MicroRouter Spindle upgrade - advice and help required

[ngwagwa]

Hi, as will become apparent I am new to all of this.

I have aquired a Denford MicroRouter that has been modified to run on Mach3 using what I believe is the original Cable Porter spindle. What I want to do is fit a new spindle with an ER collet so I can use smal (1.0 dia) cutters to finish components that have been semi-finished on a different machine. As I would still like to use the router for machining wood I would ideally like to find a spindle that will run off the existing electronics.

The on/off and speed of the spindle fitted is controlled by a Spindle V5 board (https://0201.nccdn.net/4_2/000/000/0...spindleV5x.pdf). I have attached pictures of all the other internals in case information on them is needed.

Any help/advice greatly appreciated.
