When issue a M80 power on command, LCD need to do a initialization procedure to show characters on screen. is there a command to do this? or simply add a line to config.txt will do just fine? currently I have to reset system to get it going. then the host connection will be broken, and a reconnect will be needed which is quite troublesome. not yet look into smoothieware source code yet. try to look for a easy way to do it. Thanks for your help!
