I dsecided to try engraving some text using my milling machine.

I know that the DXF output from AutoCAD won't work for text, so
i "plotted to a file" which made a .plt file.

I am trying to import this file into Maach2 4.0 on my Pentium iV
2.6GHz Compaq Presario, and it is sitting there with the disk
churning for 20 minutes now!

Is this normal for the inout filktering/importing/whatever process?

Or did i do something wrong?

The file size of the .plt file is only 115KB.

Ross:

1) Try this in exact stop mode, does it still do it??
2) Try this in Plasma CV mode, how about now??

Yes, It is still in radians, I can't change that because its a windows
scripting function. I do intend though to put the code you sent into the
main OCX code base and select Constant Volume as a G-Code switch. Hopefully
very soon....

Maybe you'd better send me the whole program. I can't reproduce this one
and it sounds like a nasty one ...

Hey don't take the piss, not only me confused by Art's Canuk explanation
;)

The latest is, I think, one of the holes/slots should be half as big
again as the others, but twice as big maybe better.

I'm gonna do 3 slots at 2mm and one at 3mm - if it gets confused I'll
increase the 3mm slot to 4mm. Easy to remove metal, not as easy to add
it back again <G>.

One thing to bear in mind is the reaction time of some opto sensors. The
ones I'm using are good to about 10K rpm at the radius they are placed
from the spindle centre line and the gaps/number of slots, fine in my
application, but something to consider.

on M30 file rewinds and tries to go to X-10.7

Z-1.092 and stuffs the tool into the job!!

It tried to MOVE after the M30? M30 shouldn't cause any movement, if the
offsets remove, then the DRO's should simply read the non-offet position. Do
you mean that if you do a GotO zero's it moves into the stock, or do you
mean it actually moves from the M30????

It actually moves after the M30!

Here's the last few lines of the GCode

N2660 X25.9 Z22.3
N2670 G0 X30. Z40.
N2680 M05 M30

It moves to X30 Z40 then the spindle stops then it moves to X-10.7
Z-1.092!!

Summat really weird here :(

Art,
From reading the last couple of weeks posts, I think that the
problem with the constant volume macro that I sent you off list is
that the angular functions were in radians for previous versions. Is
that still the case with release 4.0? Have you had a chance to try
running that macro?
The only way that I am able to write a new macro is to load an
existing macro, delete its contents, write the new macro and save it
with a different name. Is it possible to use the Mach 2 editor to
write and save new macros?
Don

Try turning off the screen saver.

Hi,
I am having the same problem with 4.0. I went through the same

checks

and balances you did with the same conditions, with the pulse at
25000 for a short period of time until dropping to about 4500

pluses.

IM running XP professional on a Dell lap top. I don't know if this
makes a difference from XP home addition.

Best regards,

from the configuration pages select 'exact stop' mode instead of 'constant

If your accelerations are too low you will not be able to do very small
radius arcs at great speed anyway .. you may have to reduce your feedrates
for the very tight radius arcs if you want them to be follwed exactly and
your acclerations are very low ...

Art...

I cranked the acceleration all the way up and the problem virtually
went away, but I can't run the machine like that.

What's happening is that I offset my drawing by .125 to compensate
for the tool diameter, which means that the toolpath radius in the
bottom of the slots is only .125. Mach2 seems to be trying to do
some blending instead of following the toolpath exactly.

Thanks...Ross

Hi Art...

I just uploaded a photo of a problem I've been chasing today. Could
you take a look at it and tell me if you've seen this before? I am
cutting a 3/8 slot with a 1/4" bit. The slot width is perfect, but
the radius in the bottom of the slot is not right. It should be a
3/16" radius. You'll see what I mean in the picture.

Other arcs seem to be cutting fine. This part is a 5" circle with 3
slots cut in it 90 degrees from each other. The 5" circle is
perfect. Do I have an acceleration problem?

Thanks...Ross

Hi Christer:

Mach2's HPGL is very simply. It was meant as a simple import filter for
non-cam users. I never added Pen capability.
I will add it to the list. I have recently changed HPGL for version 4.0 so
that it has a "As-Drawn" as well as metric/english
selections as well.

Thanks,

Dale:

Latest locked version is still 2.0. The next one will be 4.0 if all works
out. The 3.5's were a functional test of 4.0's changes. All 3.5's have been
removed and expunged...

Hi Art

Just wondering if you gave any more thought to the Accel/Vel dro
thing we spoke about.I just thought maybe if you are stuck in all
that snow you might get round to a few older requests.I am in the
process of totally rewiring the router after much advice from
yourself,Robin,Marris.
But i will be up to tuning again in the next couple of days.Just
thought it would be nice to drink that cold beer you keep mentioning
and watching my stepper system AUTO TUNE.
Macro is just about ready just waiting of dro's.Hoping this will
also give an output to disk maybe of the steppers/driver strongest
points.
I am just hopin it will tune the motors without me standing over it.
I am using the ref switches to check the accuracy of tests involved
but on my system they are within about .01mm accuracy.Not bad for
mechanical switches!!!.

Regards
Mark

Hi Art
I am using Mach1 demo for now.
Is there a setting for that.
Can that be done in motor tuning?
Can't seem to find it.
Thanks
