Zeroing Bits

[kubotaman]

I have a Shopbot ATC and am getting quite tired of putting the ground on the bits and then applying the zero plate to tell the program where the surface is prior to cutting. Most all the newer CNC's have an automatic way of zeroing the bits prior to cutting. Is there a way that ShopBot has eliminated this procedure and made it less cumbersome. The bit is not grounded on my HSD spindle which makes it harder to do automatically. Any help is appreciated.

Shopbot sells a pressure touch plate that you could mount and not have to attach the ground to your bit

Jerry Ill call them and see what they have. Thanks!

I messaged them yesterday asking for a quote on the Z-zero pad. Hopefully I'll hear from them today.

Ordered a fixed plate for my ATC and a non fixed one to replace my aluminum zero plate. The big spindle with the ATC uses ceramic bearings so the bit is isolated from ground. Thus the need for the alligator clip on the bit to z-zero. Hopefully i can get rid of the ground clip with the pressure plate.
