      Hi everyone,

      I've converted my Elegoo Giga into a Duet-controlled machine and wondered if someone could help translate the start code that heats only the required beds (there are 4 x 400mm2) ,

      Here's my attempt, which at some point seems to override H0 (my heatbed 0) and in DWC where I have four heat beds, H0-H3, Heat bed 0 gets changed so I have two Heat Bed 1s.

      If anyone has any thoughts on how this could be modified to Duet appropriate code I'd appreciate it 🤙

      Thanks

        IF statements in RRF must be indented, so none of the statements you have will be working.

        https://docs.duet3d.com/User_manual/Reference/Gcode_meta_commands#conditional-construct

        It looks to me like to me IF statements are from a slicer START G-Code section.
        They may be workable there, but only the M140 commands should end up in your job g-code.
