New version 4.90.03 -- 4th axis

[Mooselake]

Art, from watching the first half or so of the video (sorry, got too late and too tired) it looks like it might be possible to build a gear machine that only needs driven X, Z, and A axis, and neither X or Z need a very big range.  Y, the displacement of the A center, could be manual since it doesn't change.  Is this true?

Kirk:

  Actually, in tangental cutting you need all 4 axis to move, the Y moves for tangental motion, the X to cut across the blank,
and the Z for depth...then a for rotation.. all 4 at once at times.. ( though only small motion of x,y,z are possible )

Good point, as you know I use only metric,  I will run inch this afternoon to correct any issues..

I'd already taken another look and realized I was wrong    It'd still be a fun project.  I need a 110 tooth #40 chain sprocket for my hay mower, the price from the dealer is almost enough to build a machine to make one, and the project has been on a mental back burner for a couple years.  Openbuild extrusion and plates might make if fairly easy.

I'm stuck in a knee CPM machine for the next few weeks, lots of time to plan while I'm sitting around.

  Well, on the bright side you can now do sprockets on 4th axis, but due to the way the arcs in a sprocket work the rooting is fairly nasty, BUT with a very small depth per pass , it will actually do a pretty decent job at a sprocket, just some dressing with a file
I suspect.. In most 4th axis work under the new system, you can get alias artifacts on all but involutes, that will be typically approximately the size of the depth per pass settings and can be dressed away Id think....This is why I never allowed sprockets
and such in the past, but then as someone pointed out to me, better to have it half or 3/4 ass'ed than not at all..

How do you rotate the object(s) on a laptop with no mouse?

System just crashed after deleting objects from the project.

I generated two identical 18 tooth XH pulleys, Played around with the new 4th axis screen and then deleted the two objects from the project.

Upon deleting the second object the app displayed an error and then shut down.

Randy:

  Thx, I have found several of these where deleting the obnjects causes a crash..thought I had them all , Ill dig deeper.

Good point about the mouse, I will add the arrow keys tomorrow as options as well, the ctrl and shift keys are currently
modifiers if your mouse has no buttons..

Any chance you will support 3dconnexion? I love mine. Makes it so much nicer to control in 3d.

Craig:

  I may.... Ill look into the SDK to see what it woudl take..
