Hi Rich:
Just to be sure we're on the same plugin , I publish it here.
My results show the RPM is much more stable under the advanced threader plugin. It shows a normal RPM of 393-395RPM fluctuating constantly,
the advanced threading shows 393.50 to 393.6 RPM and very steady. This fluctuation could accoutn for a highe rpitch error at low RPM, and lower error at high
RPM due to the fluctuation being a smaller % of the total RPM, and your testing seems to point directly at that possability. If this can be confirmed, I will simply
change the single point threading to measure the RPM based on time, not # of interrupts.
Here is a photo of my advance3d threading run, both Timing and Index inputs are enabled and both are set to pin 15 ( my index signal).
I ran a test thread in the air and all runs fine, so I suspect you can thread quite well even with one slot per rev which is what will display under such a setup.
Im of the opinion that it isnt necessary to have a slotted wheel, though it may make things more accurate as instead of being one rotaiton behind, the corrector
will be one slot behind.
Let me know how it goes..
Thx
Art
