OK, I know nothing about gear hobbing, but have seen that youtube video of the little hobber, what kind of work would need to be done to build a cnc version of such a machine?

If not is there a good place to camp close by? We would be there Thursday late or Friday early till Sunday afternoon. It looks like there are two of us coming from SW Wisconsin. Is there any others from the area going? I have a couple of projects that I will need some instruction on. One is an Fanuc AC servo setup with a Pico setup. The other is to setup a follower system; encoder on a spindle and a servo drive at a specific ratio. EG; hobbing on a horizontal mill.

Skimming thru that, the most promising path I see might be in cobbling up something useing sampler, hal_sampler, streamer and hal_streamer, if the output could somehow be dumped, not to a file, but to a #<_named> memory variable, which could then be massaged in gcode and used as an -z[#<_z_arg> + #<_derived_offset>. in the G33.1 invocation. Has anyone actually done that, that someone here is aware of? > On 9/29/2016 4:11 PM, Gene Heskett wrote: > > On Thursday 29 September 2016 17:00:20 Gene Heskett wrote: > > > > This question may have the genesis of a clue in the Integrators > > Manual, unforch the copy available on the web page, development > > branch dated about 2 weeks ago, is not in English.
