FreeCAD- The Powerful Path Workbench for CNC Maching and Gcode|JOKO ENGINEERING|

[@Dragonborn__]

Been using Freecad for a little over a year now to design parts that I 3D print or send off to be machined. Getting a CNC router now and this was a great introduction! Thank you

[@mahatmamv]

I learned a new function of amazing Free Cad! I'm a 54 years old beginner for CNC. I tried to generate gcode. It runs in simulator as camotics. When my CNC will be operating I'll try. Thank you! I'm from Italy too!

[@flypic1098]

Very good. Lots for me to learn I was a CNC Turner for 25 years but never used computers to write my programs. All done the old way ! Thanks. Jim

[@mortimersnead5821]

You mean you wrote gcode? 30 years ago, I had a job in a small pc board fab shop where my job was to look at blueprints and turn them into gcode for the cnc router, which cost the price of 2 Cadillacs.

[@power-max]

Seems like something changed in the 0.19 release, when I click add (5:30) I get a file window that opens with freecad files present in a freecad install directory. I select one and click edit on whichever tool and I'm presented with Tool Controller Editor which only has feeds/speeds options.

[@Nets-nutsBr]

Hi dear. I was getting crazy with that Path Workbench tool. You made my day. THANK U! Really appreciate it!

[@MarcusPocus]

very well explained and i have learned the details which do the difference!!!

[@esarworks4963]

Hi, Step Over is typically how much of the tool is engaged in a cut. So for a 12 mm end mill you would not want to take a 12 mm wide cut (unless you are slotting). I good number is about 60% of the tool diameter. Broken end mills flying around the shop are really scary ! Thanks for the tutorial, nice to see free software making an impact.

[@JokoEngineeringhelp]

Great Comment thanks

[@peterbelanger4094]

That also changes based on what material you are cutting and the quality of the tool. Harder metals you are going to want to take smaller bites out of. You also have to factor spindle r.p.m. into it.

[@evilinnovations]

When creating a milling operation, I hit Apply and it doesn't make the green path like in your video. I go to the CAM simulation and it just bumps down and then back up and says its done. No milling.

[@stevenfixo]

will try out, thank you for your detailed explanation.

[@edsonferraz1]

I using the release 1.0.0, but not include o Path Workbench. Do you can help me? How to include this workbench?

[@JokoEngineeringhelp]

In versions after this, it should be called 'CAM' and come with the base install of freecad.

[@Bobby-kv4gc]

Very useful video - thanks. I would like to suggest that you use default user interface colours on your videos. When you're a beginner, you want to recognise what you're looking at - I don't think the non-standard UI adds anything to the learning value. When I look at it, everything is a little unfamiliar.

[@ArchaeometallurgieDe]

another excellent video. thanks for making them for us! I surely learned a lot again.

[@thejackal5099]

does this work with cnc plasmacutters?

[@metaldetective6761]

Excellent. No time wasted

[@warrenking1815]

I have a question, I watched the video and again it clear and concise. The only part that I do not understand is how you set the cut depth for the pocket operation. I have a 3018 and need to constrain the amount of materal cut per pass due to the limited power. Is the number of passes to cut the pocket something that can be set?

[@JokoEngineeringhelp]

You should be able to edit your step down by gong to the tree on the left, Job>operations>Pocket_Shape>RMB>Edit>Depths>Step Down> Click on variable symbol and change to desired value

[@warrenking1815]

@@JokoEngineeringhelp thank you I appreciate the answer and your taking time to answer

[@carreteFILMSPro]

Can it handle 5 axis CNC's?...

[@rupskiralli]

I am exploring the path tool at the moment, and I have one issue: the starting position of the tool. I see that on your video, the starting position appears to be inside the object too. I can set the starting position in several options, but the simulator does start still from 0,0,0. Also the G code seems to have this initial position in 0. How to solve it?

[@csquaredvisionsfpv8964]

(Tool Call,g54 and things up here then you can insert something like this depending on your part or datum G00 Z5. (rapid 5 inches above Datum) X0. Y0. (rapid to xy 0. or wherever you need the cutter above the part) Z.1 (Rapid to .1" above part) G01 Z0. F10. (Feed at 10 ipm to Z0.) Then this would be your code for milling the part. This would put your cutter up and feed slowly down to where you tell it to with no surprises. if 10 ipm is too fast or the x and y are wrong they can be changed. I'm sure theres a setting in freecad that may be a little easier to apply that i cant find either.

[@ChainsawDNA]

Great tutorial!!

[@pmmc2023]

lol "make you dangerous" is probably the best line i've ever heard in a youtube tutorial

[@MrCoffeypaul]

Wireframe is an easier way to pick edges! Hopefully you might have a look at the engraving feature in Path? Also the tool page will allow you define a tool using Python and import it in but unfortunately am forgetting how to do it. This workbench is not without its flaws but definitely promising.

[@JokoEngineeringhelp]

THAT is a good suggestion. I'm gonna remember that for fillets. I need to learn python.

[@juperrr]

Hi there, thanks for the video. I have created a path profile operation and I have a problem. The profile is basicly a circle, but when I read the g-code there is this "K" coordinate, I think it is Z offset. The thing is LinuxCNC doesn't like that "K". It can't run the program with it. I removed it manually from the code and it works perfectly. The question is: Is there a setting in FreeCAD so that this "K" doesn't appear in the G-Code? Thanks a lot !

[@JokoEngineeringhelp]

That's a great question! I'm not sure; sliptonic channel might know and the freecadweb.org forum is usually helpful for things like that

[@brucewilliams6292]

You do a great job with all your videos and they are sincerely appreciated. Can Path handle 5 axis machining?

[@Vesalempinen]

[@sairfan06]

and then how do you get g code to cut?

[@werkzeugmann6224]

[@AsMazasDebeselis]

How about the bottom side?

[@JHV166]

The problem as I see it is that Freecad does not respond in the ways that many of the tutorials portray it.. In the Path workbench, my copy does not have the same menu structure/choices that are displayed in many of these tutorials. I haven't modified the program via preferences so I really cannot understand where the issue lies (Version 0.19.)

[@JokoEngineeringhelp]

The version in the video is older than 0.19. I would say a channel called sliptonic is the ultimate authority on path if you are interested.

[@ianboard3555]

Very interesting. I would like to see a little bit on the post operation.

hi mr:joko are u able to teach about free cad? online? i download it already but i need somebody to guide me how to do .

[@dineshr6713]

is Free cad do CAM from .dxf?

[@JokoEngineeringhelp]

If I had a DXF, I would probably use it to manually generate a 3d model and make the tool paths from that.

[@edwardspooner8488]

Great explanation. Is there a Path method of coping with bevels and fillets?

[@liamstone3437]

I have a fresh install of Linux Mint 20 with FreeCad 18.4 - I tried making a simple disk in Part, Moved to Part Design to create my body, Moved to Path and I got this error message: "libnglib.so: cannot open shared object file: No such file or directory" - I then looked that error up and found someone had installed libnglib with this: sudo apt install libnglib which did not work for me so I saw someone else did this: sudo apt-get install -y libnglib-dev which I tried and it seemed to install something. Still no joy even after restarting my computer. I get the same error when I start path. I do not get the dialog to select a body. Any ideas? Note I also do not see the Path tools in my pallet after I make the error dialog go away.

[@JokoEngineeringhelp]

I have never had any problems such as that honestly - I think this one would be for the freecadweb.org forums

[@dmsentra]

Does this send out gcode to the machines too?

[@JokoEngineeringhelp]

Yes it does! See the post process option wiki.freecadweb.org/Path_Workbench

[@SomeGuyInSandy]

[@JoyeMusiccom]

What version of FreeCAD are you using? I'm having trouble selecting the faces of my part for the operations -- It seems like it wants to select the tool path lines or maybe the expanded fictitious clear box for facing. I'm trying to make a path on an imported STL that I turned into a FreeCAD solid. I wondering if maybe your version fixed that issue. I'm running: OS: Ubuntu 18.04.4 LTS Word size of OS: 64-bit Word size of FreeCAD: 64-bit Version: 0.18.16146 (Git) AppImage Build type: Release Branch: (HEAD detached at 0.18.4) Hash: 980bf9060e28555fecd9e3462f68ca74007b70f8 Python version: 3.6.7 Qt version: 5.6.2 Coin version: 4.0.0a OCC version: 7.3.0 Locale: English/UnitedStates (en_US)

[@JokoEngineeringhelp]

It looks like your system checks out; I've never worked with an imported STL before. I'm using 0.18 and if you can, I would recommend a .STP file instead. Would that work?

[@JoyeMusiccom]

Thanks for the reply. I found out I can click the faces when I zoom in. It's like it wants to select the tool paths with priority over the faces. IF you use a small tool, there are toolpaths everywhere and you really have to zoom in. I wish there was an easy way to hide the toolpaths! I seem to be able to hide everything else. The other thing that got me was when you run simulation and hit "OK" it generates a CutMaterial item at the bottom of the tree and messes up the selection. Hiding that (or deleting it until I need the gcode) seemed like the trick. Also, doing through-slots only seemed to work with ProfileFaces when the sidewalls were selected. I like that Adaptive is using the trochoidal cuts. Also, I'll try STP next time.

[@TheScarvig]

@@JoyeMusiccom if you hide the whole job (select the job and then press space) you can then unhide/hide individual elements like the individual paths, the stock and the model the job uses (which can be different from the model you selected at the beginning because you changed the origin for the job -> i use a modified 3D printer so i have to stay in positive coords and thus place my origin in the bottom-front-left corner of the stock)
