Thanks for the intro to FreeCAD! FYI as for the Z offset issue. Most machining controllers have a touch-off feature in the GUI. Enter the 2.2 offset there, which tells the CAM software the tool is at 2.2 instead of 0. Alternately, I sometimes just set the origin in the CAD to the top surface instead of bottom surface, just like you moved the origin XY you can move the Z.
Brother I have been scanning the internet for over 2 mounth now, and your video was the one which did it for me. You describe everything Perfectly. I really am Grateful and thank you and keep up the GOOD WORK. I do hope that you get lots and lots of subs :) thank's again :)
Thank you for that great tutorial. It’s much more straightforward than I expected, or you explain really well. It’s just what I needed to get me going, that and I also use UCCNC!
Thank you so much for your videos, after spending hours watching other videos making things much more complicated. Your videos are very understandable and easy to comprehend.
Yea the origin in FreeCad needs to be set to the top of the object and then you can avoid having to do that "negative number" trick that you're using. The toolpath you created thinks that your cutting tool is starting at the bed of the CNC, but you zeroed your CNC tool at the top of the stock. It's a little confusing at first but when you go to cut something everything becomes more clear. Good video though, and super helpful!
I'm new to CNC and FreeCAD, I think theres something you didnt do that made this video (and you) confused. Heres what I think... 1.You skip stock creation - basically you start from arbitrary coordinate ? 2.Since you do No 1, you didnt have a correct origin, you then need to move the origin to the parts itself which skip the stock. heres a better method IMHO - create the stock and align the origin to the stock face. Less headache and start backlash removed when the spindle start.
Hal yang sama juga terjadi dengan saya, mencoba berbagai software, yang cocok sesuai kebutuham saya. Mesin saya diy CNC GRBL, 2040 vslot, with dc775 300watt. Setelah lancar dengan yang kecil, baru mai mengaplikasikan untuk OX CNC yang besar. Terimakasih telah berbagi pengalaman 🙏👍👍👍
Just found your channel and already appreciate it, i'm curios as to what the "easier to use" software is that you mentioned in the the first few minutes of the video is. Thank you!
@@MikeTech41 Okay cool, I'll have to check it out. I messed around with Freecam earlier today and I already like it a lot more than CREO. The tool paths are a little odd but I can't really complain about something this functional when it's free.
Glad I found your video. I was thinking of getting a cheap router (retired just home projects) but have not yet figured out all that is involved in generated G-Code. I am using Fusion for the models, STL files, etc. so I understand that part. (have 3D printer for file input on chip). Guess my question is will this CAM free software run on Apple's MacBook Pro? I keep finding information that shows using a COM Port for inputs but as far as I can figure there is NO COM Port on the Mac. I also subscribed to your channel - Agian thanks!
I think the most confusing part of your video is that you did not notice that for CAM FreeCAD creates a copy of your part. And by default this part is not visible. So what we see in your video is a part oriented as one part of a construction or assembly. In your object tree on the left side this is the last solid you created from your mesh. But when you want to mill a part this often has to be done from all sides. So for every CAM job (= collection of single CAM operations) there is a copy of the chosen part that has to be oriented to the coordinate system of your mill. In the object tree there is a branch "Job->Model" and there you find "Model-heta_skik3001". This model is grayed out as it is not visible. Click on it, press space bar to make it visible. While in CAM (activated Path toolbar) click on your main model, press space to make this one invisable. Now everything should be clear how the whole setup is oriented. Be not confused about the first rapid move in the simulation. It always starts from the origin. In reality the first move is where your spindle is. I prefer Z-zero on top of the stock and go down with negative steps. But FreeCAD can handle different preferences. Try to use FreeCAD 0.19 devel version as this has a much improved Path toolbar aka CAM system and be part of the community to improve this really good but nearly unknown CAD/CAM package. But I also only use it for CAM - so far. HTH
@@brycenorvell3428 , Hi, I would suggest to watch the videos of sliptonic. He shows how to setup Path workbench for creating toolpaths an howto generate g-code: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-jARnmuWm7n4.html Yes - this is not the latest hot stuff from freecad path in 0.19pre but it is a solid foundation for understanding the concepts. Please understand that FreeCAD is not a product but a project. So try to participate in the forums.
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 !
Lmao better then fusion cam you obviously havent used fusions cam it is also free and eons ahead of this. Really cool though hopefully one day they can catch up
