I am looking for a python script that will allow me to drill multiple random holes. I know nothing about writing my own script, but am not against trying to learn or modify one to work for me. Thank you in advance for anyone that can get me pointed in the right direction.

Wants:
1. Inch or metric
2. work coordinate offset
3. Feed rate
4. Plunge rate
5. Depth of drill
6. multiple X/Y coordinates
7. retract height
8. peck drilling option
9. coolant/vac start option

Probably poor choice of words. I would like to enter my drill locations.
Thanks

Have you looked at NGCGUI or NativeCAM (formerly known as Features)?

Might be a reasonable starting point. It's an embedded tab that performs simple repetitive motions.

In your case you would set it up to use a peck-drilling cycle.
linuxcnc.org/docs/2.7/html/gcode/g-code.html#gcode:g80-g89

Or, you could just use a peck-drilling cycle. This G-code is not much more difficult that write than filling out a table.

Thank you, I will look into the suggestions. I understand it that it is simple to hand code this, but I am looking for something that an operator (one that only knows enough to push the start button) could do.

I have a "almost" finished program that reads data from a dxf file and generates the holes code.

maybe with minor changes it can be suitable for you.

Looks interesting. How hard is it to modify for someone not knowing anything about scripting?

It can be challenging if you don't know nothing about programming...

I'm up for a challenge, if you are willing to share. Thanks
