· UM2+ (fixed spacer) check with Air
Did some basic test with my air compressor and if it's too loose you can actually fell the air on the fingers (if you partially block the exit). So I don't think that this would work with an already assembled hotend unless you can actually put talc powder to be able to detect small parts of air moving there. At 50psi it was quite easy to spot the air, but much harder to stop the air from the other side.
Anyhow, I think the problem of hotends leaving gaps, it's that since the structure it's basically only supported by the alublock that goes in front of the fan, then it's quite easy to tilt the aluminium parts by doing too much pressure. So to actually be able to do the 'correct' pressure, you need to add the x4 long screws that pull the hanging parts of the top/bottom of the aluminium parts. I suppose a good trick could be to make pilars or some structure to actually be able to see when the excess of pressure it's actually bending the top/bottom.

Strap in for the first Cura release of 2024! This 5.7 beta release brings new material profiles as well as cloud printing for Method series printers, and introduces a powerful new way of sharing print settings using printer-agnostic project files! Also, if you want to download the cute dinosaur card holder featured below, it was specially designed for this release and can be found on Thingiverse!
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.
