Backlash Compensation

Is there any provisions for backlash compensation in the SB control software?

No there isn't. It really isn't a good idea either and falls under the category of, "You can't fix hardware problems with software." But that doesn't stop people from trying.

I did a bunch of reading on it last night. What I was able to figure out from a few forums is to get your machine right. Then try and pick up a few more thousands by backlash compensation. But you think is not a great solution either way? It seems to be pretty widely used and accepted. I'm with you though...seem kind of like a giant band-aid. I was just thinking if I could dial it in it might help pick up .003-.005" in tolerance. Just something to play with if it were available. Thanks as always for your hard earned insight.

"backlash compensation" - I don't think so! There are some great posts on here discussing keeping things properly tuned and replacing worn parts (IE pinions etc). I had an instance awhile back with some china end mills that were not cutting to my liking and what I discovered was a lot of 'bit flex'. Symptoms were similar to what I would expect from backlash but turned out it was in the bit itself. My machine is over 10 years old and I cut mostly cheap HD ply, so it gets a lot of long run use. The replaceable parts are cheap, quick to change, make my machine a good wood working tool. Russ
