I have a question about the file generated by using the digitizing wizard in Mach. When I open the file that's generated during my probe it only has a list of numbers like this:
1.487484,2.465796,6.346739
1.567484,2.402796,6.334739
1.387484,2.775796,6.395654
1.569484,2.465796,6.391239
These are not the exact numbers but this is the format stored in the file. I understand these are xyz coordinates generated during the probe but there are no G-M codes or feed rates, just numbers. Am I going to have to edit and put in my own codes or did I miss a step somewhere?

Put a check here, in Ports n pins / Mill options.

Thanks for the quick response. I'll be on the road for a few days so I won't get a chance to do that probably until the weekend.

You're very welcome.
Be sure to let us know how it goes.
Regards,

I'm just thinking out loud now and I'll get my answer sometime this weekend but... with the resulting gcode using the digitizing wizard, when I go to cut my material, will up be up, over, down, up, over, down like the probe or will it cut like a 2.5D?
-
Not up, over, dn ....point to point.
:)

Russ - doesn't your option just add in X,Y and Z i.e. it doesn't add in any G commands so in answer to IB's last question - neither?

Hi Ian, afaik, after setting up and running the wizard at it's specified feed rate, the file is created point to point as in the example shot.
Then you'd have to select a cutter and insert the associated settings for machining. Feedrates and such.
Only used it a couple of times.
Hope I'm understanding your question.

Hi Ian, here is the file created from the above illustration.
All I added is marked, it just rolls along point to point, not up/over/dn as when digitizing.

Thanks Russ, that's exactly what i was looking for. I only know enough gcode to send my tool deep into my table.

Thanks Russ. Just a thought Darryl - "normally" you'd take the wizard output file and use it in a CAD package to create a model of your original object. You'd then use CAD to produce a toolpath. If you want to skip these steps you need to cut with a ballnose that's pretty much the same size as your probe tip. Sorry if I'm stating the bl**ding obvious ;D

You're not stating the obvious to me. I'm new to all this. I built a probe and dying to try it out.
