I am currently retrofitting a wood mizer LT40 with traverse and up/down head with a CNC controller. The controls are Allen Bradley PLC with servo cards and a touch HMI with Servo Dynamics/SEM amps and motors. I have included some other features with the I/O : blade speed, blade tension, and an output to run the coolant. How are you coming with the Linn - I watched the video..doesn't take a very big servo if there is a gear box. I retrofitted a hydraulic head couple month ago. Used a rexroth +/- Valve and a micrologix PLC. Worked well.
