 +  * 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.
 +  * 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.

 +===== USB Format =====
 +When loading G-code from a USB stick the Prusa 3d printers are only set up to support FAT32 file systems and the partition table should also be MBR.
 +If your USB stick works fine on a computer but isn't loaded by the printer, the most common issues are:
 +  * It's formatted as exFAT rather than FAT32
 +  * It's using a GUID partition table rather than MBR
 +
 +For full details on why and recommended formatting tools on different operating systems please see Prusa's article on the subject.

 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.  Abrasive filaments should not be used on this printer but can be used on tool 1 of the Prusa XL.

-===== Priming tower ===== 
- 
-The priming tower (not to be confused with the wipe tower produced by MMU2S/MMU3) is a small, mostly hollow block that is used to stabilize the pressure inside the nozzle once an extruder is unparked from the dock. 
-The printer extrudes a tiny amount of filament from the nozzle to stabilize the pressure inside the nozzle and then continues to print the main object. As a result, the priming tower is thin and light, resulting in minimal waste. The priming tower is supported with a hollow cone to ensure better stability. 
-The priming tower settings can be altered in the Print Settings -> Multiple  Extruders menu. 
-However, the default values work for the vast majority of prints and we recommend keeping them untouched. In case you're encountering stability issues, you may consider changing the Width of the tower or the Stabilization cone apex angle. 
- 
-Switching between extruders is nearly instantaneous and there is very little waste because the XL doesn’t require a full wipe tower or a bin for plastic waste. All that is needed is a compact priming tower design to stabilize the pressure inside the nozzle. You can further reduce the amount of wasted filament by employing smart features from our PrusaSlicer, such as wipe to infill, which allows you to prime the nozzle into the object’s infill.

-  * smooth -- this is the same as the previous printers. It should only be used for PLA. If you're printing ABS, PETG or FLEX, then you *need* to use the textured sheet. +  * satin -- this is the default sheet for all filaments 
-  * 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. +  * smooth -- 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.
-  * 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.+Any doubts check here: [[https://help.prusa3d.com/filament-material-guide|Filament Material Guide]]

-===== 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.+
