Router run time

So for all you seasoned CNC peeps in here… How long can I let my Makita router run before I should stop and let it cool off? I haven’t run it for anything over 32 minutes at one time but I have a project Im getting ready to do that is going to require several hours. I realize this is the perfect scenario for the spindle but I have what I have right now, including extra brushes for the router, and I can’t upgrade just yet. Has anyone burned up a router doing long run times?

Thanks for your help

we’ve run it for days, you’ll be good.

Ok just checking. My stepper motors are 120 degrees and my router is 105. It just seemed a little hot to let it run like that but if you think it’s good then i will keep going

I just ran mine for for about 30 hours and had no issues. Temps are in the 65F to 70 here in western New York.

For anyone running extended periods of time, spare brushes are a must and a spare router is advisable, just to minimize inconvenience if it happens to quit in the middle of a long project.

Where does one get these brushes?

I got mine on Amazon:
