Bed Heating Issue



  • New installation of a Duet2 WiFi running firmware 3.0 on a Leapfrog Creatr HS which runs on 24v and has a 24v bed heater.
    Cannot get bed to heat by activating heat bed in Tools menu.
    Getting warning stating to long to heat.
    By using M303 bed will heat to 60c then I can activate bed heating in Tools menu and will then regulate heating as normal.
    Have run M303 several times with M501 at end of /sys/config.g
    Also tried PID and Bang Bang

    Thanks
