resurrect setting up help needed....+other issues..
mpoly last edited by
Hello and thanks in advance for any help knowledgeable people around here can offer..
I have a DuetWifi big Delta running on 24v 250w psu, powered by a 450W BRAND NEW UPS, no heatbed, nema17 motors, smart effector and volcano with 0.6 nozzle.
I have 2 serious problems (as I am mostly running over 10h prints on it)
The first is that i constantly get pauses on my prints with "Resume-after-power-fail state saved" messages on the console, which basically ruin my prints (large lithophanes and every time i resume i get a lovely horizontal line on the print that you can see from miles away) . The strange thing is i get them even though i dont have any other signs of power surges in the building (lights dimming or trembling). Maybe its a bad UPS, i cannot rule that out, but i dont know how to check this. I also have a 60watt dc cob led with a step up regulator on it for lighting the printer, running from the same psu. I have tried with and without it turned on, makes no difference.
The second very important problem is that i really dont understand how to setup and use the resurrect function.
here is my config file

I tried having both sd cards on the set (not sure if the paneldue one was needed for this but have one in the slot anyway).
Can somebody please explain step by step what i need to do to resume print after a powerfail? Am I supposed to find a sys/resurrect-prologue.g file on either sd card and print it? (there never is such a file after a powerfail). Or should i use the M916 command somehow?(tried but keep getting that there is "no sys/resurrect-prologue.g found" message
Have you seen? https://duet3d.dozuki.com/Wiki/Setting_up_to_resume_a_print_after_a_power_failure
It sounds like you have a PSU issue. I'm not an expert on troubleshooting that. sorry.

@mpoly, it sounds to me that either your power supply output voltage is too close to the 22.5V threshold you have set in your M911 command; or you have a bad connection between the PSU and the Duet; or the 250W power supply rating is marginal for your machine. So here are some thing to check:
Temporarily reduce the power fail threshold (S parameter) to a lower value, e.g. 20V (S20 instead of S22.5). Then run a CNC job. Then run M122 and see what minimum and maximum recorded voltages it reports. Note, running M122 resets the minimum/maximum recorded voltages after reporting them, so only the first M122 report after running a job gives useful values.
Check that the VIN terminal block screws on the Duet are tight.
Are you powering anything from the 250W PSU apart from the Duet (and hence the stepper motors)? As a CNC machine doesn't have heaters, I think a 250W PSU should be adequate unless you are powering additional devices from it, such as a spindle motor.
