 So you just want to rotate not a problem right click create a blueprint actor aim it open it and under add add whatever mesh you want to rotate then under the event graph delete everything and under variables add a float call it whatever you want but it's going to control our rotation apply save set its default value to 100 drag it in and get its value and from this point forward anytime you want to create a new node right click so right click to get an event tick right click to get a multiply right click to get a make rotator and right click one more time to get an add actor local rotation drag them all in like so apply save and you're done the cube will now rotate at a speed of 100 on the y axis right now it's spinning on the y axis because that's what we dragged it into but if we wanted to make it rotate on the x axis we could have easily dragged it into the x axis instead you can change the speed anytime over here and that's really all there is to it hope that helps and as always if you have a fantastic day and I'll see you around.
