Hello All

I need some help I looked in all the old post and couldn't seem to
find the OEM numbers for ABS DRO's. I think this was put into Mach2
some time ago... John I did look in the DN and the manual ;o)

Thank you for your help

Sorry I found it

5) Absolute DRO's are availbel. These show the machine coordinates.
There
are none on the default screens. They are DRO's numbered from 83-88
and it is in th DN ....

My bad
It was labled as machine coords and I think I had brain fade ;o)

John,

I have been waiting to print out the Mach2 manual until there little or no
changes. I have seen very little correspondence re the manual lately. do
you feel it is in a 'lockdown' state presently?

I added it and released it...see next letter...

Greg:

I was wondering if you think the system will run better on the G2002 than

off the parallel port?

In short, yes. The 6 axis pulsing engine is asyncronous and separate and
runs to 4 million pulses per second.. This makes things VERY smooth. I
haven't actually seen motors move this fast before, any stepper I've used
will lock up far before the current G2002 speeds I'm getting.
Mach2 version 4.0 can drive a Gecko in CNC movement and jogging, it just
doesn't do IO, it simulates IO as a test function. I need to finish a few
things on it. It does reduce the burden of the CPU and any laptop and such
can run it I think. I suspect even Win98 can run it, but haven't tried that
yet...

Marris has agreed to sell the 2002's for $350.00 dollars each at this point,
and its quite possible that if you ask him nicely ( He's a nice guy and like
most nice guys is a sucker for being asked nicely...) he'd put a copy of the
current Mach2 firmware in it before sending one out. That would allow you to
reburn the firmware as it gets completely finished since the Mach2 firmware
is flash upgradable through the USB port. So, if you don't need ref'ing
functions, turn functions or spindle control , the G2002 seems to be quite
usable for milling right now...

If anyone gets brave and decides to get a g2002, just let me know and I
can send a xml file which turns it on and the current firmware flash you'd
need. The more that actually own one, the higher the pressure to complete
the IO section which is only a couple hours work I need to get to. On the
same vein, anyone risking their 350.00 has to remember it is all R&D, this
is one of my problems, its easy to develop with 1000 of you using printer
ports who can bitch at me daily, but with only 2 people with Mach2 g2002's,
its quite a bit more difficult. While mine works fine, unknowns exist by the
multitude until more people are trying it out. I get feeling guilty spending
too much time on it and have to make sure the mill people have top prioity
on my time , then Plasma, then turn. The g2002 sits just under those 3
priorities. (Then there's my own mill, my life, my wife, .. ;) ..etc
..course my REAL job fits in there someplace as well...)

All that having been said, the G2003 will be fully functional within two
months if I have anything to say about it, even if its only for myself, just
because its a very nice contraption and its movement impresses me so much..

Thanks,

I have several cables that are pinned the same if you look at the
ends side by side and the cable that is required is 1 to 1, 2 to 2
etc. and matches up if the ends are opposed (mirror imaged). I
thought maybe it had a name (Laplink,null modem, etc.). No big
deal, I had to give mine away with some other equipment that I sold
so now I've got to replace it. If I can't find one I'll get in touch.

Thanks

Bill

Bill,

It is a standard cable. They come is several different lengths.

Look for one that has all 25 wires. If you have a problem finding

one, I

can send you one.

You can buy one but it is not serial . Make sure it is wired pin for pin
all pins used.

Can I get this in a book format? I hate reading online documents, just old

Super !

Merci Art.

Greg, vb script is only "objet oriented" since last versions, (v5 i think).

For most of the macros in mach2 i don't think you will need the power of
objects. And even for more complexe software, as you know perhaps, only 20 %
of the programmers are really using user created objects for industrial
control softwares.

You will not use neither the evenement system of Visual Basic because the
macros in mach2 cannot directly interact with the surrouding screen
interface objects.

If you did basic programming, you should be able to do vbscript programming
just learning what is a procedure and a function in vbscript, and perhaps
dealing with a couple of syntaxic differences, and the variant automatic
type for data (no hassel with data type in vbscript, until you have a
problem).

Give an eye here in the getting started manual :


ml/vtoriVBScript.asp



I think you will be ok in less than one or to day of vbscript programming.
You can give an eye to a moderately complexe macro i wrote in the file
section, if you want an idea and some examples of what we can do inside
mach2. it's Olivier Screen Folder. You will find an "interactive" screen in
it with some advanced macros. you can see them with screen designer. they
are located inside the "lancement" button of each macro.

For information i tried the free microsoft vb script debugger, but it
doesn't work with mach2 because the container object of the script is not a
traditional html internet explorer page.

Art,

I was wondering if you think the system will run better on the G2002 than
off the parallel port? I'm not fully aware of all the potentials of the
G2002 so I'm not sure if it would relieve the computer of some of it's
processing tasks.

Paolo:

Still on hold until I finish the IO. Hopefully very soon...

Next version will have a macro which can home any combination....

Mike:

Is there a good way to round my g-code files to the nearest .005. I'm not

sure, but I think that I lose steps because my setup only gives me 200 steps
per inch. If I am trying to control are 4 decimal places, the .000x steps
have to add up.


Nope. The .000x's do not add up. They are accounted for by Mach2 and will
not cause a lost position or step. These are continously added up till they
equal a step and then the step is put out.

Monte:

checks the specs on the 990MB on rutex.com. It shows how to put the
drivers in SPI (Serial Periferal Interface) mode so programs can speak to
it..

You don't need the motherboard, but you have to jumper a pin and put a 100
ohm on another...

Hi Markus:
Set your hotkeys for the movements and simply jog using the keyboard. Or
you can use the MDI line to enter comands for movement...

<What is need is a full and comprehensive list of the Mach2 specific
functions, their typical use etc.>

Yes sure, but almost all VBscript books are HTML oriented, and they suppose
the programmer has a basic knowledge of Visual Basic, that is not the case
for 97 % of the mach2 users...


But perhaps someone could direct us to a good and simple book for vbscript
real beginners. Personnaly i would prefer to have a simple introduction in
the John's nice manual, and found the specific informations on the Microsoft
site or a dedicated book.

For example on the 2 books i have on VB script i had no informations on the
file access run time.

Olivier.
