Balancing the moving head

[akka69 0]

Hi,

I'm new to Ultimaker, but reading your documentation and watching your videos, i had this dumb idea.

Would the precision of the printer head moves be improved if you put a dead weight equal to or greater than the head's weight moving in the opposite direction?

Even if it increases the total moving weight and hence the motors effort, it would compensate the inertial reaction on the strutcure.

A little bit like counter rotating blades compensate torque on small model helicopters or rather those massive moving weight put on tall buildings to absorbe earthquakes moves.

Hi,

I have had the same idea, and I have made a counterweight system on the x-axis of my Prusa printer. I can't say if it helps, because I need to solve problems with the feeding mechanism before I can test at high speeds. It's also possible that acceleration have reduced the effect of vibrations so much already, that the counterweight is out of date...

The moving mass on my printer is about 160 grams, and I got a Bowden extruder as the Ultimaker.
