Mach3 Or Cambam Problem

[TomS]

Yesterday I ran a job and the mill worked fine. Today I started it up and my tool paths are mirror's of what is displayed on the screen.

This is the Cambam screenshot showing the tool path. If the image was flipped down that is the gcode tool path generated. Something has changed but I'm not sure what it is. I reviewed my configuration files/screenshots and and the settings are as they have been for weeks.

What do I need to change to get the correct tool path?

Thanks - Tom S.

First thing I would do is check the Gcode itself. it'll be very obvious if it's a post issue or mach3 from the code.

If it is mach3, check the "scale dro" on the main screen in Mach3. it should be set to 1.0 and not -1.0.

Possibly the Z direction of the coordinate system in the CAM?

Is it possible that there is a G68 or G69 (rotate work coordinates) lurking in there somewhere?

If you want to post your .cb or G-code file, I'll be happy to take a look at it. Change the extention to txt before posting.

I have never seen this problem before.

I checked the gcode and there is no G68 or G69 in there. I've attached the cb and gcode file. The first one is the cb file and the second one is the gcode file. Thanks for the help.

I took a look and I can't see where the Z direction is reversed. But that doesn't mean that I'm right. I seem to have a knack for having these odd problems with software. It could be me and not the programs.

The scale DRO is 1.0. I ran the gcode in Mach 3 and the tool path is correct on the screen. This is very strange.

Thanks for your comments though.

I can't see anything wrong with the cb file or your g-code. I'm gonna go with some setting in Mach3 but I can't help you there.

Thanks for looking. I didn't see anything either. My mill and Mach3 we're running as they should until I ran that Fusion 360/3D piece. I wouldn't think that would have any thing to do with it.

...............until I ran that Fusion 360/3D piece.

Ah ha! I'm guessing the HSM code changed something in Mach3. Have you rebooted the computer since you ran that code?
