What happens if retraction distance is too high?
Retraction Distance If set too high, the filament will be pulled too far back. Setting retraction distance too high is a problem because the filament can take a long time to start extruding again. It may also cause clogs. As a rule of thumb, don’t select a retraction distance greater than the length of your nozzle.
Can you have too much retraction?
Tuning your retraction is important because too much or too little will affect part quality. Too much retraction results in little gaps, or even globbing due to air pockets within the print head. When your printer does not retract enough, visible oozing will occur as the nozzle travels.
What should my retraction distance be?
According to the experts, the retraction distance should be between the 2mm to 7mm distance and should not be more than the length of the printing nozzle. The default retraction distance on Cura is 5mm.
What do you mean by retraction?
The Oxford English Dictionary (2018) defines retraction as “the action or fact of revoking or rescinding a decision, decree, etc.” A more thorough definition is, “the action of withdrawing a statement, accusation, etc., which is now admitted to be erroneous or unjustified… Identifying retracted articles.
Is it OK to retract an e3d-v6 Titan?
Usually we don’t advise retractions above 3mm, as this can result in jams (the molten plastic cools and sticks in the cold side/PTFE tube). With regards to the Titan clicking, it isn’t due to the gears slipping, but to play between the teeth.

How much retraction do I need for e3d-v6 nozzle?
If it works for you OK but be aware as low melt filaments like PLA can be a problem here. For the V6 nozzle assembly you should keep retraction to no more than 2mm as the heat break is quite short. If it works for you OK but be aware as low melt filaments like PLA can be a problem here.
How to get the best retraction length and speed settings?
It is the best technique to get the best suitable retraction settings. Print a small object just for retraction tests that can be printed in a short period. Start the printing process by changing the retraction speed and retraction distance step by step and see where the printer is performing well.
What’s the minimum amount of retraction you can do?
Once the travel speed is set, we’ll increase the retraction distance. Again, the goal is to use the minimum amount of retraction necessary. Using more than necessary can cause jams, blobs, and other extrusion related issues. This print has 1mm retraction with 150mm/s travel speed:
