this file you posted has no any settings but spindle rpm..
the generic g-code from any cam program should work..
you might edit the g-code postprocessor, or ask help on proper forum..
on artcam forum on the verified area even you can find posts about this..
the reason for this barebone codeing, because youll set federate trough on the handheld unit..
I would suggest you contact machine seller and buy an ncstudio control.. or a mach3 control for your router..
both of them low cost and worth to replace the dsp control..
ncstudio, works with separated processor ... for 3 axis works very well

if you have more than 3 axis you can try the mach3 control

===========================
I think the dsp control was developed avoiding a costly computer kept busy with router control.. since that computers are got on very low price so theres no more reason for the dsp control...
