Tool Table setup with angled bits

Hello all, I am relatively new to EMC2 and CNC stuff in general but I love it so far. I have several questions relating to setting up a tool table. I have a Fireball V90 CNC from Probotix that I am using with a Bosch router. The router has some angled bits (v-bits, etc.) that I would like to be able to use and I also have some angled bits I got from www.drewtronics.net specifically for making PCB boards. How do I enter these tools into the EMC2 tool table in a way so that EMC2 will know that they are angled and not just regular end mills? Also, when entering regular end mills, I am trying to follow this guide: wiki.linuxcnc.org/cgi-bin/emcinfo.pl?ToolTable but in the actual EMC2 tool table wizard there is no parameter for length just a field that says "z". I assume this is to be treated as the length value? And finally, is there a way to set a maximum feed rate for specific bits?

Thank you,

I'm no cnc expert but I do a lot of pcb routing and I think it makes no difference to EMC2 what shape the pcb router bit is, all of the important stuff is done by the software that converts the pcb file to G Code.

The most important part for routing a board is to get the pcb as flat as possible on the router table and to zero the Z axis tip of the v-bit exactly on the surface of the board.

An experiment with different angle bits and cut depths will soon find a working formula. Once you have got it don't change it
