Mini Kossel Delta Printer Sound Test ( Dry Run )

The video clip was recorded using my iphone, hand held very close to the mini kossel style printer I'm working on. The volume has not been reduced and is not muted.

Sound reduction parts/techniques employed:

Astrosyn Stepper Motor Vibration Dampers, Sorbothane Isolator Feet, and Delrin rollers for the carriages.

It is markedly quieter than the delta I built without the dampers.

In the video, the printer is performing a non-extrusion dry run printing of several vertical rectangular tubes. I wanted to give the printer a test drive before installing the extrusion and hot end bits. I was surprised by how quiet the setup was. The printer is sitting atop a medium weight wooden table. With past printers, it would act like a sounding board.

The vibration from the motors is greatly dampened by the astrosyn vibration dampers mounted between the stepper motors and the plastic printed frame. What little vibration that gets through doesn't get past the vibration isolation feet.

The vibration of the carbon fiber tube arms is reduced using dampers I made with left over GT2 belts and zip ties.

Any sounds that might originate from the carriages moving up and down the vertical HFS3-1515 extrusions is reduced thanks to the delrin rollers. The old bathroom sliding door nylon rollers tended to create a static/sticking sound.

The control board is the Printrboard(scavanged from my original PrintrBot Simple V2). The firmware being run is a custom Marlin derived firmware. Power supply is a 450W ANTEC PC power supply.

That is an awesome looking and amazingly silent build!

Got the astrosyn dampers, and they work wonders :) What thickness and level of softness did you use for your sorbothane feet?

Any secrets on getting it so quiet? Mine isn't running nearly as smoothly... the only thing I could think of is replacing the linear carriages since my friend printed them and they were warped (don't quite fit the rails correctly)
