Router bit not milling full depth

[cropwell]

Hi Kitwin, I'm using the same method I use for all bits I lower the bit onto a thin piece of paper and set it when I can just move the paper, but it's not pinched. Not the best method I know, but it seems to work well enough. I would love to by a zero setter at some point.

My zero setter is a piece of brass bonded to acrylic. The brass/acrylic was turned on the lathe to make the faces parallel and a 4mm hole drilled in the brass for a wire to connect it to the BoB.

I have a macro for Mach3 which lowers the bit (earthed, in my case through the spindle) onto the brass and when it touches it retracts the tool 10mm and sets the tool to Gauge thickness + 10mm, so zero is top of material, bottom of gauge.

If everything weren't packed away whilst I am refurbing my workspace during lockdown, I could send you a copy of the macro and instructions, assuming you use Mach3.

Cheers, Rob
