      I have a D-bot 300x300 autobed level with bltouch
      How I can setup resurrect-prologue.g

      Could this be ok?
      M109 S180 ;preheat hot end preventing it to move the print form the bed
      G91
      G0 Z5
      M280 P3 S160 I1
      M280 P3 S10 I1
      G28 X Y
      G0 X35 Y-35
      G30

      It seems working but the temperature of HE remain at 180 even during print and I have manually to rise to the previous temp
      How can I obtain the right height to put in H param?

      Another question :
      I have a 2 x 24 power supply one reserved for bed, is technically possible to raise a bit hot end in case of power failure? Something light this will work?
      G91
      G1 Z5 F3000
      M83
      G1 E-5 F3000

      Last question:-)
      Would be possible insert on the power line a big capacitor for give some more juice during power failure procedures?

      thank you
      Andrea

        I have a bltouch also, but I don't use it in the resurrection macro. I home to z max endstop then continue if that makes sense. Hopefully that's what your after.
        I also had to use a UPS as I didn't have enough juice left to move up out of the way. I just used the battery on light through an optocoupler to an end stop and pause the print

          The temperature will be set before resurrect-prologue.g is called. You just need to do M116 in resurrect-prologue.g to wait for it to be reached, as https://duet3d.dozuki.com/Wiki/Setting_up_to_resume_a_print_after_a_power_failure#Section_Setting_up_the_sys_resurrect_prologue_g_file says.

          How can I obtain the right height to put in H param?

          Which H param are you referring to?

          You can connect a big capacitor across the PSU output terminals to provide an extra power reserve.

            Thank you for answering me.
            Regarding the h parameter maybe I saw , a different version of the wiki page. The one you pointed me is very clear. I seems to remember it would be possible to specify an H parameter in case the bed in the resume probe point has a different Z height but maybe I am wrong.

            In your opinion what specs the capacitor should have to fit the job?
            Thank you, very kind as usual.
            Regards
            Andrea

              I would try something like this https://uk.farnell.com/epcos/b41231a7229m000/cap-22000-f-35v-alu-elec-snap/dp/1839286.

              On a Cartesian or CoreXY printer, you can turn off the X and Y motors near the start of the power fail script, to conserve power for the E and Z motors.

                I'll make some tests to the gcode.
                regarding the capacitor could be a cheap idea for obtaining a little bit more juice .
                I can simply install it after the power supply no other component needed right?

                  That's right, just make sure you get the + and - terminals the right way round.
