General Mach Discussion / Mach3 Duplicating line 150 four times.

« on: July 11, 2012, 02:28:56 PM »

Hi,

I'm running into a problem where everything past line 150 of my gCode is being cut-off(not viewable in the mach gcode cycle view) however whatever is line 150 in my g-code seems to be duplicated four times in machs gcode window however it isn't in the actual .tap file

Anyone run into this before?

General Mach Discussion / Mach3 Threading

« on: July 11, 2012, 08:54:15 AM »

Hi,

I currently have setup my index input in Mach3's Ports & Pins. I have 1 pulse/rev from my spindle encoder and can view my accurate RPM in the spindle DRO on mach. My question is, do I need to configure anything else to do threading or am I all set? Is the index input all I have to set to enable this?

Thanks

In otherwords, how can I make a part of x and z inches appear in the toolpath display for me to practice MDI on?

Hey guys,

I'm new to Mach3Turn and I'm wondering how I can setup in the toolpath display, a simple rectangular work piece with a specific height and width. i.e .5" wide and 2.450" wide just so when I'm playing around with the MDI I can see a workpiece.

Thanks alot!

May I suggest you have a look at the LazyTurn Manual which can be found in Members Doc's.
In one of the reference section's there is a listing of many files posted which can be opened and run.
The above should give you manny clues as to how things can be done on the lathe.
Please walk before you run.....,

True enough Rich but can you please tell me if I am right when I say that doing a arc in one corner of the part in the toolpath of mach like so
would be the same as what I want to do here since the spindle is rotating and it is occuring at all points / sides

General Mach Discussion / What would this basic part look like? CNC XZ Lathe

Hey guys,

Very new to CNC and machining in fact. On a simple XZ plane lathe, could you please tell me what the outcome of this part would be. The grey background represents the part and the red(embarrassingly drawn in paint) represents the cut.


What Im lost on is what does the four arcs(yes those are arcs) at radius of .250 on all four courners do? What would this look like on a part?

My second question is, from what I understand on a XZ lathe what you do to one side of the part on a lathe you automatically do to all sides(because the part is constantly rotating.) Because of this, does one arc at one corner have to be programmed in and that is it and it would be the equivalent of the first picture I posted?


Thank you for your time!

G01 X 1.0 F1 - WOULD MOVE X 1 UNIT POSITIVE AT A FEEDRATE OF 1
G00 X1.0 - WOULD MOVE X 1 UNIT POSITIVE AT MAX RAPID RATE
G91 - IS USED TO SET  INCREMENTAL DISTANCE MODE
G90 - IS USED TO SET  ABSOLUTE DISTANCE MODE

Great thanks, answered my question!

General Mach Discussion / Move X first then Z

« on: July 02, 2012, 05:02:34 PM »

Is it possible in Mach on a command such as G01 or G00 to move to the desired X coord and then to the desired Z instead of moving both at the same time? Is there a setting that can be enabled/disabled or is it impossible?
