@trucker2215 You can use Bang-Bang mode for the bed heater. Some say it will show in your print, because the bed will bend. But that depends on the flexibility of the bed mounting ( search kinematic bed ) and thickness of the heat spreader.

Have you PID tuned the bed heater and what PWM frequency are you using? Post your config.g
-
@trucker2215 it sounds to me that the PWM frequency you are using for the bed heater is too high.

@o_lampe I switch to bang bang and it went away Thank you guys so much for your help this was really annoying

@trucker2215 using bang-bang mode for a bed heater often results in Z banding. If you experience that then I suggest you try using a low PWM frequency instead.
