Selecting a CNC Cutting Controller

A controller must match the machine’s cutting process, mechanics, drive electronics and software. For a replacement, record the existing controller’s model, hardware revision, firmware and configuration before comparing options.

Define the application

List the cutting processes, required motion axes and any rotary or multi-station functions. Verify each function on the exact controller and software version; a model name alone does not establish which options are installed.

Check interfaces and installation

Compare the motor drives and their required command signals with the controller outputs. Identify the height controller, plasma power source, remote receiver, limit switches and other connected equipment. Check connector assignments, signal ratings, supply requirements and dimensions against the applicable manuals.

Check the software workflow

Confirm the program format and post-processor used by the nesting software, then verify that the intended controller version can use the resulting programs. Preserve existing configuration and machine parameters according to the equipment manufacturer’s instructions before replacing a controller.
