Jerry:

I do intend to handle this with a Taper Wizard. I am preparing the code for
easy use and addition of Wizards to do these types of tasks. For the Taper,
an Angle or Taper number will be entered and the code will generate to do
that compound movement.
I think the Jog keys and compass would be too coarse a regulation to
control it accurately, it really needs an angular input to be accurate. (I
think...)

Thanks

I see from my rapidly overflowing mailbox that some of you have an email
virus. I have letters from several with "Approved" or "You details
attached.".

I suspect a bad new virus is on the warpath....

Good idea a "virtual compound rest" to work with a jog button....You would need to type in line like: G0 Z4.0 X.5 then there should be a code for jog...if you don't want it executed. (if the taper is 4.0 long and the difference in the taper is .5)

Hi Servo
I started up in vga mode and the problem went away. unfortunatly I
only had 640x480 res and that aint gonna cut it with mach2. I tried
uninstaling the video card drivers and reinstaling but that didn't
work either.

derek

The symptoms sound much like my PC acts when I have Mach2 and the

Internet opened at the same time. I'm running an Intel P4 3.06gHz
CPU and even with that Mach2 still demands the undivided attention (
resources ) of my PC. If you suspicion that it's the graphics
adapter that is your problem then go to the display properties and
change it back to standard VGA, that will tell all.

Hi Art/Group....In the process of altering the video setup from 32bit
to 256 colour (this by the way has reduced the "shot bearings" sound
on Mach1, I'll try MachII next week) however I now have a "black"
background on the path display. Makes the tool path hard to see.
How to I get this back to white background???

I fixed the hard bits but mucked up the easy bits!!

thanks for any advise.

Don't know what Video card you have but I had similar problems on my Compaq laptop with a ATI Radeon 7500. Switching to 1024x768 or 1280x1024 resolution (from the native LCD 1440x1050) and disabling some graphics features (settings\display\settings\advanced\troubleshoot blah blah) did the trick. Turn down the functionality to minimum and crank it back up notch by notch.
I find some programs are really unhappy with LCD specific resolutions and advanced features, many Dos legacy programs like MasterCam flat out refuse to tolerate them at all.

Mach2 will work at any res. for me, but enabling the fancy 3D stuff results in some pretty weird looking toolpaths and a choppy cursor.

Hi Art and others

I noticed that during the execution of a move, if you toggle between
screens the pulse output is interrupted. On my machine if your
going more than thirty inches a minute and change screens, steps are
lost and the motor stalls. Has anyone else noticed this?


I also lose steps if jogging two axis and one of the axis hit's the
soft limits. The other axis instantly misses steps. This also
effects the next commanded move in the axis that did not hit the
limit, it acts as if the acceleration is instant, and steps are
lost. I'd like to know if I'm the only person who has noticed both
of these glitches.


Sorry if these are repeat questions I've spent some time looking at
previous posts for theses problems.

Thank you
Josh

Hi Art 'n All,

First let me appologize for posting to the former forum, I really
must delete that icon rifght away!

I've been reading some "International Correspondence School" books
that my Dad studied, learned from, and eventually became a "Tool
Maker" back in the 40's.

The thought crossed my mind that my CNC lathe should be no less in
any way than a manual lathe. (Of course more in most ways)

Maybe this is already in the works, but here goes;

The manual lathe has a compound rest and with little trouble one can
turn it to any angle and crank out a short taper or chamfer, quicker
than, sh,,,,,,,,,,,well quickly.

How about four hotkeys and a compass type interface? One enters the
angle, a little arrow shows the direction you'll go with the arrow
also indicating the hotkey to go that way. A hotkey at the tail of
the arrow indicates the reverse travel. Instant compound tool rest!??
Well, not instant from Art's view.

Sorry if this has already been covered,
Jerry

Hi Arturo
I'm at home on an XP machine. I'm running windows 2000 on the
problem machine but I don't think it has that option.

I'll check it out when I get to work in the morning.

I may attach them to macro calls so they can be immplemented by me or
someone else as need arises.

Art,

Do you have any plans for adding spline interpolation (G06)and
hypothetical axis interpolation (G07) to Mach2?

Servo

Art:

Good point, hadn't thought of that one....Might even work..

Jerry:

Thats what I tend to call the "Futz" factor. Its when you run 100's of
tests and convice yourself that a problem is connected to a certain function
or event. Only to find that co-incidence can be a very funny lady....,
Happens to me all the time..

Hi Art,
That being the case, my problem with a certain code running in the
wrong direction may have been an intermittant bad wiring connection,
although it seems that the results were very consistant with evey
other execution running the wrong way and other codes running fine.

I did today find a bad connection in that axis.

Well anyway??

Well its getting weird

If I bring up the task manager and open up Mach 2 the CPU usage hangs
around 15 percent. When I load the Gcode the usage jumps up to 100
percent and becomes sluggish. If I minimize the screen size the CPU
drops back down and everything works fine. If I grab the lower
left corner and make the window larger everything is good until it
gets to about ? size and the Cpu jumps back up. The memory is
staying constant the whole time.

Thanks
Derek

Jerry,

Only when the direction changes. The direction line will stay in whatever
state it is in until a different state is set.

Hi All,
Can someone tell me if a direction pulse is sent to the servo
controller, (Gecko), for every step, or only when the direction
changes?

Thanks Jerry

When I started to get swarf in my Keyboard I went to CompUSA and
picked up one of those flexible, waterproof keyboards. The keys are
sealed between sheets of molded rubber. You can pour a coke or a can
of cutting fluid on top of it and just rinse it of and keep going.
Not good for touch typing because of the spongy feeling to the keys
but I can only hunt and peck. I highly recommend it for anyone
needing a keyboard in a shop enviroment. I bought the short one
without the numeric keypad because I have mine on an old monitor
swing arm that I can push out of the way when I'm not using. Here is
a link for you can seek a picture but they are available at many
places on the net, computer shows and retail outlets. Way better
that screwing up a laptop.

I still use an old Toshiba Satellite 4080XCDT PII 366Mhz with 192Mb
ram on XP Pro for bench testing interfaces etc. It works fine at

25KHz

with network disabled. Network polling kills the pulse train. Also
look for a machine that does not share video memory with RAM.

I don't use it anymore in the shop, got sick of taking the keyboard
out and removing swarf particles ;)

I'm now using an old server I got for nothing. It's a 500Mhz twin
Pentium job, with only one processor (twin processors don't seem to
work any more with Mach2) 1Gb of memory and all SCSI drives, it's

fine

at 25 & 35KHz, but struggles at 45. It's also got a decent video

card

with 128Mb memory which helps a lot.

The swarf problem has been fixed by putting the keyboard on a

sliding

drawer under the bench and using a pendant when running.
