Re: Helix Contouring

Thank you Julian for your comments. I have written this code and I am sure this is the longest documentation anyone has ever written about it, including myself. This was written originally for my own need of generating the ramp entries for cutting with tools which are not able to plunge straight dow...

Re: Creating CNC roughing and finishing passes

I was just wondering if roivai's optimization has made it to the official code base yet. I downloaded the latest 0.18 release and redid the post-processing of a project I was using some time ago and... as far as I can tell there is no difference in the generated gcode file. https://github.com/FreeC...

So if I want the original too, i need to add it when I generate the G-Code?
Yes, just keep both the original and the array operation enabled and when you generate the G-Code with post processor, both the original and the copies will be generated.

Re: Array - Bug

Hi I'm just using the Array- Feature of Path. If I'm right the offset should be the distance to the next item. But the first item is shifted by this offset too. Is it a bug? packmers! :roll: Not 100% sure if I understood what you mean because just now I cannot start FreeCAD and check.. But if my me...

Re: Ramp entry (helix) too steep

Hi roivai, yes it's the helix ramp, - and file is attached. Thanks for the file. The bug was even more obvious than I originally expected. When the dressup was searching for minimum Z on the path, it included the first edge from (0,0,0) to actual starting position. So it always found 0 as the minim...

Re: Ramp entry (helix) too steep

there is a new problem if using the ramp entry dressup: it only removes the ramp, not the whole material. rampentry.jpg Th screenshot is taken at a Millface OP, but the behavior is the same at Pocket OP and Pocket 3D. I suppose you are using helix method? I think I have seen that at some point, the...

Re: Creating CNC roughing and finishing passes

1) The SampleInterval and Stepover properties really should be exposed in the task panel. They're already available in the property pane but both are likely to be tweaked by even casual users. Here's how it looks now: 2018-09-25-205829_3840x1200_scrot.png I did not work on adding support for rounde...

Re: Creating CNC roughing and finishing passes

I can think of one use-case but I'm not sure it's worth considering: If you're familiar with gcoderipper , it can adjust gcode to correspond to a probed surface (like engraving on the mouse). It does this by doing a bilinear interpolation of the gcode points based on the probe data. I've built some...

Re: Creating CNC roughing and finishing passes

I changed the optimization a bit - now it is based on general "is point on a line" check. I think it is ready for pull request. Only question for @mlampert or @sliptonic or others: Should I add a parameter to enable/disable the optimization? Is there a case where user would prefer a fixed pattern of...

Re: Creating CNC roughing and finishing passes

Hmm, said I'd work on the optimization some weeks ago, but finding spare time turned out to be harder than expected, once again. But I finally managed to make a trial on optimization of the OCL DropCutter output in 3D Surface OP. Still some polishing to do but I'm well past my bed time, so thought I...
