I really hate to admit that I can’t figure this out, but every time that I try to set a machining region on a job it zooms the model to fit the window and seemingly disabled my ability to zoom in and out. Out of sheer luck I got MeshCAM to do what I wanted (or maybe I’m remembering it all wrong and I did something else by accident to make it work).
I can’t set a fair machining region if MeshCAM won’t let me zoom out a little. FWIW I’m using the Mac version on a Macbook Pro. When I got it to work properly I was using my desktop Mac Pro with an external mouse (as opposed to the built-in trackpad). Maybe that made the difference, but the commands should seriously be the same regardless of input device.
Also, I still can’t figure out how to really define supports. I feel like this is directly correlated to my question above. I’ll define a support (even when my machining region is set…albeit not the way I want but still outside the dimensions of the drawing) it doesn’t show up anywhere. If I exit out and then try to add another support it asks me if I want to clear existing supports…so I feel like they got added somewhere but they don’t show up anywhere on-screen.
I realize that MeshCAM is low-budget, but I would like to see a better user-guide, more how-to videos, etc. Maybe it’s out there, but I’ve been unable to find it.
Any help is greatly appreciated. I’m mostly looking for how to zoom out when setting the machinable region (and how the supports are added exactly…there must be a minimum spacing between the boundaries before they’ll show up?).
