a broken or loose main lead or burnt out armature.

Make sure the switch for remote power or control at machine is on the right setting. It will arc but very faint if this switch is not on the right setting.

set parameters,check voltage and amperage properly

change the cutting nozzle

Try increasing the feed rate. Decrease voltage also. If still no luck, try checking the wire diameter. If you are using flux core wire, make sure the wire isn't too old and it hasn't been exposed to moisture. If you are using gas, make sure that the gas regulator is working properly. If so, then try getting closer to your work with the nozzle. Distance from your workpiece and wind can interrupt the gas shield, causing the wire to burn unshielded.

Check the 24 volt contactor terminals, the contactor may need replacement. You need to determine if power from the control board is reaching the feed motor. If it is not- the SCR's on the control board have probably failed. They are an easy replacement, but it is a stinky process as Miller varnished the boards. It is going to be a pulsed waveform so an analog meter will work best, set on AC and slowly lower voltages on the knob starting from 250 VAC and going lower until a response is noted as needle deflection, the needle will jump off zero if there is power.
