Question #: 14276

Question: Which controller(DSP or FPGA or other) is best for CNC machine for G code interpreter operations?

Current Solution

It's probably better to use an FPGA or a microcontroller that is clocked (provided by a crystal oscillator) fast enough to simultaneously output pulse trains for the number of axes you intent to drive on the CNC and to provide for other processor operations, like spindle control, processing inputs from the machine and other outputs you may have (mist, coolant, etc.).

Additional Information:
Thanks for the information.
Some CNC controllers having both FPGA & DSP. Is there any advantages? What is the role of DSP in this case?
