Title: setup speed ref in mm/sec
Post by: StefanV on October 26, 2012, 09:59:12 PM

In order to use the same code using Mach3 at home as the Multicam I use at work in metric, I need my speed settings to be interpreted as mm/sec, not mm/min as Mach does.
Now I need to go into the G-code and change every F setting to 60 times more to make this work.

Any suggestions on how to change the setup of Mach3 to go from mm/min to mm/sec?
Can I change some factor in the XML file to make this conversion automatic?

Thanks

That I am aware of there is NO way to do what you want. Mach3 only deals in MM/MIN or INCHES/MIN.

IF you needed to go the other way it would be a piece of cake  from mm/min to mm/sec  just redue the FRO to 1.666% and you would have it.

BUT mach cannot do over a 200% FRO .

Is there no factor in the XML file that influences this result  :( ? If not it may be a good idea for the next upgrade.  Or, let the FRO go to 6000% :)

This being said, is there a document that explains the settings in the XML file and possible modifications?

Thanks

OH you can modify the XML but it won't change anything as to how the core of MACH3 works.

I don't think you will see ANY major changes to MACH3, maybe for Mach4 in the future.

Can you not alter the CAM to output mm/min as default? Failing that why not enter the feed you enter in CAM as 60 times greater?

I have another machine that accepts mm/sec only in metric. This one runs production at work. Unfortunately there's no way I can change that setup. I was just hoping to use copies.
The last resort would be to write a procedure in basic that opens the g-code file, finds all the F-codes and multiplies the numbers that follow these by 60. This way I would end up with a second set of g-code files but it could work.

All machines I have come across are programmed in units per minute and it seems to be the industry standard way, but then again I only have experience of metal working machines maybe other types are different.
