Hi Art,

There is still something wrong. If I compile the program then run

then VB bombs with a protection fault.

There are also some major redrawing problems when using the OCX

from VB.

Labels don't get redrawn correctly if the main window is resized

or

another window is dragged over it. Also when you switch from one

page to

another the controls on the new page don't always get drawn and

the

controls from the previous pages don't get erased. Forcing a

refresh by

moving another window over the application sorts it out apart from

the

labels.

With Borland C++ builder the IDE doesn't crash but I get the same

redraw

problems. I also had to use SetWindowHandle to stop everythig

getting

drawn on the desktop. Also for some reason I get an access

violation

when I try to call SetProfileName()

I thought it was my poor vb understanding but i am getting all the
faults above of which the first one (vb crashing when in ide is a
pain).
I have been writing progs and having to compile to exe to check them
which does not make debugging very easy.I also can not get the about
box to display the license,it displays "demo mode" even though
everything is in the same directory (license.dat,Project,ocx).

At least i know i am not going mad.

Your best bet is take the original part and measure it and draw it on
a simple CAD or illustration program. The issue is not ususally
duplicating a flat part although you have to cut it flat. Another
issue is how you lay it out on your material to cut it. You seldom
have something where just one fits on standard stock or even if you
do you won't have the right sized stock in house. (#26 in the LAw of
OBJECTS) Probing is best used for complex 3D objects that are more
difficult to measure and draw. If you are concerned about precision
and accuracy then plasma is the wrong tool to use. You could
probably lay the original piece down on a piece of paper and trace
the outline with a pen. Scan the tracing and do an auto trace using
one of the cheap or free packages available. You can get a cut path
pretty fast. Plasma is like carving wood with a chain saw, it cuts
fast but fine detail is a little hard to produce. I cut a series of
brackets for a guy. He brought me a sample and I measured it, drew
it in QuickCAD (10 minutes), imported it into the CAM and spent more
time figuring out how to get 48 pieces on each 2 X 2 sheet than it
did to draw it. Actual cutting time was less than a hour for 4
sheets.

If you can use something like CorelDraw (Vector drawing and
illustration package) simple shapes using squares, arcs, circles and
lines are quick and easy. Export in DXF or HPGL and import into
MACH2 and select the right import options, and you have a cut file
that will run your machine. Anything you can cut on a plasma table
you can draw in Corel in less time than it would take to setup and
probe it.

Just 2 cents from a guy that spends his time snorting black smoke and
metallic dust and dodging showers of sparks.

It doesn't sound like you have Estop problems anymore so how about changing the subject line to "I got more toys than you do" so I can delete it before I waste time opening it.

Do you mean parts you will be making with the plasma cutter? I.e.
someone brings in a sample and says 'make me 10 of these, but I don't
have a drawing"? If so, sounds like you need a touch probe. One of
these maybe:


found it using Google for [cnc "touch probe"]. I've seen others too.

Hi all,

Especially Art, you can get one of these I'm sure. My friendly X-Ray
repair guy brought me more treasures yesterday. In the pile of stuff
was another vertical tube stand with the collomator head still in
place. If you look at my photo album, you will see this is ready
made for the 4th and 5th axis operation for a large scale router.
Pivots right and left(all tapered roller bearings) as well as
10degrees negative rotation of the cutting plane and +90 in the other
direction. Even has a ready made base for mounting a trim router.

The back side of the curved moving surface has a curved rack type
gear already mounted.

Make friends with a Medical repair company guys. There are treasures
to be had.

What a sick group we are.

Gavin,

I have recently purchased a new ShopBot and have not cut anything
with it yet. As soon as I installed the software it became apparent
that the thing to do is replace it with Mach2, same as on my home
built router. After speaking with Marris Freimanis and Ted Hall
about this issue, it seems that the simplest solution is to replace
the control box with one using Gecko drives.

There may be a market for the ShopBot control box with people
upgrading older ShopBots.

CNC Plasma Cutter

I know this is slightly off topic, but I was hoping there might be some
experts here.

I am creating a toolpath in Mastercam and have the clearance value on my
Contour set at 2".
However, when I post the output (using the Mach2 post processer as well as
others) it starts at Z=0 and goes straight to the XY position of the start
of the contour before going to Z of 2".

Does anybody have any ideas to what I'm doing wrong?

Thanks,
-Chris

If you write an VB application with a button on it that calls StraightFeed
( 10,10,10,0,0,0) in it does it move? If not, send me the application, I can
debug such a thing quite easily and see what the holdup is. Send the
directorty you use zipped up so the VB application, the .xml file your using
are both in a directory. I'll let you know why theres no movement...

You cannot run Mach2 at the same time as your VB application. When you
use an OCX, you must have exclusive use of it.
Send me an offline message so I can send you a small VB application which
uses the OCX, I don't have the source, but it shows the VB interface works.
Unfortunatley, I don't use VB at all, only C++, but the ocx shouldn't crash
on you in any event, I suspect it may be the SetWindowHandle() routine must
be called to set the right interface to your form...

Peter,

I was able to get the Master5 ocx to work by naming the OCX instead of:

Private Motion As Master5Remote

So much for reading books!

Thanks for the help! I'll work with the Master5 OCX for now.

James

Peter,

Thanks for the post - I think my first mistake was trying to use Master5
OCX.

I downloaded the demo for Mach 2 Rev 4.0 lockdown to try it out. I created
a new form in VB5 and followed your procedure below. I copied the text into
VB5 - when I try to run it, VB5 crashes. I've tried it with Mach2 running
and not running and have been getting mixed results.

When I am able to have it run without crashing, I get no message boxes which
tells me something is wrong.

I am able to run the OCX driver test successfully and get around 24K pulses.

I haven't yet registered Mach2 as I just downloaded it and wanted to make
sure I could do what I wanted before I send Art his well deserved money.
Could this be the problem?

Basically what I want to do is be able to write my own VB code and utilize
Art's routines to control the motor and "see" the position through the DRO.
I don't think it's out of the question, I just can't get the right format
down for getting started.

Can I do this with an independent VB5 program or do I need to do it with
scripting inside Mach2? That will help me make some decisions.

What I'd like to do is create a little doc that shows any other idiots like
myself who are interested in getting started exactly how to do it. I want
kid's instructions - not expert's jargon (like all of the VB books out
there - "first, create an instance of the class so you can initialize the
object as private") to be available to everyone who wants to get into this.
I'm willing to take a stab at the docs (which would greatly pale in
comparison to John Prentice's work) but if I can't get started, I certainly
can't tell others how to do it.

Any help is appreciated.

Thanks,

James
