Ive done a few cuts in aluminum. It seems like there is a lot less vibration throughout the machine. Id say it has had an impact on the chatter, not a huge one. I knew this mod had a diminishing effect on the 500mm version of the machine. I feel more confident cutting aluminum now, that’s for sure.
I did make the vacuum table. I made an alignment error when cutting the top, that’s why it looks a little screwed up. Ive hardly gotten to use it since I’m waiting for the silicon gasket from mcmaster. Heres a video I put together of the first test (caution loud).
