Is there a step by step on doing this?  Will the machine auto zero after removing the timing belts?  Still new to my devinci and i dont want to break it.  I have already dont a bunch of mods to print PLA successfully but i haven't had to disassemble the thing for that.

There is no timing, the zeroing as you call it is based on when the home X, Y, and Z sensors are tripped. You dont even need to remove the belts completely.  Just loosen the tension adjusters so you can slip them off the motor gears only.

Very loud, listen to this.

No dampeners, just properly tuned motors which you cannot do on a stock controller. The entire issue with a Da Vinci is the stock controller is putting too much current out to all the motors and eventually they will fail as mine did. Over driven motors are noisy.

I use the repetier firmware. I do not have anything to sound like yours?

So are you asking a question now? You already posted a video. You can use Repetier all you want, unless you use the dampeners yours will still be noisy? Only other option is to completely change out the controller to one that has current control on the drivers.

Loud printers are from the stock extruder being too top heavy and the brass bearings. If you put in linear bearings the printer gets pretty quiet. Not to mention ramps can tone down the Kyoto noise even more. Patching your extruder motors with ninja flex is useless. It's like putting saw dust in a broken engine.

You guys and your car similes lol, it makes me laugh. I agree the extuder is top heavy, that's why I swapped over to Andy's bowden extruder last year. These did quite my unit down quiet a bit, but are not an end all. They make a difference though and for people who are not as ambitious as you or I can benefit from them.

I can confirm this. Once I installed my RAMPS controller and adjusted the proper current to the motor I cant hear it making a sound from ten feet away. The cooling fan on the power supply is now the loudest part.

1. Jog the bed up to near top height and power off the machine.

2. Prop up the bed so it doesn't drop down. I used a paper towel tube.

3. Loosen the four hex nut set screws in the linking collar at the bottom of the threaded shaft. (They're really small, place in a safe spot.)

4. Hand-turn the shaft high enough to give some clearance to the top of the stepper.

5. Remove the stepper and separate from the mount.

6. Install the dampener and reinstall the stepper.

7. Hand-turn the shaft back down and align with the top of the stepper motor shaft.

8. Replace the linking collar, replace and retighten the hex nut set screws. Remove the item holding the bed up to height.

9. Test the bed for free movement by jogging down.

10. Power on and calibrate.

How's that look?

Edit: ...and this is exactly how I did it today

I installed three of the four dampeners yesterday while swapping out my bearing mounts.

I'm running my first print now and I must say that I'm pretty impressed. They make quite a difference, especially when your extruder is doing the zig-zag infill movement.

They are worth the effort of installing them for sure.

I will start that write up today too so you can get that last one installed. Thank you for the review!
