- In this video we will explore a Christmas gift idea made with the CNC router. We will use the path workbench to do some engraving of a sketch and machining some wooden coasters.

I LOVE your yellow pointer with the reddish hue around it.
This is great
Thank You
You are welcome 😉
Really enjoying the Path workbench videos!
Glad to hear it
Great video with proper sound and proper instructions. Thanks for sharing. I am busy getting the hang of FreeCad and again thanks to you.
You're very welcome!
15:49
8 (mm/s) x 60 (s/min) = (480 mm/min)
7 " 420 "
450 " 27000 "
3 " 180 "
If you want 450 mm/min, you would enter 450/60 = 7.5 (mm/s)
Thank you Cathy, that makes a lot of sense. - I am not sure why we have to rapid in seconds and feed in minutes. I will bear that it mine for the future.
Excellent video mate, well done. Very well explained in a clear voice (without annoying background music) that even an old geezer like me can follow because you don't talk like 60 words a second like some others. Liked and subscribed. Thank you
Thanks mate. I appreciate the feedback. I have been back and forth with back ground music 🎶 and it seems it doesn't add very much to the user experience. I am thinking about doing a video on boolean operations next. Hopefully you'll enjoy that one.
@@Adventuresincreation Although I have no clue what "boolean operations" are, I will watch your video and hopefully will underdstand and use them. I am very new to FreeCad and you'll be my teacher LOL
I will explain it but essentially it is an operation between two bodies that is either additive, subtractive or multiplying (common). So you can create a model that is a combo of more than one body. It is great way to create more complex shapes.
@@Adventuresincreation Looking forward to it.
Have you thought about making a video on how to work with Texts/Shapestrings within FreeCAD? I am greatly enjoying your tutorials and have gotten somewhat used to FreeCAD. It's a bit quirky at times but once you get used to it, it's not so bad. I am assuming that other CAD software is equally unintuitive when it comes to being "art-sy". Embossing or engraving text has been a bit of a learning curve for me. Thanks for all the videos!
Thanks, I will create something engraving text with shapestring
Brilliant! I am enjoying your videos very much. your narration has the right amount of detail, not off in the weeds but very informative about possible tricky spots. Question if you don't mind. I've got an SKR pro board on my Lowrider CNC and had the impression that Freecad Path workbench couldn't put out gcode that's compatible with Marlin. Are you finding that the gcode is ok, or do you need to do further post processing of it? Many thanks!
I created a variation of the GRBL post processor for my mpcnc that seems to work well. There is a Marlin post processor but my set up does not like comments in () they have to be preceded with ; and tool changes require an M0 so that's basically what my version does. I haven't had any problems with it.
@@Adventuresincreation Great to hear. I'm going to have a look at that. I'm new to this and like the path workbench. I wanted to jump in with a cut in foam so I bought Estlcam but really like using FOSS whenever I can.
Really enjoyed all your videos on freecad. Am thinking of getting a cnc router, what brand would you recommend? I see the sainsmart has a fairly cheap one but don't know if it works with freecad tool paths. Any thoughts?
Thanks for the feedback. I personally have an MPCNC I think which one you go for is dependent on what you want to do with it. If you are looking at cutting metal then rigidity will be key. It's hard for me to recommend without knowing more about the use cases.
Could you please do a video on creating coasters with an SVG image engraved on it? That would be so helpful 🙏
Sure, how do you want to do the engraving, with a laser or a cnc?
@@Adventuresincreation With a CNC. For me it isn't clear where to use which bits. For outlines I can use a V-bit, that's simple. But what if the image contains filled parts. Do I have to switch to an end mill and make a separate path for it? Also the placing of the SVG onto a model (coaster) isn't clear for me. To see the whole process would be very helpful
Great video! I look forward to seeing more in the future. Is Freecad able to replace F-carve completely?
Unfortunately freecad can't do the f-engrave stuff yet. It can't do the edges that have variable heights. (vironi maps)
@@Adventuresincreation I'm new to CNC...so what other things Freecad can't do when it comes to CNC woodworking?And what software can do everything and do it either free or the cheapest possible?
@@encapsulatio Brother I think this question needs time for you to slowly put your self into Freecad and find out if you love working with it and learning it, for If you really do and know a little bet of programming you could always contribute to it, and I think that is what I love about freecad
Very important step at 6:10 to pick 2D geometry for a new job in path workbench.
Thanks for the feedback
The feeds are in mm/sec which then mulitiplied by 60 to give mm/min
That is correct, get it wrong at your peril
What is your technique for doing tool changes on the mpcnc? I noticed you created a post processor that deals with tool changes. Would you pause the cut, move to a clear area, change the hit, do the z touch probe and continue the cut?
Yeah, what I do is pause. I then move up in the z axis, change the tool, move over from the cut area to the stock and set up on the touch plate. It works great if you use octoprint. I have been doing a lot of it lately.
One question please :
Adaptive clearing, start depth 16mm, step down 5mm. How can I prohibit the endmill to lift up, when it changes the steps?
You can change the safe height to limit the amount of lift
Спасибо. На моем родном языке очень мало видео уроков по freecad❤
Мне жаль это слышать. Я надеюсь, что вы сможете следить за этим на английском языке. Если бы я знал русский язык, я бы, конечно, снял несколько видео на этом языке.
I have followed you and everything went as plan. I just loved it, sometime later I came back to this lesson because I had forgotten some things to refresh. But now no matter if I start the project in the latest or the older version I have as soon as I come to the ( Path and then job) the shape is gone and it is worse in the latest version. Do you know what I am doing wrong. I just dont get it!!!?
I think you just need to go to the model tree and click on the part then hit the spacebar.
@@Adventuresincreation Thank you very much for taking time to answer me. Yep it was ME AGAIN :) what you wrote offcurse is the way, but there are slightly different between the new and the older I was using and I think it confused me. Anyways thank you again. Love your lessons and I follow everyone of them.....
THX for the Video, the speeds are set in the settings somehow, mm ---- inch ....
You are welcome. Yes, in the general setting you can choose mm or inch.
Ok you didn't show the actual engraving and cutting with the tool changes. Does freecad automatically stop the machine and hold thee steppers on the tool change or do you have to do something else ?
Yes, you can cause the cnc to pause for the tool change.
@@Adventuresincreation ok do I do that in freecad or universal gcode sender?
@@scotthow2933 in freecad
Ok thanks for the quick responses! I'll have to learn how to do that in freecad but you and your videos have helped a lot ! Thanks !
@@scotthow2933 no worries, you'll see it when you set up multiple tools
Why some operation don't have step down.
it just depends on what has been programmed
Super vidéo mais avec FREECAD 20.1 si je respecte à la lettre votre programme j'ai des erreurs.
Interesting, what errors do you get?
Can you share your mpcnc post processor for FreeCAD
Let me find a place to put it then I will let you know
Thanks. Really appreciated.@@Adventuresincreation
@@Rohit-oz1or You can find it here jobbos.com/wp/index.php/2023/12/05/mpcnc-post-processor/
i cant get path to do shit.
Are you using the latest version?
@@Adventuresincreation yes, its so confusing wont let you set depths or height wont cut a pocket unless its the zigzag. on and on complete pia. not new to cad cam. mc 9 and 10 surfcam, 5 solidworks, alibre, onecnc, f360.
@@toddsutton5672 you can set the depths in the operation. If they are greyed out just click on the symbol to the right and it will let you modify the depth.
