 **Standard settings:** 1st colour, 2nd supports. These can be modified in the settings. You can use different types of filament within reason but consider the heat of the bed.
 Always make sure the filament in each line matches that in the software.
+===== Etiquette =====
+Only two 3D printers should be used by a member at any one time. If it is especially busy consider using one to be considerate of others.
 ===== Manual =====

+===== Filament =====
+All Hackspace 3D printers use 1.75mm filament. Most filaments such as PLA, ABS, PETG, FLEX etc are supported. Do not use filaments that require a nozzle temperature above 285°C such as polycarbonate.
+Abrasive filaments can be used on toolhead 1 as it has an ObXidian nozzle, but printing them on any other toolhead will wear down and break the brass nozzles. 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.
 ===== Inserting filament =====
@@ Line 33: / Line 43: @@
 Before you insert the filament, start by placing the filament spool on the side holder. Be careful not
 to let go of the end of the filament strand - the spool could easily tangle up.
+If there is filament already in the lines please remove following the removing filament guidance below.
   - Cut the end of the filament into a sharp point. Insert the filament into the PTFE tube on the side and keep pushing it inside. If the filament sensor is on, the filament will be automatically fed. If the filament sensor is off, proceed to step 2.

 ===== Removing filament =====
-**After use:** **Please completely remove your filaments** from all of the lines rather than leaving a clipped amount in. Due to the PTFE lines this would be significant loss and potential pain of the filament it used by accident and then cannot be remove from the tube.

+  - Select LCD Menu - Filament - Unload Filament
+  - The printer will preheat automatically depending on the selected material. As soon as it reaches the right temperature, the filament will be unloaded from the extruder in a few seconds.
+  - Once the extruder stops unloading the filament, remove it from the PTFE tube by hand. Please keep in mind that the process of unloading the filament strand from the extruder takes a few seconds. Do not pull hard on the filament when the unloading process is running. Check the printer's screen for information.
+  - Make sure to secure the unloaded filament when you wind it up back onto the spool. If the end of the filament slips out, the spool may become tangled.

 ===== Priming tower =====

   * textured -- this is the strongest sheet and is a good choice for general printing in almost any filament. It has slightly lower bed adhesion than smooth when printing PLA, but only slightly. Remember -- you may also need glue stick when using sticky filaments.
   * satin -- this is for PLA only and gives a slightly different surface finish.
+Toolhead 1 is equipped with a 0.4 mm ObXidian nozzle, allowing it to print with abrasive materials such as CF/GF filled filaments. **DO NOT PRINT THESE WITH OTHER NOZZLES, ONLY TOOLHEAD 1.** It will work with all other filaments on the approved list as well and should be all around more durable than the other nozzles.

+===== Common Problems =====
+==== Tool Offsets ====
+The tools can get slightly out of line with each other. This can be particularly noticeable on the z axis -- when multi material printing, you might find that one tool prints slightly higher or lower than the others. If this happens, you can re-run the tool offset calibration wizard: https://help.prusa3d.com/guide/4-first-run_468832#469249
+==== Bed adhesion ====
+As the printer isn't enclosed, it's prone to getting dust on the bed, and as it's a bigger bed anyway, it takes more cleaning. You might find that it takes noticeably more time to fully clean the bed. If you're having problems with bed adhesion, make sure it's very thoroughly cleaned.
