Hotend Heater and temperature sensor on a UM2

Posted · Hotend Heater and temperature sensor on a UM2

Hello everybody.

I wanted to know if any of you who mounted the Olsson BLOCK V3 MATCHLESS of 3dsolex left the old temperature sensor and the old hotend Heater 25 Watt and is fine.

Or it has replaced these two parts or one of them.

    You only need to replace the temp sensor if you cannot get the old one out in one piece.

    there is sometimes a bonding between the cartridge og the tempe sensor and the olsson block, or if there has been a plastic leak (before) where the plastic has entered the block and has glued itself to the temp sensor.

    If you have an UM2, the heater is rated at 25W. Sometimes they have less. You can OHM it with an ohm-meter. Should read 25 ohm or less. more than 25 ohm = less than 25 watt.

    The heaters are very good quality and rarly need replacement. The 25 W heater will give you trouble of you print at high temperature (220-225+) and suddenly the fans come full on.

    The Temp sensors from UM are also good quality, but by the nature of their construction they are more fragile; tiny little leads and a microscopic platinum sensor inside make them more easy to break, unfortunately.

    It can be useful to tell cura to put the fans on gradually and early. check in expert settings.

    A higher wattage heater, like the one standard in UM2+ will be able to withstand a sudden fan increase better or every time.

    The Um2+ upgrade kit from UM has the 35W heater and will annule any fan-suddenly-on problems.

    The Heater is allmost always easy to remove from an old block to put into a new one, because it sticks out a bit and can be grabbed by an instrument to be pulled out.

      • UltiMaker Cura 5.3 stable released
        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!

      • Here it is. The new UltiMaker S7
        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.

      • UltiMaker Cura Alpha 🎄 Tree Support Spotlight 🎄
        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.
