I use standard bits all the time. The key is, if they are large ones, you will need to slow the feed rate and take a smaller amount each pass. Other then that the router can handle it, it’s just the stepper motors are only so strong with the belt setup. I use large V-Bits, and a 1 1/4" surface bit often. Also Ball nose and straight bits for clearing / roughing. Just take smaller layers and you should be fine. The largest issue is if you push down too hard Z belt will skip and if moving too fast with the larger surface on the bit it could cause X or Y to skip.
