Hello,
First, I'd like to thank all the developers of Gcodetools. I use it several times a week since I got a 3-axis mill for my job, 1 and a half year ago.
I noticed that Gcodetools does the drilling operations with a G01 move.
This is sometimes a problem, especially when drilling deep holes with a router bit : the spindle can easily slow down, or even stop !
There are special Gcodes for drilling like
G73 and
G83.
So I made a small modification on Gcodetools source code to allow the user to choose the Gcode to use on drilling.
It adds a choice of drilling strategy in the options tab.
Here are the patches :

Thanks again,

!
... just have no time... hope to find some soon, it's really needed to make a release of new version...
. I've patched dev version, so this enhance is available since rev. 241.
