Hi Tom, I had to machine some holes in a big piece of pipe a few days ago. Weight was about 1000 lbs and it really messed up the tuning in my 4th axis. Started to oscillate a little if I moved it at any speed. Didnt alarm out, I guess my following error is not set properly for that axis. I should look into that too I guess.

It was only an indexing job and managed to get it done by simply moving super slow to each postion. Is there any quick fix I could do to my tuning to make it more stable on larger jobs like this? What would be best guess? Maybe cut gains in half or something? More D gain? What do you think?
