I bought a cheap Anet A8 the other day which is ok but print quality no where near as good as the robox, plus it doesnt have autobed levelling so that is a bit of a faff. However, it struck me how quiet it is in operation compared to the Robox. @17bt saw/ heard this the other day.
I narrowed down a lot of the noise in the Robox to the X carriage motion (and yes it level). So using the M503 command I change the motor drive current for the X axis from 1.124 Amps to 1.5 Amps. by typing M906 X1.50
Combined with reducing the accelertation value to 8 or even 16 as @17bt found and its significantly quieter. I might try it on the Y axis too.
Aerospace Engineer with a creative itch being scratched by Robox!
@chazr33gtr & others Robox noise is one of my pet hates, and I believe another forum member (@dave123 ?) replaced his steel linear bearings with IGUS equivalents, and they are significantly quieter.

There is something odd going on with the X rail, as you can feel the vibration when you slide it. Maybe the belt and pulley profiles could be improved, but some of it is the surface roughness of the steel bar for sure, and that’s why I like linear rails, which the BCN3D Sigma and the CETUS3D use for example.
When I dropped the acceleration rate down, it did make a difference to the noise levels, and hardly altered the time taken to print, but I’ll try the current increase later today and see what happens here. 🙂
How loud is the Robox Pro?
Hi colleagues.
My Robox make loud noise when printing models with support.
It’s such annoying noise that I can’t stand near printer long time. I found that it’s because of vibrations on door and back cover. But why that happening when printing support, I can’t understand.
May be you can advise something.
Best regards Aleksey.
I found that it’s because of vibrations on door and back cover
Totally agree @aleksey the door & back does vibrate, which amplifies the noise. Some desks or tables do too, so I found placing the Robox on a rubber mat helped.
Is support printing a faster speed? so this would make more noise??
@aleksey Support is printed at 35 mm/s which is faster than the rest of the print. If you create a new profile you can reduce the speed of the support printing which will reduce or eliminate the additional vibration. 35 mm/s seems to activate the resonant frequency of the steel sheets used for the base and the back of the printer.
I operate two Betas and four Production Robox.
I am the US/Canada Technical Support engineer for the Robox.
See my 3D Hub site at https://www.3dhubs.com/phoenix/hubs/benHi colleagues.
Just discovered that support printing speed 40mm/s.
So Hudson please advise which speed will be better for that?
