R2 Click and Snapping Sounds

Hello,

I am having some odd clicks and snapping sounds coming from the printer. Here are some videos





Do I need to tighten something or is it broken?

 

Videos not visible, maybe private.

It's normal to hear clicks especially on the Z axis, that's from the balls falling onto each other in the linear bearings.

 

Fixed it Sorry about that it's on the X/Y Axis not the Z

 

See that's the really odd thing it only seems to happen while printing. I used the motor controls to try and do it myself it's whisper quite. I will take another look however in a few hours when it finishes.

 

I take it theirs no good manual for disassembly is there?

 

I've had a similar click (not all the time) on my R2. Turned out to be the extruder while retracting.

That may be why you don't hear the noise when moving the axis via the LCD controls.

While printing, take a close look at the shaft on the extruder and see if it quickly reverses direction when you hear the click.

 

So I was finally able to get it to reproduce the click. It requires me to go all the way from Zero to max on the X Axis. It clicks on any Y axis. and it will only creak on the positive X swing. I have investigated all the motors and gantry nothing seems out of place.

I squared it the best that I could but it still creaks at 124 MM every time.

 

Just for fun, unplug the cable from the top of the extruder and also remove the filament. Then re-test. Because I swear I was also getting some clicks that sounding like the cable was binding at a certain spot. I have not tried this and of course this assumes the printer will not error out with the cable removed.

 

Thanks Ed,

I tried all that and it did nothing vibration wise it seems like it's like the snap inside case..

 

Loose bearing maybe? I've never taken my printer apart, but thought I read on this forum that someone had taken their top frame assembly off. Here's a photo from the assembly line.

 

I kinda don't want to risk that I could damage the printer more. I will send an email to support.

 

I don't blame you Please report back on what they recommend.

 

Just got a similar noise... tangled filament on spool completely blocking supply and causing the extruder teeth to click on the filament's grooves.

 

Yea I don't think this actually anything on the extruder, Even with the filament entirely clear it still makes those noises Great you were able to fix yours though!

 

So I spent a good day disassembling the entire extruder assembly. Oiled it put it back together. After sacrificing a few goats it's up and printing again!

I thought I was in the clear but it still clicks I will let you know what support decides to do with it.

 

My R2 extruder has clicked noticeably on occasion if the bed Z offset calibration is not correct. If the first layer positions the nozzle too close to the bed, back pressure will make the extruder click.
