Videos of LR3's?

four or five I believe. I’ve printed parts, but moved in the middle of the testing so I still haven’t built it yet.

My videos are not searchable yet, but are in my plog.

I like this one Dance, little CNC! - YouTube

I have recently begun printing parts and can’t wait to start assembly once my hardware kit arrives. I am seriously considering documenting the process with some YouTube videos since I also could find only two so far. This is my first CNC build apart from assembling my MK3 Prusa printer which I’m sure is a way different experience but the closest analogy. I’m sure I will face a steep learning curve and will likely encounter many headaches and hurdles on my journey. Perhaps documenting it would help others along theirs.

Please do! I love videos but really really have a hard time making them myself.

Really appreciate the extensive documentation. There’s a lot details to cover, can be hard to write content that’s accessible for everyone.

Personally got stuck and stumbled in a few places, appreciate this forum helping clarify details, and even let me contribute back some minor doc edits/clarifications.

Will share captured notes, clips and build montage that may help visual learners like my self. Maybe soon, I can smell the crown of victory, it’s close…

That reminds me, now that my LR3 moves about 10x faster, I need to re-do this video…

10x, that’s awesome. What enhancements did you make or try out? Which would you recommend?

For the most part, I just bumped up the max speeds for travel moves. It doesn’t cut faster, but it can really zip around.

The only real “enhancement” for speed is that it’s running 24V power.

EDIT: This post used to link to a DRAFT version of the Lowrider 3 video I was working on.

Read Videos of LR3's? - #26 by aaronse instead, have included link to final video there.

Hope that helps!

I let loose the max speeds +accelerations and zipped mine around the table too, it was super cool.

I think I’ll be tuning the cutting speeds a bit more when I get to cutting my thin polycarbonate sheets.

It seems like arcs and accelerations will be the thing holding it back, but there will be room for trial and error I guess!

What an amazing video! I haven’t seen the whole of it, but it’s very comfortable to listen to and the video itself seems well made. This is golden, I would recommend it for all who are considering both the LR3 or any other cnc.

That is really excellent. @vicious1

This is going in the docs for sure, just waiting on the final edit/s. It covers sooooo much, thank you.

Thanks for the kind “shout out” and for making such an awesome video! Great job! I love the video! You also did a great job on your LR3!

Finished my video. Added content to cover standard and custom struts, cuts and more. Hope this helps folks figuring out whether, and how to build their LowRider 3!

@vicious1, please let me know if I’ve inappropriately, overly misused V1E content.

Feedback appreciated, cheers!

Fantasitico! Still good with me using this as, THE, LR video for the instructions?

Thank you @vicious1, please use this how ever you want. This is my appreciation of the work you and others have put into this project. The current thumbnail is rubbish, I’ll work on that. I have the original slower realtime footage, happy to upload that if/when folks express that it’ll help clarify some of the build steps. Cheers!

Went nuts on the timestamped indexes. So why not hyberbole the pants out of the thumbnail too :slight_smile:
