I do this in order to ensure that the filament has a smooth path from the extruder to the nozzle. There are a few dozen different extruders out there, so it’s hard to give a unique answer but here’s how I recommend doing this: Loosen the extruder idler tension to the minimum value My main reasoning when calibrating the extruder tension is to have a good enough grip on the filament so the gears don’t slip while keeping the deformation on the filament as low as possible. Over time, the gears can slip and filament can build up onto the gears.

I also recommend ensuring that the extruder gears are clean and free from plastic accumulation. To ensure an accurate calibration for the extruder (tension, e-steps, and flow rate) you need to ensure that the filament path is clear and the filament can move freely until it reaches the nozzle. Prerequisites for a successful extruder tension calibration In this case, the flow rate will also change depending on how much the shape of the filament changes. Instead of a nice round shape with a 1.75mm diameter, you can “deform” your filament into a saw-like squared piece of filament that has variable density across a specific length. When too much tension is applied to the filament, the extruder gears sink into the filament and actually crush it changing its diameter and shape. Unfortunately, we are not living in an ideal world so the diameter has a tolerance of about ☐.02mm to 0.05±. In an ideal world, the filament should be round with a 1.75mm diameter across the whole spool. The second factor that changes when adjusting the extruder tension is the filament shape. Of course, this change will be different between different types of extruders, gears, and hotends used. When the extruder tension is less than ideal, the gears can slip against the filament and the torque is not correctly transferred to it.

Usually, when more pressure against the filament is applied, there is more grip so the flow rate increases a bit. This change in flow occurs because the grip on the filament changes with the amount of tension applied by the idler or gear. Depending on the amount of tension applied to the filament, you will notice more filament or less filament flow through the hotend.

The first thing I notice when adjusting the extruder tension is the flow rate changing. When this happens, multiple factors change: Flow Rate When you adjust the extruder tension, you are basically changing the amount of pressure applied to the filament by the extruder gears.
