@@ericlotze7724 We can only hope. I have used Fusion360 way more than FreeCAD and immediately thought the user interface and and intuitive aspect was considerably better in Fusion360. FreeCAD was down right clunky but I'm still glad it exists since with AutoDesk and their normal mode of operation they could pull the rug out from everyone in an instant. Cloud-based software sucks.

Some of the problems that are attributed to FreeCAD should really be thought of as Open CASCADE concerns. (OC make the CAD kernel). When I started using FC earlier in the year there were points when I became very frustrated. (I have been using AutoCAD and MicroStation for decades). Eventually I turned to some KZread tutorials. Have a look at these fellows in particular, Joko, sliptonic and Ha Gei. There are many other FC videos, some perhaps more pertinent to whatever you're trying to do.

Nice to see the FreeCAD movement develop, i would be interested to know about your experience with FreeCAD.

This guy has so much energy! It's contagious! Your vids get me in the prototyping mind set. Keep up the energy!

You are definitely getting better in editing your videos! Keep it up :D

You've come so far and made some much progress. Congratulations. Thanks for sharing this journey with us all.

Loved the freecam montage, and the tensioning mechanism is brilliant!!

Would be cool if the Index design standards had conventions for stamping 3D models with their version numbers in discrete places for traceability!

This channel is SERIOUSLY underrated! Love the videos! Hope ya make some more videos on other projects as well...

With the bullshit fusion pulled I hope everyone starts moving to freecad so it get more support and gets better and better

Nice work! I was just taking a look at your Index repo and wondering when the branches were going to be merged. The over-constrained thing was something that had been concerning me (not just your design, so many others!), so glad to see you've fixed it!

Your energy is contagious, and you're doing some really solid engineering! Keep up the good work! I really like your rubber band shock absorbers on the vacuum, that's an ingenious low-cost solution. Rubber bands do break down and get brittle over time though, so you might want to check out buna-N O-rings if that becomes an issue.

Regular office rubber bands have a very short life span, they dry out and crack after a few months.

Agreed, I have had the same problem with rubber bands I tried using on my 3D printer to lightly constrain some parts; they work for a while, but the problem is that standard rubber bands have no stabilizers so UV and ozone break them down quite quickly and they go brittle and fall apart. Proper O-rings or silicone bands/elastics will be much better and will last.

Fantastic job ! You could use few strands of filament ziptied together inside the umbilical to stop it from sagging.

Or "music wire" is good for this too.

I'm not sure of the mechanical design issue it addresses, but on most triathlon aero bikes, track, and old vintage bikes, they have a similar rear hub tension adjustment as your 3 wheel gantry setup. They always have a small spring over/around the tension bolt threads. I think it is there to prevent vibration from working the bolt out over time. It's fairly universal on bikes with slotted dropouts and this kind of tension arrangement. Thanks for the upload, and for tackling freecad. Be sure to make notes on how you do stuff in freecad. Don't be like me and have to relearn the same thing a few times over. -Jake

The realthunder stage3 branch is quite good - the official version moves quite slowly. But it gets better

4:15 adding a light spring might reduce the need to manually tension, and will be more reliable in terms of any nuts getting a little loose, or plastic stretching.

Awesome build! Now I am hooked to build one myself :D I also wondered why so many 3D printers use these 4-wheel gantrys. It was problematic on mine. Basic engineering principle - do not over-constrain! A slot hole and reliable tightening hardware could solve so many problems in hobbyist hardware. Kudos to you for doing it right!

How ironic, I just started learning FreeCAD in earnest last week!

Think I have watched 5 Hours of your Build. All I can say is amazing work !!!!!!! Dunno if I have the energy lol But would love to give it a bash to build. Thanks for all your commitment & enthusiasm.

Welcome to the dark... ehem, I mean the light side of libre / open source CAD.

I love FreeCAD. I can design anything 3D with it.

Thanks, for making my day Stephen

Maybe I was using it wrong, but I found it really frustrating to make any later adjustments in FreeCAD, several times the whole design just collapsed and needed re-doing like half of constraints after some minor adjustments of base shape or something. Now I'm using mostly OpenSCAD for technical stuff, maybe first initial design would be harder to do switching from visual CAD, but result is rock solid, maintenance of evolving project would be much easier, scad files are source code, so version control, pull-requests and applying patches would actually work.

The double-umbilical look is fire

If the rubber bands get all crunchy, you can use o-rings too for that kind of mounting.

Why haven't I seen this project before!? (Just got recommended one of your videos today) The world needs a RepRap equivalent for circuit board assembly, and the migration to FreeCAD is really refreshing! (I'm always sad when a promising project is tied up in closed design software formats.) Thank you for this, I've subscribed and I'll be watching development excitedly in the future.

Simply great!!!

I love the enthusiasm you show, and I really love your approach to fix challenges. I'm really looking forward to the next project. Would it be possible to make the 3d-print for the syringe part available, together with the part list you use for the machine?

Dude this thing is going to be so cool when its done! Oh, thought, do you know if your frame is going to flip forward with the weight of multiple reel feeders? Thanks for bring us along!

I've just come across your work and am delighted to see how well you've put FreeCAD to good use. (If anyone is struggling to learn FC then the videos from Joko, sliptonic and Ha Gei might prevent further hair loss). Will you end up making further changes to the PnP machine after this iteration? I'd not heard of OpenPnP before. I'll investigate more now. Thanks

Love that Evan Kale shot :P

Very cool project. What is the knob arrangement we see in the video at @1:59? It looks a bit like a Space Navigator knob with some additional 3D printed housing.

Your workshop looks like my place... boxes, boxes, boxes. Happy moving! Yet more great progress in the evolution of the index... chalk me up for initial delivery of index controller PCB's. Not sure how you want to fund this, so kickstarting or secondary pledging I'd be up for.

I could be wrong but someone stated PETG has the lowest creep (the deformation thing), so I guess you should make your rail mounts from that as the carriage tension screws will eventually pull through the plastic if it's PLA. Oh I'm going to try steal the mounts for my printer :).

You could use "Fan Mounting Pin Rivets" on the pump. Rubber bands will get messy with moister.

how many parts per minute do you see the index capable of when ready? just a rough estimate if you don't mind.

Excellent 👍

I didn't follow the design that much, so simple question is there a valve to open to let air in or are u just waiting for the part to lose the vacuum, that could be the reason for parts that bounce cause the vacuum is half there while releasing the part.

8:45 shock mounts can be salvaged from old dvd/cd drives there are at least 4 (Maybe 8 I can't remember), in each drive.

Skip the wheels and use quality linear rails.

Is a pnp machine like this able to pick up big parts like an esp12F or esp32 module?

Just heat sinks for the stepper drivers? My drivers for my 3d printer always get hot if theres no fan directly pointing at them

Think I might jump in and build one of these.

thank you

Just awesome :-)

Got to ask, What plastic are you printing in? It looks like PLA, but i wouldnt trust PLA for a mechanical project. As while its stiff... it more prone to cracking under tension. But also (in my case with a enclosed printer build i did) PLA starts to warp and soften at around 40c. Or are you using PETG or ABS? In any case. its an amazing build.... I could really do with a PnP machine and this is giving me bad ideas to make one :D

Any chance you can share the STLs for the SpaceMouse wrist wrest?

Probably replace rubber bands with some O rings. Last longer and bit more rigid while still absorbing vibrations.

Can you do a FreeCad gotchas video? What did you learn by 'fighting your way though'?

Your desire to use GIT to track it makes me wonder if OpenSCAD would've been a better choice, but I understand the design pipeline is very, very different

Have you used SolidWorks? How does it compare to FreeCad?

I made a freeCAD video for remembering how to create an object with holes (think building "bricks"), then being able to modify ONLY one hole's diameter, and have ALL the holes get updated, AND the gcode automatically updated (ie no need to click on all the pocket operations again).

Is the freecad design on github yet the latest version appears to be 3 months old and still fusion 360

Why not use the ends with m5 thread in so you do not have to use all the t-nuts?

Sooo guuuuuud

I would like to see some precision tests with this machine, like how does it handle tiny little smd resistors for example, since even professional pnp machines for like $15k struggle with achieving 100% clean runs on boards with lots of small smds.

Morning awesomed sucsefully!

I would have thought you would have used the method that OpenBuilds uses where it has an eccentric washer that you can rotate to tension the rollers on the extrusion. It seems like you did something similar but with 4 rollers instead of the three that you just implemented.

Could this be made wireless?
