In this project, I have 6 tree decorations being 3d carved. The rough pass is fine.
During the fine pass, the top left decoration gets carved fine, the bit starts at the bottom and carves smoothly from bottom to top.
In the image, you can see in the second one, the top right, it starts in the middle. It cuts to the top, then moves to the bottom and cuts to the middle, leaving a line that is very difficult to sand off later. 4 of the 6 have this issue, but 2 of the 6 cut properly.
How can I prevent this? I just want it to carve from the bottom to the top, I don’t understand why it’s jumping around.
These photos are an example of the carve. It’s incredibly annoying to have the software not be able to properly address this. Now, I either have the last hour wasted, or I am able to fix it with wood filler and more time.
Hi Joel, I did try that. The results are similar, but not identical. I get a few finish paths that go from top to bottom, and a few that start in the middle. Thanks for the suggestions though!
I am trying out v8 now. It has the same issue, though not identical. I was able to trick it into a better carve by changing it to 45 degree cut. I have not been able to copy and paste it though.
and if you wish, then adjust either stepover, or add a successive 3D Finishing toolpath with the next size down tool until one arrives at the desired result.
In the end, I still would like to know how I can have the job start at the bottom, rather than in the middle. Any tips for making that happen? Or is it just a gamble each time, creating a toolpath and hoping for the best. Cheers!
I have a bit of a workaround. I imported my stl into Blender and multiplied the stl there, exporting all 6 ornaments as a single stl.
From there, I imported it in to CC Pro. I set all six up for a rough pass, and then used Joel suggestion to make a fine pass for each ornament separately. This would not work before, but with this workflow, once I was able to trick cc pro into a fine pass I like (well, close enough…lines within more easily sandable places), by changing the angle a few times until it would not start/stop in the middle of the piece, I could select the next outline vector of the next ornament, duplicate and “use selected vector” to repeat the exact same response from the fine pass…tricking the algorithm, I guess.
Something about the stl being one file seems to have helped a lot, rather than an stl multiplied within CC Pro.
