Recently I have been doing more carvings and less panel cutting. I am looking at upgrading my bot to deal with the chatter caused by short, jerky movements. The three options I am looking at are linear rails, Shopbot's Z axis upgrade, and motor change. If anyone has made any of these changes and could relate the pros and cons I would be grateful. I am not looking at selling and buying a new machine because I like tinkering with my bot.
