Lower RPMs on the VFD for edge finders

It would be be nice to be able to go down to 1000rpm (or lower) so that we can use edge finders. I haven’t received my VFD so I’m only going off the order page but it looks like it only goes down to 8000rpm. Is there a way to go lower for that specific use case?

The spindles don’t really work at that RPM so there’s not much we can do about that. Other users have had good luck with the conductive edge finders rather than the mechanical type.

Ah gotcha. Any recommendations on conductive edge detectors? Or maybe a knock off haimer? I’m having a hard time finding an electronic one small enough to fit.
