Hi All..

Been out the loop for a couple of days but I note some fascinating posts from you cnc guru's.. Love the one about Mach and kernal speeds, have popped mine back down to 25KHz and it seems fine..

The sort of speeds you guys are talking about seem more than fanciful to me at the moment.. Have been running my machine at 1.8mts/min max during all these other problems, now that I can achieve more, I still dont dare go above 2.5mts/min due to the bent ballscrew shaking the machine so much.. I did try 4mts/min which the motors seem to easily achieve, but shaking was so severe I thought something was going to rattle off the machine.. Am going to try straightening the ballscrew today, will let you know how I get on..

Steve..
