Posted · Info about UM2 Hot End "Matchless" upgrade

I'm still new-to-the-hardware side of things.  I recently came across some material about an "upgrade" that was done to the UM2 by 3Dsolex that they claim increased heat transfer and speed by doing some various things, and more as an academic exercise in understanding the evoluation from the original UM2 hot ends to the current Olsen Block, I was wondering if anybody can explain what the deal is with the "Matchless" heat block and if it's totally depricated or has any performance benefits. 

 

From what I can piece together, it seems like their matchless nozzles are still things people use, but that maybe they just use them with the Olsen Block?

      • S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
        (Sorry, was out of office when this released)

        This update is for...
        All UltiMaker S series  
        New features
         
        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.

      • Ultimaker Cura 5.6 stable released
        Cura now supports Method series printers!
         
        A year after the merger of Ultimaker and MakerBotQQ, we have unlocked the ability for users of our Method series printers to slice files using UltiMaker Cura. As of this release, users can find profiles for our Method and Method XL printers, as well as material profiles for ABS-R, ABS-CF, and RapidRinse. Meaning it’s now possible to use either Cura or the existing cloud-slicing software CloudPrint when printing with these printers or materials
