 ====== Ultimaker 2 ======
+**N.B.** This printer normally has a glass build plate. The instructions below are for this. River is experimenting with a PEI plate, which you might find installed. If unsure please ask River or Miron, and avoid damaging the plate.
 We bought an Ultimaker 2 3D printer in December 2014. Thanks to all those who [[3dprinterpledges|helped fund it]].

-The printer can operate using PLA or ABS filament, with a 2.85mm diameter (sometimes sold as 3mm). PLA is preferred as it is cleaner to work with. If you wish to print with ABS then additional ventilation will be required to deal with styrene fumes.
+The printer can operate using all the normal filament types, with a 2.85mm diameter (sometimes sold as 3mm). If you wish to print with ABS then additional ventilation will be required to deal with styrene fumes. Better use the Voron which has some filtering. Abrasive filaments are also a job for the Voron, because it has a hard nozzle possibility.
-NinjaFlex (a flexible plastic) may also be used. [Question: Does this produce fumes?]
-We may wish to restrict printing to materials supplied by Hacklab to ensure that cheaper or inappropriate materials do not damage the printer. If someone wished to purchase their own filament for a larger project we could allow this as long as we can check the material in advance.

+===== Slicers =====
-Download the Cura software from: http://software.ultimaker.com/
+Cura is the standard one for this printer, but you can also prusa slicer, which I think most people prefer. You need to be a bit careful with it though because it doesn't properly allow for the clips that hold the bed on. Keep parts away from the corners, and especially watch for prusa slicer adding brims in these areas.
 **Try not to let Cura update the firmware on the printer to the official one, as the upgraded extruder requires TinkerGnome.** See below if this happens.

 Due to the improved extruder, this printer has been upgraded to TinkerGnome Marlin. If cura has updated the firmware to the official UM2 release, you'll have to reinstall TinkerGnome from https://github.com/TinkerGnome/Ultimaker2Marlin/releases.

     - Once the print is finished, wait for the printer to cool down and say it's okay to remove the part. You can remove it earlier, but you risk deforming the printed part or burning yourself on all the hot bits.
