Extrusion rate smoothing (ERS), also known as pressure equalizer in Prusa Slicer, aims to limit the rate of extrusion volume change to be below a user set threshold (the ERS value). It aims to assist the printer firmware internal motion planners, pressure advance in achieving the desired nozzle flow and reducing deviations against the ideal flow.

Re: MK3 extruder randomly skipping. Print speed is now 70 mm/s(is fast i think), try 50 mm/s or 40 mm/s.(50 mm/s is standard in slicer). With infill speed of prusa with of 180 or 200 mm/s, i had the same issue Make this 100 mm/s. With big flat parts infill, the prusa could not do the job.

RE: My MK3S+ Extruder motor keeps skipping backward and clicking. Here's the E3D instruction: Screw in the nozzle all the way into the heater block. Don't worry about tightness yet. Then, unscrew the nozzle a full turn. This will leave a little space to tighten after screwing in the heat break. Here's the MH instruction:

Method 2: Pull out filament with pliers. While hotend is heated to 280° C, firmly grab the filament with the needle-nose pliers that came with the printer. Slowly drag/feed the filament upwards, bit by bit, through the top of the extruder body, until it is completely removed from the PTFE-tube. The filament can get stuck on geometry on the ...

Extruder clicking. The hotend or the nozzle is partially or fully clogged and the internal resistance against the flow of the filament is greater than what the gears are able to push. As a result, the gears are skipping leading to the "clicking" noise and in most scenarios also to the grinding of the filament. How to fix the clogged printer?

Step 9 Removing the extruder motor. ⬢ Hold the extruder in your hand. ⬢ Release and remove the lower screw. ⬢ Carefully place the extruder on a piece of cloth on the heatbed so that the motor faces down. If the extruder does not reach to the heatbed, move the Z-axis down or the X-axis closer. Do it manually, no need to turn the printer on.

Skipping Extruder. My printer is a MK3S+ with over 27 days of and Im very pleased with the kit. Suddenly my prints are ruined by a clicking sound in the extruder which causes large gaps on flat surfaces almost rhythmically. Here's what Ive troubleshot. 1. Cleaned nozzles and even with a new nozzle.

Too little or too much tension on the extruder idler spring can also cause issues with filament extrusion. With the idler screw being too loose, the gears can't grip the filament and the motor can start skipping. With the …
DetailsThe retraction was in fact the filament slipping on the extruder gears. Best way to diagnose this problem: unload the filament and reload it. If the extruder clicks during loading and too little filament is exiting the nozzle it is a partial clog. Keep replacements nozzle on hand, they are not very expensive. Thanks for the help.

RE: Extruder clicking when loading filament, leads to filament grinding.

6. Run the procedure described in STEP 1. You should be able to run the extruder with at least F450-F500 speeds. I was able to run with F800 with no clicking. 7. If confirmed that this is in fact the extruder motor replace it witw a new motor. Put the X-axis motor back in place and order a new extruder motor from Prusa shop.

Use Setting > Move Axis > Extruder to extrude some material out (rotate knob towards higher values, i believe) and check if you see consistent filament movement and extrusion; If you don't see extrusion, open the idler door and inspect the pulleys, look for signs of dust that may indicate filament degradation.

Make sure the filament end is straight and has a sharp tip at the end. Reattach the PTFE tube and hit Retry. Inspect the extruder to rule out a hardware fault such as misaligned Bondtech gears or Extruder Idler shaft not inserted correctly. In case the issue continues to happen over multiple unloads, check the extruder for clogging.

MK3S+ prints for approximately 1 hour then jams and stops . After about 45 minutes, I begin to hear intermittent extruder clicking noises. After the part stops , I shut down the machine and attempt to remove the filament. It becomes stuck in the PTFE tube and I can only remove it if I heat the nozzle to 270 and then pull it out.

The extruder stepper motor sometimes makes a CLUNK sound and doesn't appear to extrude the right amount of filament. It seems like something inside the stepper motor is slipping.

Saw this somewhere: I opened the extruder, loosened the servo screws and re-tightened it after pushing the motor towards the pinion: before it was a click-click noise, now it is a gentle humm.

Lift z: lifts the extruder during movement. Having this setting lower will improve stringing. Note that disabling this feature may cause the nozzle to hit the printed part. Retraction Speed: Extruder motor speed on retraction. A higher value improves stringing, but if it is too high it may skip steps in the motor.
