You should add some limit switches (and I'm not just saying that because I sell a kit to do so.) Adding limit switches will greatly improve your workflow and allow you to recover if the machine crashes or you break a bit.garetbiglow wrote:All the USB stuff is super annoying. I have USB dropouts here and there (just wrecked a $40 piece of walnut yesterday) and it's really not predicatable. It's especially annoying when you run the machine without limit switches, as when the machine screws up, there is no way to recover your position smoothly.
