| High power, low capacity UPS backup power? |

My 3D print was messed up by a one second long power outage. It was a small test piece, but I am planning larger things that will take days to print. So I'm looking into UPS battery backups. The occasional electrical outages I experience are just a blip; just long enough to reset the clock on the microwave. I hate to pay $160-200 for a large UPS knowing that it will degrade and become worthless over time. I also don't need the big storage capacity. I do need the large wattage rating though. Does anyone make a small (<$50) UPS that doesn't shrink the wattage along with the battery size? Is there some other cheap device that I might be able to get away with? I have the kill-a-watt knockoff out to see how much power the printer is actually drawing, but have to wait for the current print to finish. Also.....giving this some more thought....It wouldn't be that big of a deal if the 110v to the heated bed were cut for a second. The raspberry pi only needs a 5v dc backup and the SKR boards need 24v dc. EDIT: printer topped out at 541 watts while heating the bed to 110, heating the hotend to 200, & homing simultaneously. |

APC UPS 850VA runs $125 at Amazon. Replacement batteries $35. Anything in the range you want to spend isn't going to give you the watts you are seeking. |

Staples regularly has coupons to get a decent amount off if you spend more than I think 100 so check there first. Other than that I don't know how to help as UPS are just expensive. |

Does anybody here have a 3D printer that ---smurfing--- works? |
| BadMouth:
Thanks for the input. Gonna keep my eyes on slickdeals for a refurb. There was a big one for around $80 a couple months ago. Hopefully another comes up in that price range. --- Quote from: Mike A on June 28, 2021, 08:09:32 am ---Does anybody here have a 3D printer that ---smurfing--- works? --- End quote --- It's a horrible, time consuming hobby. |
