I bought Series II interact 2 some 3 years ago. Ran it on TNC145 control till 5 months ago when I changed it with Mach3 and AC servo motors. The old control was working fine. Switchover was because I needed 3d contouring and bigger gcode files on it. Otherwise TNC145 and original DC servo motors were running perfectly. It's mechanical structure is in excellent condition for a machine dated 1985-86 or so. After switching to Mach3, I am thinking why didn't I do it earlier. Productivity of the machine has increased remarkably due to Mach3. I am putting together a 4th axis these days for this machine.
