Eloquently put "Torchhead"! Thanks.

??????????????????

Could someone elaborate on "Al2 O3". Where can you buy it, how is it mixed, and so on? Thanks

Having a bit of a problem uploading.

Ok gents, here is the g code for a mandolin f5 top. I will provide the inside and back soon. Use a 1/4 inch endmill for each file. Lots of hard work to get to this point so I hope you all...

Wow.

Using roller chain and sprocket for axis drive.

Sprocket = 0.5" pitch with 9 teeth

Stepper Motor = 200 steps per rev.


If set as above one revolution would equal 5 inches?

If I set the...

Ahhh, yes that looks much better. Do you leave the part you are cutting a bit on the thick side--like for final sanding? If so how much extra would you leave--0.05, 0.1, or less?

I may need to take you up on that offer. I have a Porter C. laminate router on my cnc. I am limited as to the end mill size. I have bull nose and flat 2 flute up-cut mill bits. Do you think that...

Mike,

With the carve top electric bodies do you have the arch going all the way to the edge? I'm not sure if the above top has too much level space from the end of the arch to the edge of the...

Here is the f5 top I made with rhino. I have yet to run live on my cnc. I just got some machinable wax and I'm going to use that first--just to make sure.

Thank you guys. Excellent information that will get me up and running. I would like to go with a larger router; however, I am concerned that the extra weight will put too much load on my stepper...

I am goint to use a Porter-Cable Laminate Trimmer on my cnc. I was using a dremmel but that was too small.

Anyhow, I am going to cut mostly maple and spruce wood parts. I need end mills for...

Wow! Cool down dude. I did not PROCLAIM that your code was no good. I also don't recall you letting me know that I had to change my settings in Kcam. Look, thank you very much for what you did. ...

Easy there...

What I said was I could not get your code to run in Kcam. I also posted the out-put screen so you could see what the program was doing. If you would have continued on you would...

Well, a lot of time has passed since I started this thread but I'm making great progress. I have generated g code for the mandolin top plate but have not run it yet.

Here is a view of the...

I went with Rhino 4.0 w/ RhinoCAM. No pressure sales and the software is the best for my needs.

Like baltman I was called all the time by these guys. Each time they would have this "special one...

You lost me at "...projected it to the cplane".

I am trying to join the scroll to the surface of the mando top and then make everything one solid object. Is this related to what your talking...

Yes. The space between the outside border and the center arch was the problem. I changed it to "patch" and that fixed it. I also cleaned up some other arches that I had drawn as guides. I think...

Wow! Spoiledbrat thanks for pushing me over the edge. I can't believe how seamless the process is from design to machine code. This is great!

I broke down and purchased RhinoCAM and last night figured out that my original model had some problems. That is what was making the gcode output look goofy.

Well guys, I did it. I now have RhinoCAM! I'm sure I'll be back here to ask some questions. I work with it tonight and give an update on Saturday.

I was just thinking on my way home that RhinoCAM is going to be the best solution. Kcam can do simple gcode without any problems but I think the level of work I'm moving into is going to require the...

Wow that was fast! Thanks!

I ran this in Kcam and here is what I'm getting (see attached). Hmmm... I'll work more on this tonight.

Here is the file.

I am considering RhinoCAM.

I have fumbled with low end CAD to try and save a dime for a long time until I got to the point where I closed my eyes and bought Rhino v4.0. I am sooooo glad I did...

I bet that may be my problem. I'll try that a try. I'm using rhino v4.0 but I have not converted into a solid... only have surfaces.

Well at last I have made the DXF of the F-5 top. I broke down and got Rhino v4... well worth the purchase! Anyhow, I could use a bit of help generating the gcode.

I'm going to post what I have...

I zip the last one but I'll give it another go....

HA! I'll try this up load again:
