Not Much Power Reserve on Power Failure
-
Hi all,
I have a question regarding the "recovery mode" after a power outage.
I use a Meanwell RSP 500w 24v power supply to power my prusa printer. I followed the documentation to set up this feature in the firmware.
My problem is that when the actual power outage occurs, the z axis does not lift and the extruder does not retract.
It seems that I have not much "power reserve".
How could I do to overcame this? Using an ups, as suggested by others, does not seem to be a good choice since the Duet would not see the power failure anyway.Thanks for your help

Yeah the ups would help only by letting the printer run long enough that hopefully the main power was restored. The ups may need to be rather large to get decent run time if using a heated bed.
The gantry on the z axis may be a bit too heavy for the remaining power to lift successfully. You can try adding some capacitors to the PSU. But I'm not an expert on what type to use or how to install them. You may be able to find the answer by searching the forum though.
