Dealing with some stepper driver adjustments I noticed a lot of high frequency vibrations on the x carriage. The heat sink fans add some vibrations but by them selves and lowering the speed a little I could learn to live with it. But when I fire up the radial nozzle fans 100% there is actually a lot of vibration. I do not know what this would do to the print quality but I bet it would give me a rougher finish. Anyways, none of these fans are very well balanced. So, is everyone using the stock fans? Kind of annoying they run at 24V. Makes finding replacements more difficult.
