I am in the middle of building a replacement for the Black and Yellow Beast. I finished this machine less than a year ago but I made a number of improvements in the redesign and I am really happy with the way the BS1v2 (son of the beast) came out, so out with the old. This also gives me another chance to verify the design before I release it.
So anyways, I was over at cnczone.com soliciting recommendations for replacement screws and the subject of dampers came up. Having read cnczone for the last 3 years, I have seen dampers recommended a few times to help improve the speed at which a machine that uses stepper motors and lead screws can run, and although I thought my machine should be able to run faster, I never wanted to exert the effort to make a set.
This time was no different, but then a random thought crossed my mind about using pennies in place of the 1/2″ slugs (which have to be cut, hence the effort I was trying to avoid), and it didn’t seem like that much work after all.
So here is my “Penny Damper” design for your consideration.
There is a page on Inertial Dampers on the Solsyla site that explains the issue and shows several damper designs. And if you hunger for even more information be sure to search the cnczone forums for “dampers”.
Here is a link to a zip file of all the files I have for the Penny Damper, dxf, cut2d, and nc: http://grumpygeek.com/downloads/PennyDamper.zip
And finally, here is a not so short YouTube video:
These will be probably installed on the new machine unless I find they really are not needed, I am sure I will post about it when I get there.
