The offset and overcut options may help with this.
Whoa! What a speedy reply! π
Well, offset is obvious, 0.5mm in my case with 1mm shaft, 45 degree blades. But what does overcut do? How does the amount influence the tip trace?
I had the impression that the commercial plotters are doing a kind of "in place turn" when changing directions, i.e., moving the head in a circle section around the blade tip until it is pointing opposite to the next cut direction. So a tiny hole is cut at best, while maintaining the given paths very well. Do you think this would be possible in GCodeplot as well?
It's been years since I've used this for cutting. I think overcut may be that kind of circle movement or some other solution to the same problem. I can't remember. I see that I used some code that I didn't write myself for the overcut, and it's pretty complicated code, so a quick glance at the code doesn't answer my question. I suggest the experimental method. You might set the output of gcodeplot.py to HPGL so you can visualize the output.
I am a C++ programmer and have never done anything in Python, unfortunately. Else I would try myself understanding and in case modifying the code. Thanks anyway for your support! Danke schΓΆn! π
Python is straightforward enough that one can do a lot of code modification without knowing python.
Uh, silly me! π
When trying to understand the ProcessPath
method I noticed that overcut actually is doing what I was suggesting! I was misled by the traces as can be seen in a GCode viewer, showing the strange loops at corners I thought were caused by the trailing blade.
But these traces in fact are drawn because overcut already does the corrections for the blade.
So excuse me for having raised a non-issue... π
Hi,
first let me thank you for this convenient way to use my 3D printer as a cutter as well! ππ»
I have a question on using it, though. Due to the nature of the blade's point running behind the turning axis, there are loops cut at sharp corners. Is there a way to avoid these? Something one could do in Inkscape to have the blade lifted, moved and lowered again at these corners?![grafik](https://user-images.githubusercontent.com/25884124/150568220-05d0e179-66cd-4fef-bace-b7ee3b81f542.png)
