What about thinking more 'old school', like how manually operated tools on
turret lathes were developed to be automated? Your grinding process has a few
repetitive steps.
Unload part from carousel.Load into clamp.Grind.Turn part over.Grind.Unload
part from clamp.Reload into carousel.
If this is
I was thinking the same thing. If the carousel is not yet designed
then build it such that only a simple translation(s) is required to
load the part., no rotation.
The reason you buy the general purpose robot other then the simpler
automation is that you expect to have other jobs in the future.

Maybe use the exact same mechanism as a slide carousel?

If you are buying a new robot then you won't need or want to use LCNC to
control it. There is a big difference in robot controls. Look carefully.
As mentioned most robot companies will do a simulation for you and make
recommendations. If this is for a production machine you need to

The stepgens (both in mesa and the software) have their own acceleration
setting. you want this to be 20 to 30% higher than the motion planners
acceleration. (when using the stepgen's in position mode)
when using high latency systems - then it is best to run the stepgens in
velocity mode wit
One of the most important specs for a robot is the degrees of freedom.
If you need to specify the orientation AND location of the end
effector you need at least 6 DOF. You can use fewer if you can
redefine the problem.

Or search for "hand wheel encoder" (no quotes) it will turn up quite
a few and some of them are black color rather than the bare aluminum
color if you would prefer that.
I'm wondering these were not intended to be used on an electronic safe
as a combination lock.

Hi All,
Has anyone used udoo x86 for linuxcnc? I really want to use the best
combination for 3 axis milling cnc.
Thanks

Folks, I really appreciate the replies I've gotten here. You've helped
me gain a much better picture of what will be involved. Our forecasts
and budget analysis leads me to believe that we could seriously use this
robot within the next year, based on what it will take to put into place.

I must be searching wrong. Could you please supply a link or auction number?

These wheels, it seems are NOT a one time surplus deal. I notice now
they are all over eBay. Many sellers are offering them. Best current
price is $14.49 with free shipping.
