Has anybody got the g-code for a spiral so i can make video of my mill strutting its stuff ;-)

Sure, what diameter do want and how many turns would you like? :wave: :cheers:

Here this is a quicky. 1/2 inch diameter, 3 turns, and 1/2 inch deep. You can input the beginning and end to your liking.

By the way, there is a thread on the site about a VB6 program for creating spirals in gcode. Has a good interface to enter your criteria and see the program draw the result to the screen, and the gcode.

Here is the thread: http://www.cnczone.com/forums/showthread.php?t=13277&highlight=spiro

Very long read, however, at the last page is the fully finished product as freeware. Very cool.
