I keep getting a wire not closed error after trying to make the helix.

I would guess it would have been faster to repeat the square and do only two subtractive helix operations. Similar to programming in general, try to minimize the loop count for the most expensive operation.

You mention that the phone will be a little larger therefore we need to make the cavity a little bigger. But you made it smaller? The iphone dimensions were 138.3 and you made the phone 131.2 - subtracting 7.1mm. What am I missing? I'm trying to learn the program so I was curious why you said larger but made it smaller.

I'm a long time user of $olidworks (at work - but I'm moving on now). I like FreeCAD and 0.21 is quite reasonable. I think v1 and the TNP fix is going to be pretty good (seen a couple of 'preview' videos). You certainly can't beat the price (and that it works on Linux and Mac). There are still a couple of things that $olidworks makes a simple but are a harder in FreeCAD. I like the idea of modifying the colours to match what I am used to, and what would be even better is providing a customisation file as a link - save me having to go through and do it all myself! Cheers!

Like 911 🎉 good video, better than any of the other ones where I don’t got to build some crazy shi

Why not a polar pattern in the sketch itself?

Really hard to follow along

When attempting to do the helical cut, I continuously am getting a " wire not closed" error. I've went over all the constraints & it all looks good but still getting the same error. Any suggestions? Thanks in advance

Thanks. Short and effective.

I followed along, and I have a computer that is overkill for most operations. That said, this sucker still took about 2.5 to 3 minutes to calculate! Really nice trick though! :)

Very nice video👍🏻👍🏻👍🏻👍🏻👍🏻

Nice tutorial. I tried to follow it for another knob. But when i'm trying to make the second helix for the knurls, i get a error, face must be planar. Trying to learn how to use cad by mixing videos and testing for myself. You got any idea what could be my problem?

4 minute video filmed in 24 minutes...

Even If you messed around with some of the values, you are for sure my new reference for this topic. Overall, well done! 👍

How did you get to the 55 turns in the boolean pattern?

This is actually pretty good tutorial for many electronic enclosures that have common features such as ports, some mounting lugs, possibly snap-on edges. I covers almost everything except how to easily create sketch for all ports on one side that are subtracted from both base and a lid, which is not needed here. And maybe some info about mechanical tolerances, I've already seen parts that have like 1/8 on both sides and to my surprise it works on ~5x8cm raspberry pi box.

You could make a double hub gear without the need to use supports. Print the hub gear as you did, then print a washer or spacer the size that the hub would be. You can either glue the hub to the flat side or just place it on the shaft as a spacer.

I think it calculates slowly because of python?

Hey if anyone's software isn't allowing them to hit post-processing you may need to go to Edit (At the topmost left) -> Preferences (At the bottom of the pop up) -> Unit System -> Metric Small Parts and Cnc. If you had made a job before doing this I believe that you need to delete it and make a new one. I hope that this helps!

Thank you so much for the video; it was greatly informative and well explained.

How long did that take to print?

wow. I'm making a stevenson box for a esp32 temp/humidy station and this is not only exactly what I need, but I'm learning a lot of tricks in freecad I wasn't aware of watching you. Thanks.

It's slow and uses a ton of memory because Python sucks

Am new please inform me better, what is the difference between stl and gcode?

Threaded screws make huge files and take time to process as well. Lots of computation.

Could not get the subtractive helix to do what your video shows. I have watched this video several times and still cannot mimic your process I get "linked object is empty", also the helix parameters do not change when I select the z axis, height, turns,etc ANY tips?

One tip: you can calculate the number of polar revolutions in the expression editor by referencing the knob radius, pi and the knurl-thing size.

Just learning this WB. Thanks though. Please revisit, Version 21.2 no where's near this tutorial, Fanuc specifically and other post processors are broken. I have cam background, not impressed with surface machining versatility. Will stick with my 1996 package on old P2 and P3 towers with Win98 SE, I machine molds with it so, imagine a CNC router....

is someone playin honkey dong cuntry 2: tittys dong quest? the underwater levels? *GONK!*

Hello . How did you calculate the value of 0.633? It was a useful video

So good don't stop

What mode are you running on? I like the colors.

So now I see this after printing some dust caps for some solar filters. It would have been nice to have actual knurls. I used PrusaSlicer fuzzy skin to create a grip on the external surface.

Could it possibly be made MORE drawn out and long winded? I have a few years of life I need to waste.

Wow loved watching this

Great intro. Thanks for sharing this.

Nice

I really like your style and the practical models! I am learning a lot. Two things (and I get that this is a year late) that might make it a bit easier to follow - if you could refer to the planes by the name in FreeCad "XY, XZ, YZ" rather than 'top plane' that would help. Also - and you probably won't like this - when you switched the color scheme to match a different CAD program (SolidWorks?) that really threw me. If you are going to have a FreeCAD tutorial it might be best to stick with the FreeCAD defaults as much as possible. If find it harder to follow your sketching after you started using a different colour scheme. Not showstoppers - just minor suggestions.

one of those cases when after watching a tutorial one would have more questions then before. thank you, good stuff.

I have a similar problem as the number of faces increase. I made a plaque and it ended up around 1600 faces and everything I did after I padded the text just ran slower and slower, and I gotta say, from a design POV, knurling creates a multitude of faces.

I tried to accomplish this on my macbook and failed miserably. Any time he clicked and point to move it I was simply unable to do so. I just wasn't getting the same results whatsoever. Idk...

need to show how to convert to stl files, otherwise it was a good video

Maybe it's a good idea to point out that in Freecad, speeds are in mm/s and in general in CNC speeds are in mm/min. Probably that's why you went that fast on the bench. 30mm/s = 1800mm/min So probably your machine went it's maximum speed.

question; Is how to create gears in freecad Path Workbench for cnc, I can create and 3D print gears to make sure I have the have right gear reduction and torque. I want to then cnc cut the gears out of foam for casting into aluminum using lost foam casting technique. Problem is to create Gcode files in Path workbench. Any ideas would be appreciated.

I watched your video for 22 seconds! You must be smarter than ANY college professors I have ever learned under!!! NOT ONE of those professors played music in the background, WHY? Maybe they did not want any of us to get distracted!!!!!!!!!!!!!! Are you smarter than ANY college professors or do you just like to DISTRACT us?? If you take the music out of the background and re-post it I might watch.

The real bad ass thing about this tutorial is, that he is doing it without saving it! Thanks for the video ;)

thank you I subscribed

beautiful theme/colors there

How would you do this with RAISED text?
