The openvoronoi library is optional - you can ignore this. I will reduce the verbal severity of this message. Did the process succeed?

You can choose the strategy "engrave" and pick a "pocketing" mode. Probably you will need to apply the "revise polygon directions" action onto the model first, since pycam uses the direction (clockwise, counterclockwise) for determining "inside" and "outside".

Hi Lars, I got these high processing times while using an extruded model (see other post). If I find a way to fill in parts, I won't have to do the extrusion part again, which will benefit processing times. Regarding the version: I used the one on Sourceforge that was downloaded most. I only found 0.6.1 that was higher as a version. Where is 0.6.3 ? cheers, BC

Lars — Fri, 17 May 2019 21:47:32 -0000

Extrusion is the conversion of 2D model into a 3D model. I am not sure, that this is helpful for you with your mdel. Since pycam does not support specific operations for parts of a model, I would suggest, that you split your model into parts that you want to engrave along the outlines and the parts that should be filled. This should allow you to select the proper engrave operation to each polcgon.

Lars posted a comment on discussion Help

Lars — Fri, 17 May 2019 20:49:45 -0000

Indeed pycam's perfomance is not great. Calculation speed mainly depends on the following factors: available processing power modelling density Maybe you can reduce the precision of the model within the range of your target application. Another thing: maybe you want to upgrade to v0.6.3? It does not really change the performance, but it may be helpful for other details. Your version of pycam is more than 8 years old :)

And that the magic is to cd to the enum32 dir, then to do 'python ./setup.py install' .

Ah - sorry for spontaneously jumping into scripting territory :) "sed" is a commandline tool for text manipulation. The above expression would prefix every line that starts with "x", "y" or "z" with "G01 " in a given file. This kind of tools is available in every unix-like environment. In your case something like "cygwin" (for Windows) would provide such a functionality. But I guess, this is not the best approach for you, if you are currently not used to this kind of tools.

Ah - I completely misunderstood your question (based on my overly quick reading attempt) :( No: such a GCode dialect is currently not supported by pycam. In case that it is tolerable for you to post-process the GCode on your own, then something like "sed -i s/^([XYZ])/G01 \1/i' FILENAME" could fix your issue.

Has anything happened with this yet? I have been using the 0.5.1 standalone on Windows. The parts I have made turned out nice, but I kept running into issues with the plunge rate. My solution was to change the GRBL settings for Z on the machine to the plunge rate I needed. Unfortunatly that limits all Z movements, not just plunges. I set up a Linux machine specifically to take advantage of the new plunge rate settings. I have installed .0.6.3 and have been getting a feel for the differences in the...

But this could conflict with a local usage of these positional registers (e.g. for a tool changer). Additionally I am not sure, if other GCode interpreters offer these commands, as well. Can you share a GCode file that exposes the behaviour that you desire? 2) I am used to position the tool at the surface of the stock...

I installed exactly the version of pycam you used, Used exactly the settings you used on exactly the same file. I end up with different paths and a hollow box. The Paths indicated are black lines not orange as yours (just as a side note, and the top curved surface is ignored as the box is sseen as a hollow container not a solid. It then machines the sides and the bottom flat part of the object completely ignoring the curved surface. Now I am stumped. The only difference between what I did and you...

I did not notice the little small font 0.6.3 at the top. I guess no-one will find that easily, but it is probably still an unstable version. The font fo 0.6.3 is about 20x smaller than the 0.6.2 and other versions so I never took notice of it till you pointed it out. Thanks P.S. Please consider updating the tar.gz file INSTALL.TXT to contain the instructions what command to run for installation e.g. $] python setup.py install as non-python programmers or general users wont know how to install pycam...

Your example About page mentions Pycam 0.6.3 . There is nowhere I can find that version. Where is the download page for 0.6.3 ?

That is what has been driving me nuts for more than 6 months! Wish I knew about the bug. This is really helpful thank you very much. I will post back once the newest pycam runs.

I am glad, that it is helpful. Indeed I am quite confident, that you can achieve the same (with the same settings) with v0.5.1. But an upgrade should not hurt. Regarding #136: you see the effect of this issue in the video: the surface moves on top of the model are stright instead of being bent down. The issue is not fixed, yet. Thus you should just pick the other grid direction ("y" instead of "x") in order to work around this effect for now.

That really looks great ! Wish I could get to that stage, been trying for months. I will go over your video carefully. Was it issue#136 that caused it to create only a single cut along the surface ? I will install same version pycam as you used to repeat your steps. Thank you very much Lars!

Here is a good example I am trying to CNC a missing piano edge. There is just no way I can get pycam to generate gcode that makes sense. Either it just creates a surfacing routine or it just plunges and cnc's a single line where it has to do the entire surface. I attach my STL model and a config. I tried about every possible config and nothing works. The one added is jut my latest attempt. As you can se this is 2.5D and way inside the capabilities of Pycam according to the manual. To get G-code though...

For other interested readers: the referenced model is attached in another thread: https://sourceforge.net/p/pycam/discussion/860183/thread/6980228f/ I tried to create a toolpath for your model. I think, I created a usable toolpath. Please take a look at the attached video, that I recorded. Please note, that the resulting toolpath exposed issue #136. You will need to change the grid direction of the surface process in order to work around this at the moment.

No problem, I since movedon to dxf2gcode which worked great so I did not have to deal with pycam config problems. So the above issue was resolved using dxf2gcode. I have STL files I need to CNC and that I need pycam for, so I will post it in another topic.

That figures, maybe they should call it something different rather than just adding ++. No way for a user to know. Thanks that solves it.

Sorry for forgetting your question! 1) the bounding box is used for specifying the depth of the gravure (see http://pycam.sourceforge.net/faq/). This is a bit counter-intuitive, sorry. 2) No, the 2D toolpaths do not try to guess the physical properties of your setup. But it should not add moves within circles that are smaller than the tool radius, if you enabled tool compensation. Regarding gravures for 3D objects: this is an interesting feature, but it is not here, at the moment.

pycam++ is something different. You should refer to "pycam" (without "++") instead. You can also find a bit newer things here: https://github.com/SebKuzminsky/pycam/releases (documentation lacks a bit in this regard)

Sorry for forgetting your question! Where exactly did you experience an issue? With a 2D model? Maybe you can share a screenshot?
