VB books

Greg Nuspel

I was wondering what are good books on VB? I'd like to get a handle on this
but I have never done any object oriented programming, a long time ago I did
do 'basic' programs.

Re: Help on offsets and such

Just out of curiousity..What kind of switches do you guys use for limits or
reference switches?  Is there a link somewhere to help me wire them up?  And
how can I reference 2 separate motors that I have on the y axis?

Thanks,

Matt

Subject: RE: [mach1mach2cnc] Help on offsets and such

Just setup the ref switches machine coordinates positions in the settings
screen, after this you will only need to create an entry in the fixture
table, with the offset you have between the 0,0,0 machine and the machine
fixture origine.

Your Z ref switch is not a ref switch. If you use it as a ref switch you
will have to re-reference the Z axis each time you mout a new part, so your
absolute machine coordinate system for the Z axis will change each time, and
you will loose the software limits functionalities, because they relie on
absolute machine coordinates. You will loose too the possibility to use
program ranges values for Z (to check for program - machine compatibility) ,
because you will never know where you are physically on the Z machine axis.
More i think mach2 has not been fully tested in the mode you want to use it
and there are perhaps other drawbacks, like they are if we switch from mm to
inch for example.

It's better to have a true Z axis homing, and to use your "touch" probe on
the digitize input for zeroing the Z axis through the fixture or better
tools table where you can enter the tool diameter too for compensation. Next
you will have one more offset system (G92) if you do manual work on the
part.

You can do your reference program through a macro, see in screen designer
how Art did this on the 1024.set screens. But your first goto Z safe has no
sense because before the referencing the absolute machine Z = 0 coordinate
can be anywhere. (except if you use perhaps the persistent DRO
functionality). If you have a ref switch on Z, you will always go in the
right direction because mach2 know if you are at left or at right of the
switche (you have to use a half axis lenght ramp).

It should be in your case :

Code ("G53 Z"your Z safe position" ")
Do Button ( 22 )
Do Button ( 23 )
Do Button ( 24 )
Code ("G53 Z"your Z safe position" ")

But normaly we reference Z first, we go to Z safe, and next we reference
other axis.

Best Regards,

Olivier.

  Objet : [mach1mach2cnc] Help on offsets and such

  I got around to installing referencing home switches tonight.  I've been
eyeballing things on my router table, but with the switches I should be able
to be a bit more accurate.

  here is my question:

  1. I have a fixture on my table that has a 0,0,0 location on it and all of
my files are coded to start from this point. My switches are -2, -1.5, +.55
from the fixture 0,0,0.  I don't use any length offsets on my tools cause I
have my z reference switch set up as a touch switch (the tool comes down and
presses the switch when I reference the z).   What is the best way to
reference the anises and then have them know where to go using the fixture
0,0,0.

  2.  How do I reference all three axises in order.  I need to do the
following
              1. go to safe z
              2. reference x
              3. reference y
              4. reference z
              5 go to safe z

  Any help would be great!

probably not time well spent.

What is need is a full and comprehensive list of the Mach2 specific 
functions, their typical use etc.  A full explanation of how each macro runs 
in its own thread and what will happen if you call one macro from another etc.

because the macros and the VB attachaed to buttons is mostly identical, this 
can all be grouped together in one place to pull things nicely together.

pull all the screen designer stuff into this document too, add in some handy 
tips, hints, sample files, etc and its a useful programming/customisation 
resource.

Bill GriffinBill:

If you have not found the latest version of the Mach2Mill manual (in 
the files section of this Group) then it might be worth checking for 
information on Macros and Scripts attached to screen buttons.

If you HAVE found it, and it does not give you the information you 
need in the way you need it, then I would greatly appreciate 
pointers to what should be there (when you have discovered it some 
other way). We are currently considering how best to document 
Mach2's capabilities in this rather open-ended area.

I am sure you will find the Mach2 script features powerful enough to 
control the sort of things you decribe. There are some interesting 
applications posted on the Group (e.g. conversational machining 
screen). An I/O board should be fine for interfacing the "specials" 
but not, I suspect, main axis movements, limits etc. The Keyboard 
Emulator architecture seems to work well for non-time-critial input 
signals.

axis referencing

#6923

Is it possible to reference the Z axis, and next X,Y and eventually A 
and B at the same time ?

I'm using the ref all button actually, but the 3 axis ref at the same 
time, not very safe for the spindle, and if i have no rotary table on 
the miller i have to press the escape key after the first 3 axis are 
referenced.

If i use a macro with Dobutton 24 , 23 , 22, i loose some time 
because X and Y are referenced one after the other.


Thanks for your help,

Olivier.

  If that didn't help I think we have to look at what else can cause it. Can
you send me your Mach2Mill.xml file and the G-Code file so I can run a few
tests...Heres another clue...I have two G-Code files.  One generated by 
Vector which defines arcs using IJ.  The other is generated by 
Artcam which seems to define arcs only by XY coordinate points.

Nothing I do makes any difference in the Vector file.  Using the 
Arcam file in Plasma mode does fix the blending issue, but it cuts 
the feed speed in the arcs by 2/3, which burns bits.

The artcam file in regular CV mode blends the corners the same as 
the Vector file.

I'll send you both files, but I'll probably use the Artcam file.
