This is a common problem. It's almost always the power brick. If the brick senses that you used too much power it shuts off. But only for about 1/4 second and then power comes back on. This appears to be a plain old reboot but is really a power off/on very fast.
If this printer is less than a year old I would try to get a free one from your supplier. If not you can just buy the power brick.
Until you get the new brick you can avoid using the bed and instead use a cold bed and blue tape washed with isopropyl alcohol. Your printer should have come with blue tape for this purpose.
Alternatively you can use the power budget feature in tinker marlin which is a fantastic alternative firmware for um2+ extended. You can download it here (you want the 5th one down of course):
The UltiMaker S7 is built on the success of the UltiMaker S5 and its design decisions were heavily based on feedback from customers.
So what’s new?
The obvious change is the S7’s height. It now includes an integrated Air Manager. This filters the exhaust air of every print and also improves build temperature stability. To further enclose the build chamber the S7 only has one magnetically latched door.
The build stack has also been completely redesigned. A PEI-coated flexible steel build plate makes a big difference to productivity. Not only do you not need tools to pop a printed part off. But we also don’t recommend using or adhesion structures for UltiMaker materials (except PC, because...it’s PC). Along with that, 4 pins and 25 magnets make it easy to replace the flex plate perfectly – even with one hand.
The re-engineered print head has an inductive sensor which reduces noise when probing the build plate. This effectively makes it much harder to not achieve a perfect first layer, improving overall print success. We also reversed the front fan direction (fewer plastic hairs, less maintenance), made the print core door magnets stronger, and add a sensor that helps avoid flooding.
The UltiMaker S7 also includes quality of life improvements:
Reliable bed tilt compensation (no more thumbscrews) 2.4 and 5 GHz Wi-Fi A 1080p camera (mounted higher for a better view) Compatibility with 280+ Marketplace materials Compatibility with S5 project files (no reslicing needed) And a whole lot more
Curious to see the S7 in action?
We’re hosting a free tech demo on February 7.
It will be live and you can ask any questions to our CTO, Miguel Calvo.

Are you a fan of tree support, but dislike the removal process and the amount of filament it uses? Then we would like to invite you to try this special release of UltiMaker Cura. Brought to you by our special community contributor @thomasrahm
We generated a special version of Cura 5.2 called 5.3.0 Alpha + Xmas. The only changes we introduced compared to UltiMaker Cura 5.2.1 are those which are needed for the new supports. So keep in mind, this is not a sneak peek for Cura 5.3 (there are some really cool new features coming up) but a spotlight release highlighting this new version of tree supports.
Often getting started is the most difficult part of any process. A good start sets you up for success and saves you time and energy that could be spent elsewhere. That is why we have a onboarding course ready for
Ultimaker S5 Pro Bundle, Ultimaker S5, Ultimaker S3 Ultimaker 2+ Connect.
They're ready for you on the Ultimaker Academy platform. All you need to do to gain access is to register your product to gain free access.
Ready? Register your product here in just 60 seconds.

Go into power budget. I believe for normal printer you want:
budget 180W
bed 150W
nozzle 30W
With the above settings the budget will never limit power. so then you just lower the budget a bit:
budget 160W
bed 150W
nozzle 30W
That should be plenty to avoid tripping the power brick.
