General Mach Discussion / Re: M3 M4 M5

« on: May 27, 2006, 07:59:37 PM »

You should be able to do it with some VB and a user dro,  if you add a few lines to the M3, M4 & M5 macros.

In the M5 macro add something like this

Call SetUserDRO(Number, 0)
DoSpinStop()

In M3 put something like

dir=GetUserDRO(Number)
if dir = 0 then
  DoSpinCW()
  Call SetUserDRO(Number, 3)
else
  generate an error message and stop the machine
endif

In M4 put something like this

dir=GetUserDRO(Number)
if dir = 0 then
  DoSpinCCW()
  Call SetUserDRO(Number, 4)
else
  generate an error message and stop the machine
endif

Not sure it will work, as I have not tried it, maybe Brian will correct my errors.

G-Code, CAD, and CAM discussions / Re: U,W supported?

Like Fanuc , 22 Years, man and boy.

Do you think these features will be included in the future?

G-Code, CAD, and CAM discussions / U,W supported?

« on: May 24, 2006, 05:31:49 PM »

HI,

I think this if for Brian,

I have just run my very first program on my mini lathe.  This is the program (not long not elegant)

G18 G21 G00 G94 G40
G00 X47. Z1.
G01 X30.5 F30.
G00 X46. W.25
G01 Z-16.9
G00 Z1. U.25
X60. Z50.
M30

Mach3 Turn is ignoring the U and W commands.

This is my question :-

is W and U not supported or has it to be used in a special way or have I something set wrong?

For those out there that don't know what I am talking about a 'U' is an incremental X move and 'W' is an incremental Z move

Also is automatic chamfer and radius supported?

E.G.

G00 X20. Z0
G01 X30. K-.25 (auto chamfer)
Z-10.

or

G00 X20. Z0
G01 X30. C.25 (auto chamfer)
Z-10.

and

G00 X20. Z0
G01 X30. R-.25 (auto radius)
Z-10.

Thanks

Graham.

It sounds to me as if you loaded a turning file,  this would change some of your defaults.  Then a re boot would have put them back.

I use AlphaCAM and use a standard Fanuc series 6 post.

Never had any problems with it.

General Mach Discussion / Re: Initial set-up Mach 2 or 3

In answer to your question about the pin outs.

You only have a limited number of inputs and outputs on the parallel port so it all depends how many signels you require to drive all your components.

if you have 2 limit switches and a home switch on each axis all connected separately you would need 9 inputs and you only have 5, so its best to use the axis + limit as the home switch and link the 2 limits on the axis together, this way you only need 3 input pins.

All looks ok apart from the pulses per second looks a bit low, this will be shared between three axis so the max number of pulses per axis is about 4500, if you are going to use servos then they normally require about 6000 pulses each.

Go to www.artsoft.com and download the optimisation information and work through that, then run the tests again.
