directly with the Parallel Port and will need to have a motion controller of some sort (with a compatible plug-in) anyway so this may be something you'll want to do to "future-proof" your system.

But the short answer is that most of the Motion Controller adapters should work with your laptop.  I have the UC100 MC with plugs directly into the parallel port interface on my control box and connects to the PC through the USB port.  Works great.  Your mileage may vary with different MCs as the implementation is different from one manufacturer to another.  It is dependent on both the hardware they provide as well as the plug-in itself.

Hope that helps,

EDIT:  Here a link to the UC100:  http://cncdrive.com/UC100.html  You can also find them on Ebay, Amazon, etc.  Or you can click on the "Distributors" button on that page and find one you prefer.  I think I went with CNC4PC when I ordered mine.

Ok, I understand your point about additional programming for the functionality.  My point is that the logic of your programming shouldn't have to change as a result of changing from NO to NC if you configure Mach3 Ports and Pins to match accordingly.  Any additional programming would be for desired additional logic needed for functionality, not wiring configuration.

Moving forward, especially with the lack of parallel ports on newer PCs, I would suggest looking into getting a motion controller of some sort.  Since you already have a breakout board with a parallel port interface, I would suggest the UC100 as it has an excellent plug-in to work directly with Mach3.  I'm not sure about Mach4, though.

I would say yes, they should be the same.

Motor tuning, acceleration too slow.  My initial thoughts when reading your message was scaling active on one axis or another but in that picture it definitely looks like an acceleration setting issue... at least to my limited experience.

Again, I don't see a need to make major changes to the macro.  No matter if it's NO or NC, due to the configuration of ACTIVE LOW for NO or ACTIVE HIGH for NC the logic in the macro would be the same.  If <switch active> THEN <do something> or IF <switch inactive> THEN <do something different>.  You could also use IF <switch active> THEN <do something> ELSE <do something different>; or even IF <switch inactive> THEN <do something different> ELSE <do something>.

The bottom line is the wiring does not change your macro logic as long as you have the configuration set in Ports and Pins to handle it appropriately.

Agreed.  Peter has said it all.  Safety.

Now, as far as the Mach3 bug, are you writing a macro to check the status of the limit/homing switches?  No need to do IF NOT.  Just set the switch input to an active high when using normally closed switches (wired in series of course) and you're done.  The logic for macros is still the same, IF <limit switch state = TRUE> THEN STOP (or whatever action you need to do).  No need to do an IF NOT check.  You could also do an IF <limie switch state = FALSE> check if you need to make sure the switch is NOT active.

Hope this makes sense.

It sounds like your machine/Mach3 is set to default to MM (G21).  You can either change this manually on the "Settings" screen (do NOT use "Select Native Units" on the Config menu) in the lower right or more preferably, make sure your G-Code file has the appropriate G20 (inches) or G21 (MM) as standard practice.  This will ensure the correct sizes are used regardless of the default settings on your Mach3 setup.

Again, I can attest to this too.  I have a touch screen laptop that I am using and it works great.  Some of the controls on the screen may be a touch too small for my liking so I have to pay particular attention to exactly where I'm touching on the screen, but it works great.  I've also added an XTc HB04 wireless MPG to my system and that makes things even simpler to use.

General Mach Discussion / Re: Am I loosing Steps, and what should I do
« on: August 10, 2016, 04:45:13 PM »
Ok, yes.  Mine are the M542 and utilize only DC at up to 50V.  Yours are rated quite substantially and can use either AC or DC looking at that document.  So that eliminates this as a potential source of the issue.  Just something I saw and am glad you had the documentation for it.
