Did you fix the problem with your motors not reversing?

Cold Fusion · #**134** 06-13-2004, 11:05 AM

Not yet. I'm mostly working on the mechanical side of things now.

Router Mount from Kong. Sorry for the quality but the weather is just terrible and the garage doesn't have proper studio lighting

Cold Fusion · #**136** 06-13-2004, 06:52 PM

Bearing mount and ball screw mount, also from Kong.

And finally, the Y axis ballscrew.

Well done CF

!
What pitch is your BS?

Cold Fusion · #**139** 06-13-2004, 07:16 PM

8mm on the Y and 20 on the X. I've ordered some pulleys to even out the gap so it should preform well. Most of power from my 700oz steppers won't even be used because I cut plastics and light wood.

CF: I thought some software had problems cutting circles if you had different pitches on X and Y? (Not sure if this is an issue or not but seem to remember reading it somewhere)

Cold Fusion · #**141** 06-13-2004, 07:34 PM

I never heard of such problems.

IJ. · #**142** 06-13-2004, 07:39 PM

CF: I can't remember where I read it and am still trying to find it!

I'm sure if it's an issue one of the resident Guru's will jump in and let us know. (sorry for any alarm if I'm wrong)

CF: Found it and maybe it's only a DeskCNC thing >>

Pitch Thread
Post #7 onwards.

Thanks IJ!

After chewing through the info it looks like it won't be a problem. I'll be using Mach 2, which I'm sure works with elliptical interpolation. The only limiting factor is the cpu speed, but who needs to cut a circle at 250ipm?
