USD10,000 equals 1 to 3 control repairs. A retrofit can be less than 10k and avoid current and further control repairs. A retrofit to replace a control that repair parts are unavailable for makes all kinds of sense. On one of my machines with a functioning control (year model 1998 and the control runs fine) I want to replace the control because upgrade features I want from the manufacturer cost in excess of USD20.000 for the software alone. On another machine (also 1998 and functioning) upgrades are NOT available because the OEM is no longer developing software for that model. A retrofit to a current OEM control with the desired capability is more than USD120,000. I have several three axis mills. I have several rotary tables. To marry the tables to the current controls will be more expensive than a retrofit. My retrofits are on the network for communication. The OEM controls are not. A LinuxCNC retrofit does not require all steppers or all servos or even all the components of either to be the same. ...etc ad nauseum :) What's not to like? The main gripe is the 'start from line'. I agree that could be 'enhanced' although my Fanuc controls are not much better at starting from a line if the program is long enough to need to run by DNC. Also, the Fanuc start from line doesn't start from a line in the middle of a tool without switching to MDI to make sure the prep codes are correct. Some of the other controls are much better at starting from a line. Having some fun now. Stuart
