LOL...Missing decimal point. OOps!!!! I guess I missed that one. D'oh~! :pinch:

Regarding the N-code...
I write the code in an excel file and use the N -code to help me keep track of what line has an error on it. (Granted, the LinuxCNC gives me a message stating "near line ### " but when I open up the file, I can do a quick [Search] to find it.

Progress Update -
Okay, I *have* managed to get the triangle completed~!! However it isn't perfect. A have a bevel in the bottom left corner and a slight bulge in the bottom right corner. I reckon I need to do more tweaking and see what it gets me.

Thank you *very* much for the assistance~!!!

PS - In this new version, for me, the [Quit] button no longer quits/exits the program. (shrugs)

Odd, the Quit button works for me. You are using Ubuntu 10.04 right?

If this is a simple triangle with rounded corners you might have better luck drawing the triangle in Qcad then rounding the corners and getting the start and end points and arc locations and translating that to G code.

Qcad? I can take a look at that, thanx. (Hopefully it is free!!)

I'm not a graphic artist, nor a programmer. I've sampled with Inkscape and maker cam, and they seem okay but because I cannot fully use/understand them I think using Inskscape is akin to using a sledgehammer to drive a finishing nail.
Makercam is okay, but half the time the pocket operations don't work out, and with some of my drawings, the program crashes.
I've recently downloaded HeeksCNC and WINTOPO. Heeks seems to work, but intermittenly - I know the problem is on my end as I am struggling to understand this program. I'm using WINTOPO to convert my drawings from JPG into a DXF format to import into HeeksCNC, and at least I've got that one working well!

In the interim, I continue with programming everything by hand, using Paint Shop Pro #6 and Microsoft Excel

Take a look at the image below :
I start with a template image that represents graph paper.
Then I add one layer at a time, each layer representing its own function.
Example =
one for cribbage pegs-holes
one for borders
one for curves
etc...

Legend for the image below:
Pink grid: this is the background; 1/32" (.0312") spacing.
Blue 'plus signs' and numbers = 1/8" (.125") drill points & series indicator for "Player 1" (NOTE:Green is player #2)
Black line; initial edge
Light blue line: cutting edge. The space between the blue line and black will be beveled on my table router
Red 'Plus signs' indicators for the 1/4" (.25") router bit.
Purple circle: lining up the rounding of the corners.
Black 'Plus signs' = router bit indicators I can copy and past in the image as needed...

Then I look up the X and Y references on the sides, and type each one in to excel, each letter and number gets its own cell (example 'X' in one cell, and then 1.0625 it the next one)

Yea, it is a *LOT* of work. But it works, and I'm not the kind of guy who can sit and understand text manuals. I really try, but I have to be told preciesly what to do, or shown. :P

That's quite a tool chain. For accuracy I prefer to not involve bitmap files in my CAD CAM process.
I created a triangle in Qcad and rounded the corners then got the dimensions I needed to use ArcBuddy to calculate the arc.







If you create a layer for each thing then you can turn them on and off to unclutter the drawing.

The whole triangle. Also I would place a point at the XY 0 reference to dimension from.

Wow, I'm sure that took you no time at all~!! B)

I did look up the Qcad website, and I guess I can download it and give it a try. If it is the commonplace tool, thenafter I go through the documentation and tutorials, I have somewhere to search for answers. ;)

Thanx again!

Actually you can install Qcad from the Ubuntu Menu
Applications > Ubuntu Software Center
in the search box type qcad
look for professional CAD system and install qcad, qcad-data, and qcad-doc
then right click on Applications and select Edit Menus
pick a spot and add a new item with the command qcad

I'm not sure at this point how to get the docs to show up.

This local link should show the docs in a browser if you installed them

file:///usr/share/doc/qcad/html/appendix.html

Groovy, thanx~!!!

I've already downloaded it to my Windows 7 notebook, and I'll try to play with it some while I'm away.

Thanx again!

Once you learn the method to drawing lines exactly where you want your GTG.

Snaps:
Snap to grid to start a line at 0,0 (look at the status bar to see where your cross hairs are)
Snap to end point to start a line from the end point of an entity
You toggle back and forth on the snaps as you need them.

Parallel lines is great way to make rectangles, start with two lines perpendicular to each other then parallel off of them then trim the corners with trim one line.

To draw the triangle I made one line horizontal then snapped to the end with a line with angle to get the angle I wanted. Then I just trimmed the ends (didn't need to really but a habit) then used round to put a radius on the corner.
