General Mach Discussion / Re: Mach3 Spindle output variation

Pin 1 is often not used when it comes to parallel port operation (it is bit of an oddball).

Can you perhaps use a different pin (2 - 9, 14, 16, 17) ?

General Mach Discussion / Re: Mach3 Demo Not running as expected

Might you point me to a sample mill  G code file that will run properly on a freshly installed copy of the Mach3 Demo software;  using the default mill profile ? I understand machine coords, work coords etc.

There are many here to choose from; http://www.machsupport.com/forum/index.php/topic,18345.0.html

Excellent.
I am pleased you found a perfect solution.

Just a note for others - when fitting a PCI Parallel Port card to a new PC make sure the card is to the old 5Volt standard and not the new 3.3Volt standard. If your controller is expecting 5Volt TTL logic and only gets 3.3Volt TTL logic then loosing steps is often the result.

General Mach Discussion / Re: Mach3 on USB card Windows 7 help please

Tweakie,
I would rather use Mach3, I have ran it since I started carving.

Unfortunately, that's not a Mach3 compatible board.

One of the questions would be, which should I go with, Mach3, or Planet CNC on getting my machine back running?

Obviously I am biased but I would recommend Mach3 or 4.

So really want to try making the USB board work if at all possible. I have no paper work at all, so any help with this would be so kind.

Perhaps if you provide full details and a picture of your USB breakout board someone may be able to help.

Could be that you are still using your original Screen.set

In the Menu  View / Load Screens select 1024.set for the standard screen.

General Mach Discussion / Re: Switch to Another Work Offset When the G-Code is Loaded in Mach3

« on: November 30, 2017, 09:21:52 AM »

Why would M30 change the offset?

Probably a question for Brian.

Try it and see...

As the Gcode loads and is read DRO(46) changes to the current offset then when the M30 is detected it reverts back to G54 - it will change to the current offset as soon as the Gcode is run (as discovered by Kvid).

But, as said, I am not certain this applies to all versions of Mach3.

When I load G-Code DRO(46) contains G54 until I click Cycle Start and then Mach3 sets it to whatever work offset is in that G-Code. I run Auto Tool Zero script before I click Cycle Start.

It probably depends on which version of Mach3 you are running, however...

If your Gcode finishes with an M30 then the Offset and DRO(46) will be reset to G54 after the Gcode has been loaded (as you have discovered). Deleting the M30 from the Gcode will allow the DRO(46) to display the correct Gcode Offset for that particular file.

GetOEMDRO(46) returs number of the fixture that is currently active. I am not sure how is that helpful.

Modify your Auto Tool script to read DRO(46).

Once you have loaded your Gcode file DRO(46) will contain your Fixture number as defined in the Gcode file.

You can also read your current Tool Offsets from the other DRO’s

How you deal with that information within your Auto Tool script will depend on what you wish to achieve.
