Spindle Speed issue

Hi ,
I have had my nomad for about a year now but have only used it 20-30 times , it was working perfect about 6 months ago before I stopped using it for a bit. But I’m getting back into it now , and the spindle speed has been off it seems. Im using meshcam and when setting up my parameters I’m setting the spindle speed to 9200 for AL roughing and on finishing I’m setting it to 9200 also, running a .125 bit. But If I switch over to roughing specs again and back to finishing it keeps changing my spindle speed to 5000. I tried to run it anyways , While doing the roughing work it seems super slow , so I put a tach on it and it seems to be spinning around or just under 5k . Any ideas how to fix this ? thanks
