I Really Like MakerCam for A Lot of Things. . .

But sometimes you just have to wonder what the #@!! it is thinking sometimes. I just want to engrave this bible verse for a customer.

For those who don't know, the green lines are rapid movements from one place to another between cutting.

Yeah, I find it simple and straight-forward to use as well. One way to avoid this is to select each pocket’s path(s) in turn and assign CAM settings individually.

There is a utility: https://github.com/alsliahona/gcode-optimizer (listed at http://www.shapeoko.com/wiki/index.php/G-Code_Utilities ) which will optimize such a G-code file though.

Yeah, I was hoping I wouldn't have to resort to that. Sometimes it will play nice, sometimes it won't.

I guess time to repeat the commands for each line.

Have you tried the gcode optimizer I posted?

Actually, I just did. It took a lot longer than it should have because of an unexpected error between the keyboard and chair.

Quite the improvement. Thanks for the recommendation.

EDIT: It cut the time from 23:34 to 11:39 according to ChiliPeppr.com

in some cases yes. But that is just ridiculous.

The other day i milled out 2 small pockets about 12inches apart. It actually chose to go depth pass per depth pass (switching pockets all the time) instead of doing one pocket full depth and then the next.

result, it took more time travelling than actually cutting.

i know professional tools allow you to choose how it generates toolpaths, but afaik makercam is just a take-it-or-leave-it kind of tool.

Yeah, I learned that the hard way. I set up to cut 25 holes and it started doing the same thing. I stopped it, redid the code to do each hole instead of the group. Just another one of those "quirks" of MakerCam, but I'll live with those quirks until I get to the point where I am ready to drop the $$$ for some professional software.

MakerCAM is opensource, d/l the code and fix it?

Has anyone run the optimizer app in Win 10? I tried but it just opens and closes in the blink of an eye.

Let me know if there is a workaround

Thanks
