UM2+ Power Surge? Video Attached.


Recommended Posts

Posted · UM2+ Power Surge? Video Attached.

Hey guys - I'm hoping someone can shed some light on an issue I'm having. The power seems to surge randomly during a print. The MeanWell 24v PS doesn't seem warmer than normal and I haven't clamped and tested voltage at all - just observation. 


I don't remember...are the fans on the head (hot end & print fans) 12 or 24v? 


Here's a video of the problem: 



Does anyone have any tips for diagnosis or is this a somewhat known issue that happens over time?


Any help is appreciated! Thank you!

    More information...


    I started a new print this morning and when the 'brown out' happens, the fan icon on the display disappears momentarily, then comes back on, off, on again and remains steadily on until the next 'surge event' happens.


    I've been running TinkerGnome's firmware for years with no problems...don't think that has anything to do with this issue.

    The fan icon blinks a few times when the requested fan output changes. But this is only related to received gcode commands, nothing else.

    As a first check I would search the gcode file for unexpected M106 commands.
