find a best way to cut card board about 24 to 50 pts

[avengine]

I have the Cam tech Routermaster52 xyz router table 52"x102" with a cmc1 controller (very old only has 100k ram inside to hold the plot file), I want to upgrade the machine with a tangential knife option to cut card board and corrugate.
Is there any company sell the hardware add on and software to add into the head. I don't mind to change the controller if there is a solution to make the thing easier for operation. I want to use this table as a learning tool to find better way to control linear motion for graphic use, if you know any link related to my dream machine, Any suggestion welcome.
can contact me direct at output123@gmail.com
Thanks.
