Checking belt tension

I know I read a post where someone said to check the tension weight on the belts again after the first couple hours of carving, but beyond that how often should I test the tension? Don’t want to over do it and help stretch them by checking too much. Doing some wiring in the garage tomorrow to put in a couple new outlets I desperately need now, and want get it done before a few hours of carvings tomorrow. Also, wondering if everyone gives their machine a cool down period or break between carvings? I have 5-6 I need to get done, but have a few days. I was going to try and knock a few out tomorrow but don’t want to over do it.

Its just too funny!!! :joy::joy::joy:
I am so far from belts i completely forgot all those troubles. I barely have to do any checking. I’m definitely spoiled!
