G-Code, CAD, and CAM discussions / LCam with Inkscape
« on: November 29, 2009, 06:39:35 PM »
Hi Earl here
Have posted a few times now and
You helped me out getting into Inkscape.

Now problem...............
I take an image and place into my work area on Inkscape, then I also add an area of text.
e.g. Emma's Room
Now I want to turn it all into a workable DXF file.
I seem to be hit and miss on being able to do this.
I try to select all then  path/trace and not seem to be picking up
Other steps involved?? find edges before tracing.?
Could you explain one more time.
I have also been playing with CamBam but thinking that get used to
 Inkscape, then Lcam then Mach should be lots to deal with
Thanks for help
ps Been doing some awsome image only engraving of Wile Coyote and the Lightning Mcqueen car and Ariel

General Mach Discussion / Table layout Y direction in Mach
« on: November 21, 2009, 11:03:24 AM »
I am wondering if I can layout my Y axis from top left corner instead of bottom left as my tool starts home position in top left.
Then I would also have to layout in L-Cam too or CamBam or ??

X is ok as tool moves from left to right.
It is my table that moves. When homed the table is towards me and tool is at the back left corner.

I would like to be able to just place my work on the table to the left and away from me and go.
My thinking is the table has to move all the way back before the tool is in a start position.
If it could start near the table start position would save movement time??
I have permanent edges on the left and away sides of the table and slots in table to hold work in that position
((old dahlgren engraver)) 12" x 24"
If leave tool position at towards me then I am reaching under to place material on table which is away .

Any thoughts would be appreciated.
I think I confused myself even more.........Still wiring up the motors and board....

LazyCam (Beta) / removing chains and entities
« on: October 23, 2009, 10:38:00 AM »
Ok here I go again.
Am bringing in my image oops DXF into Lcam.
Looks good have double lines etc.
Have removed a lot of the lines and speckles with rem objects.
very time consuming.
I also want to remove some of the entities in a chain
example #664 to #702 in chain 24
To do one entity at a time will take quite awhile.

Is there a way to select multiple objects first or multiple entities then remove?

LazyCam (Beta) / Drawing into LC and then to Mach
« on: October 19, 2009, 02:49:24 PM »
I have been trying to process a coloring book drawing jpeg  of Arial the mermaid

From what I have been reading in various threads is to use a cad program to DXF or DWG then to Lcam
and then to generate gcode.  Lcam has import for jpg or bmp but when I try to load it asks to v drill
or raster or image trace/raster. choosing the last option seems the only one that even looks like the drawing.
Now when I generate the gcode to Mach looks like a straight line.

Is there a way of bringing in the jpg to Lcam and adjusting it and then creating gcode for Mach

I have been reading everything I can and might be missing something.
Andy help is appreciated.
