New Autoleveling PCB software

[Dragonfly]

I know from my experience how vital is height probing and correction for milling good PCB's. I am using a Java program called PCBZCorrect which I found in the CNCZone forum. And since the source code is available I did some corrections by adding truncation and rounding functions to avoid errors like comparing 4.420 to 4.41999999999 which are practically the same coordinate but with a discrepancy due to floating point calculations. The interface is very basic and I was thinking about sitting down and making one like yours, Daedelus. Now I see you have implemented the idea.
I'll give a try to your program next time I make a PCB.
There are two questions I'd like to ask:
1. Does your program handle arc moves and especially long arcs where they must be divided into smaller ones to account for the Z changes? I am not using Eagle PCB and even though I can convert the arcs into straight segments I don't like the idea because the smooth movement becomes jerky.
2. Have you thought about such a scenario: a)There is a separate VB macro written for Mach3 to make the probing and save the results to a text file. b)Your program reads the probed values from that file, assigns them to Mach3 variables and modifies the G-code accordingly omitting the inclusion of the probing cycle. This way, even if one has to stop the milling for whatever reasons, it can be restarted successfully without losing the valuable height data. On a board with some tracks already milled you cannot repeat the process.
