   * Do not touch the nozzle or heatbed when the printer is printing or warming up. The nozzle can reach 300°C and the heatbed can reach over 100°C.
   * Supervise at least the first few layers of the print and notify on the forum in the "long 3D print notifications" chat if you are going to leave the printer unattended for a significant amount of time.
-  * Report problems on the forum as soon as they arise. Do not attempt to disassemble the 3D printers unless you have been authorised to do so.
+  * Report problems on the forum as soon as they arise. Do not attempt to disassemble the 3D printers unless you have been authorised to do so. The nozzles cannot be unscrewed without disassembly, please do not try.
-  * ABS, ASA, HIPS, PA filament should not be used without additional advanced filtration system - the bench top ikea filtration is not suitable. Please speak to committee well in advanced if this is something you are looking to use.
+  * Do not try and swap the nozzles without mentioning on the forum and looking up a specific guide on how to do so.
+  * Before using ABS, ASA, HIPS, or PA filament make sure the top vent is closed and the chamber fans are running.
 ===== Induction =====
-Inductions for the 3D printers are now available on the member portal (PC near the door in the laser cutter room). Tap your card/keyfob on the reader, select “Manage machine inductions”, and take the 3D printer quiz. You will then have access on the RFID lockout box, you just need to tap your card/fob and it will switch on.

 ===== Filament =====
-All Hackspace 3D printers use 1.75mm filament. Most filaments such as PLA, PETG, FLEX etc are supported. Do not use filaments that require a nozzle temperature above 285°C such as polycarbonate.

-Abrasive filaments should not be used on this printer but can be used on tool 1 of the Prusa XL. Examples of abrasive filaments are CF / GF filaments, wood and metal filaments, and glow in the dark filaments. Please also structure your multi-material prints to avoid printing with the brass nozzles on top of an abrasive filament.
-Please **DO NOT** use ABS, ASA, HIPS, PA filaments as we need an advanced filtration system, please let committee know well in advanced if you will need this as a proposal will need to be raised.

 ===== Inserting filament =====
@@ Line 66: / Line 66: @@
 If you are starting with the printer, we recommend choosing PLA for the initial print. This material is easy to work with and does not require complex pre-print preparation.
   * Prepare a spool of filament (PLA is recommended), place it on the spoolholder on the side of the printer, and unhook the filament end carefully to avoid tangling.
-  * Cut the filament to a sharp point and push it through the PTFE tube all the way to the  Nextruder. Once it reaches the filament sensor in the print head, the loading process will begin  automatically.

   * When the Preheat menu appears, select the filament material and wait for the nozzle to reach the desired temperature. Once it heats up fully, it will push out a bit of material from the nozzle.

 Please open the top slide vent when using PLA.
+If you are printing with a soft or flexible filament, it might be easier to disable the filament switch.
+On the right hand side of the inside of the printer, where the filament comes in there is an orange switch. When that is set to X the filament path bypasses the switch and allows for easier loading and extruding.
+Please remember to turn that back on when finished, or if you notice it is off when not printing soft filaments.

+Similarly to the Prusa XL is that it's very easy to print on different steel sheets. We have several:
+  * satin powder-coated -- this is the default sheet for all filaments
+  * smooth PEI -- this is the same as the previous printers. It should only be used for PLA. If you're printing PETG or FLEX, then you *need* to use the satin sheet.
+  * textured powder-coated  -- rougher texture grips better to flexible materials, but also imparts a textured finish to the bottom of parts printed on it.

+The Core Ones are also fitted with High Flow ObXidian abrasion resistant nozzles and the Advanced Chamber Filters, allowing for abrasive filaments and filaments with gas byproducts to be printed. These are indicated on the material guide.
