Upgrading the UM2 stock Hotend to a higher temperatur one
In this stable release, Cura 5.3 achieves yet another huge leap forward in 3D printing thanks to material interlocking! As well as introducing an expanded recommended print settings menu and lots of print quality improvements. Not to mention, a whole bunch of new printer profiles for non-UltiMaker printers!
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.
So the electric switch (mosfet) can handle up to 100 watts no problem. However the power brick will have trouble if you have the nozzle on full power and the bed on full power even for just 2 seconds the power brick may trip and shut down your printer long enough for it to reboot.
The solution is to install tinkerMarlin which has power management and will give the head priority if the overall draw of power exceeds 180 Watts.
3dsolex sells high quality heaters for UM2 up to 50W and they work just fine.
However if you need the bed at 100C (and nozzle at 240C) then you probably need to beef up the 24V supply or add a supplement heater: a second heater under the bed that does maybe half the heavy lifting and the remaining work is done by the existing heater/temp sensor solution.
Here's an old post about how the power budget works in tinkerMarlin - read this after you install it and have the new print head installed:
how to use tinkermarlin power budget
To me the power budget feature is very simple but it seems to confuse people. The power budget feature does not know how much power each element uses so you just tell it. Tell it how many watts everything is and what the budget is and it will make sure heaters are turned off or turned down a bit when they would exceed the budget. The bed gets lowest priority.
In this version of Marlin is a power budget system. Set the bed to 150W (that's what it's supposed to be I think) and set the nozzle to 25W (if you have 3rd party nozzle such as 3dsolex then set this to what is truth - what nozzle actually is).
Then if you set the budget to 175W (150+25) the power budget won't do anything and the printer will work normal. If you lower the budget to 150W then the power budget will lower the power to the bed when the nozzle is on. This changes many times per second (adjustments of power to nozzle). All the remaining power goes to the bed if the bed wants it.
So for example if you use 150bed/50noz/150budget nozzle is on at 50% (25 watts) then the bed will only be allowed 25 watts below budget (150-25 is 125 watts) and so the bed will never exceed 83% power at that time (83% duty cycle). This changes 20 times per second (nozzle asking for more then less power, bed occasionally restricted a little bit).

thanks for the reply. I think I will go for the option of installing the custom firmware.
