I think you may have to be the pioneer on this one Bertho.

Looks like you have all the info on the heater heads and 4th axis feed - go on and give it a try. 

Please keep us informed with your progress - I, for one, am anxious to see the results.

Hey Jeff,

Loads of questions please....

What software did you use to create the toolpath ?
What was the depth of cut and spindle speed and feedrate ?
How long did it take ?
What size is it ?

Many thanks,

Tweakie.

Hi Marcel,
I cannot modify the .stl. I don't even know what program was used to create the .stl it was just downloaded from the Zone.

Hi Jeff,
Absolutely brilliant, so much detail and wonderful finish.

Hi Gerry,
Thanks for the info. I think you should cut a tiger now, just to make up the set.

Hi Mahesh,

Sounds like a very interesting application which, I think, Mach3 could handle with ease - it would work just as well controlling one axis as it does controlling six. Good fortune with your project.

Excellent work Gerry.

I think a feedrate of 155 ipm would scare the pants off me using a cutter that small. If you can recall what depth of cut and spindle speed did you use please ?.

I managed to take a better photo of my tiger (without the flash this time).

Many thanks Gerry, much appreciated,

I am not planning on installing/running MeshCam until my DP 30 days are up then I can spend more time learning it.

One thing that comes to mind having made this is that the 70 x 70 tiger took 3 hours machine time - whereas a skilled woodcarver could, i think, have made this in considerably less time (and possibly even, done a much better job). Metalworking is probably where the major benefits of 3D CAM prove to be of greater advantage. So may try a metal object with MeshCam and use the mill instead of the router.

Who's this "Chris Botha" they reference to in the instructional videos???  Wink

Hey Sam, He seems to have done a runner from the forum lately - missing the excellent pics of his work I am.

Thanks for the tip Gerry - The MeshCam software is indeed a fraction of the price and has a free 30 day trial.

Yea Barry, you are just showing off because you have more axis than I have milling cutters.

Incidentally, the toolpath for this tiger was created from an .stl file using 'DeskProto'.
The company is offering a 30 day trial version for download from their site here:- http://www.deskproto.com/
For those who have not seen it - the program is pretty basic (which makes it easy to learn) but incorporates most of the features found in the big boys programs including 4th axis capability.
Not sure if I will purchase it yet though - think I may run a few more 3D files before the 30 days are up.

Soldering is not good . should use crimp ferrels.

Sorry Ed but don't agree with this one in general, however the lead free stuff is rubbish (which is perhaps why the 60/40 tin/lead is still used for military equipment in the UK) and crimps would be better if you can't use 60/40.

Nice diagram Barry (I have pasted a small copy of my diagram on the inside of my control box door for reference).
