Recommendations for Avoiding Clogs

• Keep your printer in a room with an ambient temperature of at most 25°C.

  

  We have successfully printed at much higher ambient temps, but the clog risk increases significantly.
• Use the Bambu Lab Cool Plate or keep the bed temperature at 55°C or below with PLA.
  
• You can often lower the nozzle temperature by 5-10 °C because of the different thermodynamics of the Mako Hot Block compared to the stock Bambu.
  
• This is especially recommended when printing detailed objects at slower speeds and lower flow-rates. 
• Ensure the filament is dry.
• For enclosed machines, print with the door & lid open.
  
• If you are using the AMS on your printer, you can try printing this Lid Lift Device from YelTrik Designs to have the lid open, without needing to relocate your AMS from the top of your printer.
  
• Bambu Studio Slicer Settings
  
• Make sure to use our custom material profiles for the Mako Hotend here.
• In the Bambu Studio Slicer, reduce the retraction length to 0.6 mm (Printer Settings > Extruder) & disable “Long Retraction When Cut” (Filament Settings > Setting Overrides). If you don’t see the “Long Retraction When Cut” setting, there’s no need to worry. It appears this setting is only available for certain versions of Bambu Studio and for specific printers.    
• Switching From High-Temp Materials to Low-Temp.
  
• If you just printed with a high-temp material and want to switch to a low-temp one, it is advisable to manually heat the nozzle to the higher material's melting point again and manually extrude some before trying to load the low-temp material. 
  
• For example, going from ASA to PLA: Heat the nozzle to 280 °C, push PLA into the top of the extruder, then manually extrude a few times. 
  
• If using the AMS to do this, ensure the nozzle temp is set to at least 250 °C when switching materials. 
  
• If the lower-temp material will not extrude using the AMS, it is likely not clogged but is being blocked by the higher-temp material still in the hot block after being cut. You will need to do the manual purging and loading process described above to load the PLA. 
• More in-depth information can be found in Bambu Lab's Recommendations for Clog Reduction. 

Important: After importing our custom material profiles into Bambu Studio, you must manually select them before each print. Bambu Studio does not apply imported profiles by default, so failing to select them may result in suboptimal performance or clogging.

If you do experience a clog, please follow these instructions to clear it. If the issue persists after making the changes listed above, please contact our Customer Support Team and we will make sure the issue is fixed.
