Repeatability, accuracy, and repeatability

Getting the machine to give me an accurate reading is one thing. Getting to do it after running code and rapids is another. Tuning stepper motors for those who don't know is a balance between steps/unit (mm for me), velocity (fastest the machine is to go), and acceleration (how fast it gets there). Just ordered some additional measuring tools to try to get the last bit of accuracy I need out of the machine to do parts I have designed. This is where the demand of accuracy and precession get time consuming and more then a bit nerve racking. The pay off when it is all done is going to be worth it but getting there can take a bit of time.
