Installed the board went so easy not sure why but when printing the travel of y the motor would growl, I checked bed,belts only way to stop it was to disable stealth mode for y axis. Note I left current at default 600 no issues after doing this just wanted to share and see if this was the correct resolution
Sorry Tim it's the EZboard lite
Try upping the motor current. Thats quite a large bed. It may need a little more.
I increased it to 950 does the same noise growling it sounds like binding but everything is smooth only makes this noise and vibration when enabled stealth mode
