Importing from Rhino to Mach

[gregrnel]

I'm a total newbie, so be gentle.

I'm just trying to do some practice runs in Mach with a DynaCNC table, when I import the attatched dxf object into Mach I get a very strange broken up object. Any hints as to what I'm doing wrong?

Thanks in advance!!

2D .dxf's only. Export the profile only, not the whole 3D model.

Hey, thanks ger21.

I've tried every combination for saving the file in Rhino as the profile only and nothing seems to give me a clean g code in mach 3. Any idea how I do that in Rhino 3?

Once again thanks in advance!

You need a simple 2D outline of the part. If you can't extract that from within Rhino, can you redraw one?

Try this. I used make2d in rhino to get you a 2d dxf. 2d is all Mach will see.

If you are wanting to carve the 3d body download the trial version of Madcam and give it a try. Meshcam can also carve it but it doesn't, or the last time I tried it, did not do vertical sides too well. Madcam has both 3d and 3d capabilities.

Hey guys, thanks, I'll give it a shot.

So am I to understand that I cannot use mach3 to do a guitar neck or an arch top because it is only 2d?

Once again thanks in advance!

You can use Mach3 to control the machine for 3D parts, but you'll need something else to create the g-code. You might want to look at www.meshcam.com

Thanks for all your help, I'm too much of a newbie to have known that Mach3 cannot generate 3d g code, just another example of poor service and misinformation brought to you by DynaCNC, but I'll save that story for another time.

I am really surprised that someone at DynaCNC told you that Mach3 Imported a 3D file. I have had conversatins with them about 3D files and they told me to go for the BobART plug-in. They told me that Mach3 did not import 3D files. I think you mis-understood the direction from DynaCNC.

To reinforce what Gerry said.....yes mach can do 3d. I machine 3d all the time, and I use Rhino for the modeling and Madcam for the cam. The guitar you posted can actually be done quite easily in 2d rather than 3d. You will need all the pockets modeled but other than that you just need to get comfortable with Mach.

I in an "extended" process of building a bass for my brother and the only 3d I will do on it is the neck. Everything else will be done with 2d.

ps in the musical instruments forum check out the "Lets build a Strat" thread. You might find it interesting.

MeshCAM will work nicely for you. for something slightly more expensive (and probably a lot more versitile) a lot of the guitar makers out here use MadCAM which is a pluggin that integrates directly into Rhino. There is also (on the ridiculously expensive end) RhinoCAM (the one I use) which is also a plugin and also integrates right into Rhino3D. RhinoCAM has a few free viseos to show you how it works.

There is also another thread here called "let's make a strat" or something like that (just do a search for it). The g-code for the neck is there ready for download.

termite is rite i am journeymen patternmaker powermill , visualmill etc. rhino and mad cam can do anything dont make the same mistake as i did and buy rams gold for 1100.00 and its a joke i could not believe sales pitch, i cant give it away , tryed to sell for 400.00 and i still have it.only good for 2-1/2 d
