Here's next week's video, early for Patrons, this one goes out publicly on Tuesday 12th.

Well it feels a bit like when I started building robot dogs, but here's part 2 ;-)

Ornithopter Part #2 - PREVIEW VERSION

I really want to do more flying projects. An ornithopter is something that flies by flapping its wings. There are various off the shelf kits available but I wanted to start from scratch and work my way through all of the development. You can support me on Patreon or buy my Merchandise: *************************** Patreon: https://www.patreon.com/xrobots Merchandise: https://teespring.com/stores/james-bruton *************************** Affiliate links - I will get some money of you use them to sign up or buy something: *************************** Matterhackers 3D printing supplies: http://www.matterhackers.com?aff=7500 Music for your YouTube videos: http://share.epidemicsound.com/xrobots *************************** Other socials: *************************** Instagram: https://www.instagram.com/xrobotsuk Facebook: https://www.facebook.com/xrobotsuk/ Twitter: https://twitter.com/xrobotsuk *************************** CAD and Code for my projects: https://github.com/XRobots Huge thanks to my Patrons, without whom my standard of living would drastically decline. Like, inside out-Farm Foods bag decline. Plus a very special shoutout to Lulzbot, Inc who keep me in LulzBot 3D printers and support me via Patreon.

There’s a Facebook group and everything: https://www.facebook.com/groups/287089964833488/ XROBOTS Former toy designer, current YouTube maker and general robotics, electrical and mechanical engineer, I’m a fan of doing it yourself and innovation by trial and error. My channel is where I share some of my useful and not-so-useful inventions, designs and maker advice. Iron Man is my go-to cosplay, and 3D printing can solve most issues - broken bolts, missing parts, world hunger, you name it. XRobots is the community around my content where you can get in touch, share tips and advice, and more build FAQs, schematics and designs are also available.

Nice, interesting seeing the design evolution process. I think you definitely need a bigger test area though ;)

Once it doesn't crash straight away I'll be taking it out of my garden ;-)

oo also broke a million subs! Nice!

Every time I print a pulley it goes out of sync with the belt. is there a minimum nozzle size for printing HDT pulleys?

XRobots

I'm just using a 0.5mm nozzle at 0.3mm layer heights. What are you using to generate the pulleys?

I import from McMaster-Carr in fusion, then edit the model and slice with cura. Iv tested on 2 printers and still get the same results.

Iv tried slowing my prints down but still getting a pointy tooth profile on the print. Dont worry too much about it tho lol. ill get to the bottom of it. Iv been printing for over 5 years and this just leaves me scratching my head. Think I will try tightening up my belts on the printer, thats the only thing iv not tried yet although the belts are not particular loose

I'm using a parametric SCAD file I found on Thingiverse for most of my pulleys, although the openDog2 pulleys were trialed-and-errored from scratch ;-)

Loving the choice of materials. The skeleton structure looks very steam punk, neat! If you have some spare mass you can lift would you consider skids or something to reduce stress when "landing"?

I'll think about that when it flies - I need to think about what happens if the motor moves back again because moving the battery forward to balance it any more will be tricky - so it may get some sort of under carriage.

My Hometown 4th of July parade might just need a "James Bruton" section! If you get this and OpenDog done it time LOL )

James, you have had several Lulzbot printers throughout your channel's history. Which one have you liked the best? I have a Taz 6 at the moment.

Michael Bigby

i wonder if you could get a little more reduction by using GT2 belts rather than the coarser belts. The minimum drive pulley size is determined by the belt pitch, right? Switching to a finer pitch belt might allow you to keep the second pulley the same size while decreasing the size of the drive pulley. 60:12 would give you 5:1 per stage with a largest pulley diameter of ~ 38mm. 12T might be a little tight for the belt, IDK...

I'm using Workhorses at the moment and I also have a Sidekick 747. I've never used any other make of printers but they all seem to work well for me.

I think printing them to work reliably might be an issues, I've never tried that small.

I think it would have to be significantly slower so that I could realise the full speed of the motor for the output speed I need.

Michael Bigby

I was thinking in combination with a higher ratio above. 25:16 * 800/1000 is a little more than half your current speed. To be fair if you need to be 5X slower this is pointless and you'll have to add the stage.
