I've looked at a timing [type] belt and I now believe that it is problably a
better option than my
rack and pinion, however I've never been able to get accurate details on belt
stretch and therefore
don't know how accurate the assembly would be. In most instances it would
probably work fairly

A toothed belt drive might be much cheaper and good enough?

The Backlash is very small on the R/P [I can't measure it] but it does wear
out over time [I'm on my second set of rack and third set of pinions] I've
decided that it would be a better system if I moved to the ballscrew or a super
hard helical R/P. The ballscrew came out cheaper so.. that's whe

If the rack drive has no backlash and is strong enough to handle the
cutting forces there is no reason to go to a ball screw.
The bidirectional lead screw compensation works very well.

Thanks Steve, this was infact my plan. I've got a bunch of G202's and steppers
sitting around. It would
be fairly simple to load it up and start playing and get my feet wet that way..
we'll see how things progress
from there. I'm several months away from any major changes on my machine..just

Hey there Aram, I built my own router. I work as an industrial designer
& build heavy equipment for steel mills and the like. Designing and
building my own machine was a natural fit. My router is 20 x 10 [ft]
and has ~30" of Z travel [which will soon be more like 50"]
I've not yet built the B/C ax
Hi
I am interesting in your router. Did you build that router by yourself or
retrofiring existing one. What king head A and B axis do you use.
can you send me link from internet that describe your A and B axis?
How big spindle motor do you use?
Thanks

However not being a programer of any depth, I'm a little leary of taking a
working machine and trying to convert it to linux and possibly ending up w/ a
