I currently have a 1000 PPR encoder on it. And that rigid taps great. Ideally I would like something similar
How fast can those sensors read? 1000ppr at 10k rpm would be great But just thinking about it. I only actually need to be able to read encoder up to say 2000 rpm At high speed it doesn't matter On Sun, 27 Mar 2022, 22:21 Andy Pugh, <bodge...@gmail.com> wrote: > > > > On 27 Mar 2022, at 08:09, andrew beck <andrewbeck0...@gmail.com> wrote: > > > > And is bigger dia better for higher resolution? > > Probably not, as it will perhaps have more scope to oscillate at 10,000 > rpm. > > Don’t neglect the purely mechanical design of this fast-spinning part. > > Have you considered optical sensors rather than inductive? > > What will be counting the pulses? > > LinuxCNC can lathe-thread with one sensor. > But rigid-tapping is different as it needs to accurately detect the > reversal point.
