Sweet, thanks, I will try that!

I wish I could join in the fun, but with no machine yet, all I can do is watch! Anyhow, I've been learning 3d Cad in my spare time, and came up with a nice frame for all your pictures. It is for an 8"x6" piccy, with the actual frame measuring 10"x8"x1.25". There is a recess for the picture, leaving 1/2" of wood beneath. The x,y axes zero's are at the bottom left of this recess, z=0 is at the bottom of the object. You can get the STL file HERE, if anyone's interested that is!
Like I said, I'm only learning, so any suggestions would be welcome.
Sweet, thanks, I will try that!

I wish it wouldn't crash.
Jim - Those are exactly the cutters I was refering to. Thanks for the link.
Rcrabb - The up and down moves are the result of the constant-z algorithm. Since many of the cuts are unconnected due to "peaks" that rise to a higher level. The easiest, and therefore most reliable, way to connect them is with a retract and plunge move. This is not optimal, but the whole idea of the roughing stepover being tied to the fininsh stepover is pretty nonoptimal. This will be completely redone in the future with a better algortihm.
Balsaman - You've convinced me to add an "Advanced Toolpath" command where you can specify a different tool for each step. It's, in my opinion, of somewhat limited value since the roughing algorithm is not efficient (as described above) . It's been request enough though that I'll do it anyway. Also I changed the toolpath command to run the zmap command if you forget to (Per your reqest). I'll try to get a new version out in the next few weeks incorporating this and a bit more.

Robert I sent the rhino file to the yahoo board. Did you get a chance to view it. It is a 3dm file and I use v3.0.

No greater love can a man have than this, that he give his life for a friend.
Can you also post the STL?
Will do Robert. I did finally get the stl to load into Mesh but am having problems setting up the part for machining. I need only to machine the surfaces and do not want the bit to fall over the edge anywhere. For instance if the stock is oriented with the left side up, I only want to machine what you could see if looking down from the top. Does that make sense?

I think what you want to do, and currently MeshCAM won't allow it, is to make your stock smaller than the actual part. Robert, how hard would it be to be able to set your stock (X and Y only, I think if you changed the Z you would run into problems.?) to be smaller than the part, and specify the offset in X and Y? This would have the added benefit of being able to machine any area of the part that you wanted. What do you think? At the very least, maybe set up an option to not go outside the stock size. Deskproto has a couple different options for this. They call the part of your stock that is outside your model ambient, and let you configure the depth of cut for this excess material. This would also address the problem, by allowing you to cut only the top face of the model by specifying not to cut this excess stock.

I just read Robert's development log on his site and it looks like the next beta will address this stock issue I just talked about.

Yeah, I've got a totally new way to specify the stock and position. You'll no longer be limited to the size of the geometry, and you'll be able to move the stock off of the geometry. I think it'll be a step in the right direction but I'll be looking forward to everyones feedback to handle the situations that I haven't thought of yet.

On the finishing pass you have a choice to cut on x axis or y axis or both. I recently ran the dragon file from homecnc's website and his finish pass ran diaganol. Is there a benefit from a diaganol finish pass? It seemed to have a nice finish. If there was enough interest could that be added to meshcam?
That is a pretty big change. Given enough interest I'd look at adding it. I'll add it to my list of requests to keep it in mind.

The advantage would be hitting 90° corners/edges. A diagonal criss/cross patter works best for 95% of the finish surfacing I've done.Originally posted by rcrabb
