Heavy spindle problem !!!

[mindstorm88]

Hi guys ,

I've just completed the replacement of my old Porter cable router for a water cooled 2.2Kw spindle . It works great , BUT, i did not expect that it would be a lot more heavier for the z axis !! for now reducing the rapids on the z axis solved the missing steps . But would like to keep the speed i add. so

What i would like to know, is there any of you that setup something to counter weight a spindle, any idea?? , springs, bungee cords !!!

Thanks

springs work on the shopbots you just need to know how much you will need to balance you spindle.

You might think about mounting a gas spring on your Z axis. I've tried other things, but that seems like the best alternative.

The acceleration settings may simply solve your problem.

Tried ,but no luck , reducing the top speed did , because it is only happening with rapid move !!

I'm gonna try the spring way !!!

Just welded and installed a bracket to support the spring !! set it up for a zero weight spindle when my longest tool touch the table !!!

my Z axis is now flying as it never did before !!!! oh yeahhhhhhhhh
