What do you use to create the Gcode? LazyCAM?

what profile do you use? Mill?

Artcam!

George,
That´s awesome.
What do you use to draw the lines? What software?
I know I can perfectly control the machine with Mach once I have the gcode generated.

Adobe Illustrator.

Yes, I did think about it. I know there are two ways to do this. Either to change the resin dispensing rate using another axis for the dispenser or to keep that fixed and change the nozzle speed so the same amount of resin is dispensed in a longer (or shorter) line.

If I use the variable dispensing rate, this would be the 3rd axis since besides this there is no Z. At a constant dispensing rate the dispenser on-off is not an axis. Is this correct??

I need to be able to start with a graphic image of what I want to dispense resin on. The idea is not to write the Gcode.
I wonder if this can be done with LazyCAM or not. If not, what should I use instead?

Dear Roman 9999
Take a close look to this video.

You have to draw the path your self to have these quality of dispensing.
I keep the feed rate stable.... major rule.
 and when I have to fill the more wider parts of the letter I design one more little path only in that area.

General Mach Discussion / What material is this??? Extreme high speed rate

« on: April 30, 2009, 05:17:02 AM »

I wonder what material is that?
Why the end bit does not broke?
How the hell can a machine milling in that extreme high speed?

after this I think that I am so slow......

Hi, really nice Logo.

How long to machine with so much details.

Jeff

thanx alot for your comments!
It takes about 2:45
1/16 ball nose (for the "U"
V-20 degrees for the stars and letters!
flat 6mm for cut.

George,
What did you end up using for precisely dispensing the resin?

Great work, i love to see machines controlled by mach3 that are not lathes and mills.

Regards
Fernando

Hi rFernando!
I design and machining this small press head and I connect it with a an air piston 20mm.




The last 2 months the machine has to make about 200.000 times the "down/open ---- up/close" move (since I have to make a very small labels).
It works fine !
Sorry for my terrible English.
George!

Hi George,
  Great machine!
   This may be a dumb question, but does your machine "find" the
object to dome with the cross hair laser light seen in the video?
  It appeared that you laid the second tray on the spoil board
without aligning it or fastening it to a pre-measured spot. How does this work?
  Thanks,
  Glenn

The set of icons are vertical &horizontal align. I move the tray to happen this.
1) the first icon to be in the center of my tip.
2) the aray of the icon be aligned with laser lines

RC
The parker OEM 750 are very good drives with impressive characteristics and 3-4 times more expensive than Smooth Stepper
 plus they can handle 75VDC 6-7Amp That means speed and power.
http://www.arcetri.astro.it/irlab/doc/OEM750%20User%20Guide.pdf
I think that I push them to hard. Or my PC is slow (3.2 Ghz with XP).
Or maybe the power supply is small (75VDC 10A) maybe I need 20A.
the 3 drives is configured to give 6.8A/drive.
George.
