Add a tangential knife option

[avengine]

I have the Cam tech Routermaster52 with a cmc1 controller, I want to upgrade the machine with a tangential knife option to cut card board and corrugate.
Is there any company sell the hardware 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.
Any suggestion welcome.
can contact me direct at output123@gmail.com
Thanks.

btw I forgot to mention the controller only have 100k of ram, is there a easy way to add more ram into it, or I better off buy a new controller. Right now I can only cut a simple figure about 6" square and repeat 20x. anything more has to be spool to the controller thru serial cable and I can see the router just keep turning on one spot to go to the second instruction. very slow.
I am new to this cnc, please direct me what is the best way and I am open to creative suggestion.
Thanks.

These guys make a tangential system that operates like a 4th axis. It swivels the knife so it is parallel with the cut at all times. Especially good for thicker materials where a drag knife wouldn't work. They also have the sofware for it but they will need to custom fit it with your controller. Try giving them a call.
