· Hotend Heater and temperature sensor on a UM2
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.
Cura 5.7 is here and it brings a handy new workflow improvement when using Thingiverse and Cura together, as well as additional capabilities for Method series printers, and a powerful way of sharing print settings using new printer-agnostic project files! Read on to find out about all of these improvements and more.
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.
