LOL, I understood what you were saying when you said “Be sure to jump positive to negative” when you were replacing the battery, but if someone isn’t paying attention to what you’re doing in the video, just jumping positive to negative of one battery could cause a problem. 😂
This might be a stupid question, but I tried connecting a smaller UPS and it was highly problematic. If I recall accurately, even with the two printers turned off, in the morning the batteries would be dead and the GFCI outlets tripped. I tried another UPS and the same thing happened with it. I tried printing with one connected and they would trip the outlets and run off of the battery till the battery was dead.
You are not supposed to run a printer on UPS alone. There should be a relay input that pauses the print and leave the bed only to save the UPS power and prevent print failure or frequency variations
It may depend on where you are but you can take them to battery scrapper. I think we got around $120 for the lead scrap cost per pound (it was a very large UPS and 4 car batteries $5 a piece core charge). I just did a lookup on lead prices and right now it is ~20 cent a pound which may not be worth the gas price to bother with. Anyway just a thought.
@@3DPrintedDebris usually runs between $.11-$.25/# for sealed lead acid batteries. Should amount to a pretty decent scrap run once you accumulate some.
Yes most people have no idea what a UPS is. Regardless of the power filtering and smoothing it's actually worth it for just power cuts as you can keep 3d printing and not lose your 24 hour print because of a 3 second power blip!! Also you are better of getting a couple of really big UPS's rather than loads of small ones, the small ones are generally crapper at power filtering etc. 2 x Eaton 5000va do me.
Part of the consideration is cost. The Eaton 5000VA is $4K+, whereas the equivalent KVA distributed across 3-4 Cyberpowers is under $1K. I also like distributing the failures across multiple members as each at most will run $200 to replace. I might start doing component level repairs on the mainboards in the UPS; it's all surface mount and it seems the voltage regulators are the most failure prone component.
@@3DPrintedDebris Makes sense - I need UPS's to be bombproof (not need surface mount components changing). I ran APC for over a decade but things started to go down hill there. Eaton are to UPS's what Prusa are to 3d printers I guess. It's the old cheap/reliability balance. :)
I need your opinion on an issue I am having and think a ups might be the answer. I print with overture pla right at the verge of getting a matte finish. I have 2 enders on the same power strip and today I noticed on one print I am getting what looks like heat streaks to what I can only think is that the stepper on the x axis is actually slowing down and causing the heat build up on a few layers on one side. Brand new thermistors mind you. I had both printers running when this occurred so I turned one off and attempted to print the same model on the same printer that had the issue and it seems the problem disappeared. I am thinking I am having some kind of power draw that is affecting the printers when both are running. Is this the kind of issues you witnessed that a ups helped clean up?? Thanks for your reply.
hi i have 4 printers 2 ender 3 ss1 and 2 elegoo neptune 2s the ender 3 s1 consume 350watts and the elegoo neptune 300 watts how many printers could I have connected at the same time with this ups
It's really just brand preference and familiarity. I'd say any UPS would suffice as long as the switch is fast enough and it has AVR. For now, I'm sticking with cyberpower as I have experience repairing them and they are a known quantity to me.
@@3DPrintedDebris thanks for the quick reply. I was looking at Amazon for the APC SineWave types and more than a few have had issues and fires. I have 19 machines and just want to make sure the power is clean and can cover a blip.
@@WhereNerdyisCool Just mind the wattage on warmup. I have 4 enders to 1 1500KVA UPS, and it overloads if I start more than 2 machines per shelf at a time. I've found 4 minis will run for 45 minutes on a 1500KVA with no chance of overload. You'll want to get one of these and map out your draws: amzn.to/3lSIY7X
@@3DPrintedDebris my intent is one ups per machine. A little more expensive but each machine is in its own enclosure with fire suppression and air filtration system
@@WhereNerdyisCool I've had one UPS short out and stink up the shop in 4 years and 24 UPS. It was my fault, back when I was using terminals for mains instead of sticking to UL plugs. One of the grounds worked loose, and crossed with the hot line taking out the UPS. OOps!
I restructured them since installing the 18KW standby generator. I used to run 2:1 to bridge through a 30 minute brownout. Now I only need 2-3 minutes while the generator spins up and I switch over to propane power. As a result, I can run 4 enders to 1 UPS, or 5 Minis, or 3 MK3S. With the 4 enders I can only warmup 2 at a time or I overload the UPS. It's easy enough to move the warmups around to work around the limitation.
@@3DPrintedDebris oh nice! So I think could run 2 printers using your dame UPS I guess. Btw, some people say it's not a good idea use an UPS with a 3d printers cause when the bed and nozzle are heating there is a consume spike and UPS and 3d printers can be damaged for ever. Do you have any idea? Cause u made some test and you say something similar in the video about UPS and 3d printers diying xD
@@atmatm1557 I see regular battery cell life maintenance, that's about it. I have to replace the batteries every 3 years. For my climate, that is expected. "The experienced man doesn't suffer the opinions of the inexperienced". And no, I've never lost a printer to an UPS issue, nor did I say that in my video.

Love your content and channel! Thank you for sharing your knowledge and experience with us.
Thanks for the encouragement! I have about 60 videos in mind, there's a lot rattling between my ears that I want to get out in video form.
Excellent. Thank you

Hello, with your experience for 3D printers what is the most reliable brand? THANKS.

Spectacular video
Thank you!
Just clicked on the link for the UPS and it took me to an air conditioner on Amazon. Thought you would like to know.
Thanks! I'll fix it.
@@3DPrintedDebris It just brought me to a loptop on Amazon.
The link is back to an air-conditioner. What the heck?

Given the low cost of UPS (as compared to 3D printers) you might as well buy a set and test it out.
hi i have 4 printers 2 ender 3 ss1 and 2 elegoo neptune 2s
the ender 3 s1 consume 350watts and the elegoo neptune 300 watts
how many printers could I have connected at the same time with this ups
Great question! Get a Kill-a-Watt meter and map out static, warmup, and running currents. These UPS don't like to go higher than 10A. Good luck!
I love your short in depth videos, but you didn't calculate the efficiency losses of the active filtering of the UPS
Oh I did, but those will be covered in my power video once I re-release it.
@@3DPrintedDebris awesome! If it's not finished yet, please mention your local electricity cost
Same ups I run.
They have served me well!
Hello. recommend me a cheap UPS that holds an anycubic mega s 3d printer. a thousand thanks
Other than the one I feature in this video?
@@3DPrintedDebris Thanks for the reply. I wanted a cheap UPS, nothing too professional. thanks 👍🤑
I noticed you're using CyberPower, does APC not offer anything as good? (Just curious!)

Hi! One question. Do you have 2 3d printers per UPS?

It's pronounced UPS, like the shipping company.
That's not the way I pronounce it.

ikr 😂 I'm confused at first
