Othermill Origin and changing origin

[Mike6158]

I probably could have drilled a hole and filed it out to 17.5mm square on three panels with all of the time I've used on this software today. About 8 hours so far for a relatively small and simple operation (if you know what your'e doing, I don't).

I've attached the F3D (I think that's what it's called)

This is the part. It's a 2mm thick end cap for an extruded aluminum box. The only thing I need is the 17.5m square hole in the middle and the two screw holes (4mm) on either side. The plate comes with the 4 corner holes. 

I got to this point fairly quickly. You can see where I backed up and corrected some mistakes. The screenshot is before I fixed the last one. .frd file is current. Other than some depth issues with the Othermill (it was milling out the air above the stock when I first tried it) it cut the square hole fine. It did not cut the two round holes. I made some changes and now when the simulation runs it cuts all of the holes and I don't need it to do that. In both cases it cut the perimeter and I don't need it to do that. That's a rundown of the old problems that probably still exist. 

The new problem is where I located the part on the origin. The Othermill wants the origin to be the top of the top left corner with the Z axis up, X axis from left to right, and the Y axis forward. I can't figure out how to change the origin without starting over. Or maybe I don't need to change the origin since the test (on FR2) went fine with the exception of missing holes.

It's been a long day with not much to show for it...

The simulation indicated that the holes weren't going to be drilled but I decided that 11 hours of trying to use Fusion 360 had to produce something. So I sent the G-code to the Othermill and ended up with this:

 

I'll call it semi-success but I would like to know why the holes weren't drilled.

are you useing the other mill cam program to do the cam.

It would probably be a good idea to review the CAM module in Support & Learning

It looks like you used a 3d toolpath to machine a part that should be done with 2d toolpaths.  Here's a screencast showing how to do this part. 

Notes:

I just picked tools at random, you'll need to select the correct sizes.

I didn't do the perimeter, but it's just a contour operation. Remember to use tabs or other hold down method.

I used the CAM module in Fusion 360, exported the G-code, and then opened the G-code in OMC, set everything up, and ran the part. 1/8" end mill.

"It would probably be a good idea to review the CAM module in Support & Learning"

No doubt about that. I just winged it with a few setup steps from the Othermill site. I had never used the CAM module before yesterday (shows how good the software is... very...)

The holes in the part had length, width, and depth. That's why I chose 3D. That and the Othermill site recommended 3D Adaptive Clearing- "and is also a good first step if you don’t know what type of toolpath to choose." Raises hand... that's me... 

Tool - 1/8" flat end mill. I could have used an 1/8" ball end mill or one of the smaller (more fragile) end mills that I use on circuit boards

I'll watch the screencast. Maybe that will tell me why the holes didn't mill. 

Thank you
