Hi Jackal,
First, thanks for the welcome.
Yes, I will take all the help I can get. One thing I want to do is install one of those PID Electronic Speed Controllers on the 7518 Porter Cable router that is included with the Shopbot. Currently it is set up with 5 speeds. 10k, 13k, 16k, 19k, and 21k. The PID speed controller bypasses that circuit and allows you to infinitely vary the speed from 5k to the max 21K (without loss of rpm under load). I want to cut some plastics with the router and slowing down the spindle speed will be a BIG help. They also say you can control the router speed directly via Mach3 software in conjunction with their PID Speed Controller. It is only about $165.00 and if it works like is planned it will be a good deal. They have a few You Tube Videos on their website that show the unit in operation.
The Shopbot PRT 48 X 96 that I am getting is setup for use with 2 spindles. One in front of the other. The gantry is extra wide to accommodate them. The second router he has for the router is a Makita RF1100 which is supposed to be one of the quietest routers on the market. He says the speed controller is burnt up on that one so it will also be a good candidate for the PID speed controller as that circuit gets bypassed during the installation process.
