17 out of 54 videos so far! I can't believe how much you have taught through the course. I don't skip a single video. You have done such a phenomenal job developing this curriculum and order of lectures and content to really reinforce this learning. Can't believe I'm only a quarter of the way through and already catching up to where my knowledge was in inventor. Thank you!
Oh wow! That's great to hear. I have no real gauge of how i'm doing with the videos and comments like yours really put what I am doing into context. Thank you for your kind words.
Hey there, I found your channel a little bit ago, I started 3d printing about a year ago, but so far I've only printed downloaded models and did some editing from the slicer itself, since I really had 0 knowledge on CAD or 3D design of any kind, I've learned SO much in the 17 videos so far. Thank you very much, it's a great effort on your part and it's greatly appreciated.
Purchasing and learning how to properly use a basic Ender 3 has been a game changing event in my life. Learning how to utilize FreeCAD so I can bring conccepts to life is going to infinitely expand my capabilities. Thank you for another greatly presented lesson!
Great to hear. I have the same printer and will be getting it up and running as I had a failed part damaged in transit. But the basic version is all I needed. Great to see your getting use of the videos.
Mate these are by a very long margin the best tutorials out there for FreeCAD. They must have given the auto constraints a big overhaul between 0.20 and 21.1 I barely get any redundancies unless I'm being stupid, the solver fixes most automatically, but I've seen on a few peoples videos now that it wasn't rare to have single geometries error just laying down the first shape.
Thanks for the detailed explanation. I was not aware of A2PlusWB, but can see how useful this can be. Nice that the export is direct to STL without having to use the Mesh WB.
Hi - it's your faithful viewer from Canada here 😉 I missed this video a few weeks back and just got to it now. I've been wanting to learn the A2+ workbench for some time and this was a good intro for me. Hope you're planning a more in-depth video on this as it looks like a straightforward approach for simple simulations and is close in style to the Fusion 360 one I used years ago. Thanks again for all your efforts - it's really appreciated.
Nice to see you back 😁 yes there are many planned, I am actually in the middle of planning one now, just took a break to catch up on some comments. It's a great little workbench and has so much to offer. Glad your finding the videos useful 👍👍 and thank you for the comments and support.
I have wanted to do a print in place design for quite a while so this wa a great start Also almost able to keep up without having to stop video and wind back! Thanks! 😀
Great to hear that your progressing. I was going to try to do one of those snakes that you see but I thought that might be a stretch to far for the video. Glad you enjoyed.
That was so good! I kept adding links and moving them to see what would happen. I think I need a faster computer though; there was some lag here and there. I've been watching one of your videos every day. I'm already able to do more on FreeCAD than I could do on DesignSparkMechanical. My current aim is to make a set of two spinning gears. ie. draw the gears on FreeCAD, animate them and, when i'm happy with the result, 3D print them. I can see that you have a video about gears, so i'll work my way up to that video. Thanks for the great tutorial.
Thank you for the feedback and sharing your learning journey it's great to hear how you have progressed. The video you are talking about (think it's the one with the green and red gear thumbnail in the learning freecad series) I think will help you do exactly that. Actually it's basically covers what you have described. Happy learning 😊
Great to hear, did you get that lovely satisfying snap when you loosened up the joints to break any loose filament, 3D printing AMSR 😂 Glad your enjoying the videos
@@MangoJellySolutions I wasn't paying attention, plus I added a few supports, so I had to remove them first. I'm not sure it would have printed with out any and I couldn't tell from your video
Thanks for the great videos, they have really helped me to learn Freecad, have you every tried to create a frame/chassis out of tube sections and assemble using a2plus? Then potentially using the assembly to create technical drawings of each tube with the appropriate cutting angles?
You make super tutorials with excellent choice of topics. Thank you very much for your good work! One thing however that could be improved is the quality of your audio. The high-frequencies in your audio are too loud and dominating with lots of loud "Sssssss" sounds.. it would be good (ie my ears would much appreciate it) if you could find a way to tone down those high-frequency sounds, to make the audio generally smoother and more mellow. Cheers.
Thanks for the comments I have been trying to improve the audio lately as I just use the internal microphone on the laptop but you are right I have listen back carefully and I can hear those high frequency on the S. I want to create a better experience so I am looking into a microphone to improve the experience after your comment. Thank you for the constructive criticism always welcome.
@MangoJellySolutions - Another great tutorial. I haven't checked yet, but was just wondering - could you do a tutorial on how to doing something like draw a zigzag around a cylinders edge, that can be used for boolean operations? I've never found one for any of the CAD packages I've used and have need for such a technique. Thank you
Hello, Thanks for excellent tutorial, May I ask you why my exported links are not preserving circular edge constraints when exported(they are not connected as they are in workbench)? Thanks for helping in advance
If I wanted to build a longer chain, do I need to add each link individually, or can I iteratively copy the existing chain to get a longer and longer one. Duplicating the three piece chain breaks all the links in the duplicates, so I'm back to moving individual links about.
So, what you can do is save off say three or four links as a sub assembly and then link those sub assemblies together. I do have a few videos about sub assemblies in my collection.
Im in FC 21.2, when I imported the group at the end the three links have a large amount of separation between them. They are in the same position as saved (stl file) but moved apart. I have not been able to find a setting for this (yet). ideas?
everything going fine until i export the files as STl then when import them back as one file STL.. nothing appear in the screen i did it multiple time then i found this hint in the comment section and i follow it and it did the trick load mesh workbench, convert shapes to meshes from the list mesh (covert from shape) and then export the converted meshes as STL
For some reason my links when I exported them are not constrained as we set them up to connect. All three of my links saved as an STL with each part separate but it oddly maintained the same positioning that I moved them in with the "Move selected part under constraints". It almost looks like they have an equal offset spacing.
Hello, Again. I have finally tried this. But It looks good on FreeCad but when I export it , all the link came out separately ( Bambu studio) Not sure why...
It's really down to personal preference but I find A2Plus is much more faster to get an assembly up and running along with the addition of simulations.
I can't get the offset for the circ edge constraint to be 0.5 it will not allow the input of 0.5 , only 1mm movements. :( I have tried re doing it but it won't allow. FC version 0.20.1 Edit: I centralised the 2 links by adjusting the z axis placement of link 2 to zero, this put it in the middle. I wonder where I strayed from the tutorial....
I'm not totally sure but I just had the same issue in 0.21.2.I used your workaround. But then went back to the original sketch to modify the "pill" shape. When I "updated imported parts". the links were at crazy angles.I deleted them all and re imported each link. But this time I used Add shapes not add parts. Im pretty sure I used add parts first time around. Anyway this time around It would accept .5mm no problems...weird.
HI, I followed this lecture step by step but at the end i am facing a problem that when i create stl file then the position of the parts changes and not at the same place where they should be. How i can resolve this issue??
Yes I didn't use supports as it was the test print. I used the defaults from the machine just to get the proof of concept. But the next one I do I think I make a proper project of it.
Thank you for the tutorials - I'm using FC V0.20.1 and installed A2Plus V0.4.60n to follow along the video. Some of the dialogs in A2plus are now a bit different to what's shown on the video, and the connection/assembly behaviour seems to depend on whether you do it with the drop down menu or the tool bar button. Also I was not able to offset the circle link by -0.5mm for some reason at the dialog did not allow me to type in -0.5. using transform to shift the part by 0.5 mm broke the connection somehow and I was not able to add and connect the third link. I fiddled with the units and set the decimal places to 3, and then tried again and it all seemed to work fine after that. Maybe just a glitch in my PC or something. I don't think that its worth remaking the whole video, but new users of the Tutorials should bear in mind. FreeCAD is up to V0.21 now. I will not be installing that until after I've gone through the Tutorials.
Hi Jorge, long time since you post that, so I hoppe you've already found a solution. One that comes to mind is to add a planeCoincident constraint between each top or botom of the parts. It's even a more robust solution, I think, because if you change the part dimensions, so that, for example, there is only 0,4 mm of play instead of 1 mm, the plane Coincident solution still aligns the parts, but manualy specifyng a 0.5 offset won't.
I have a question. When you 3D print that part, how does the printer go about not fusing the joints together? If the joints are all within each other, wouldn't the hot plastic fuse itself to each piece?
The gapping is enough to make a extremely weak bond so when you finished printing you hear this very pleasing 'pop' when you first wiggle the joints and everything then moves freely.
@@MangoJellySolutions How solid is that material you were using? The reason I ask is that I have a disability and can see this design as being beneficial as a key turner.
@@smiskowiak oh wow, that's a great application. If it was made using a stronger filament then it would be very solid. You can increase the radius of the hole and pin for even more strength. Here is a nice article regarding materials for 3d print all3dp.com/2/strongest-3d-printer-filament/
Hi - I'm newbee in freecad, and i love your tutorials, and I have followed this one, but when it comes to move the inserted link parts, I run in to a problem where in could only move them in 1mm increments, and i cant find where to adjust theese. Could anyone help with that?
I had the same problem. I solved it by just creating the constraint with a 0mm offset, and then adding a offset in the data panel on the left afterwards
Update, found the solution in one of the remarks below. Load mesh workbench, convert the shapes into meshes and then export converted meshes to .STL. The- generated STL file is smaller and the links are now connected.
I get the same behaviour - the links are correctly angled but far apart from each other... Maybe it's due to some change in a2plus? Actually... I tried linking the links in new file, using assemby4 and then exporting the file - the links are disjoined too! Now i'm starting to think it's something with freecad or stl export! Edit3: I found a workaround if you're looking for it: load mesh workbench, conver shapes to meshes and then export converted meshes - generated STL file is smaller and the links are connected. Works with a2plus and assembly4. You don't even have to use mesh wb export, just normal export of generated meshes does the trick.

There are simulation workbenches but I don't believe any of them have a level of collision detection.
Pinted OK!
Fillets cause often problems.I used a rotation from a half slot and so on.
