GP - LR3 Beta Build

That is great news. Nothing like the first moves.

Maybe that area begins could be used to store the gantry. How long can you get drawer slides :slight_smile:

I have been looking at your build to try to figure out how some of these parts go together. It’s been very helpful. Thank you for the vid and pics.


Oooo, that is cool to see.


Today I finished the wiring management, well at least until I have the Strut plates, I used some wire sleeves range from 1/4" to 3/4" for the big loom that comes from the YZ-2 side.

For now, the power supply is tucked inside the braces, tomorrow once I have the strut cut I will figure it out where the power supply will go, I’m planning to add an AC/DC Control Relay to start/stop the router and vacuum at the same time, I still need to look at the firmware part of it.
And finally we have full motion… I ran it at, 3500mm/s for the video.

Tomorrow is the day, I can’t wait to have it making chips!!


Oh man, I can’t tell you how awesome that is to see. I swear I caught myself thinking…I want to make one of those! WTF!!!@?! As long as the performance is legit I think we are making a real winner here.


I do believe you did! The machine is awesome. Can’t wait to see it full assembled and making some real dust.

Well I screw up more than once today, was able to cut 2 out of the 3 struts… Cut a piece of plywood 300x1450 and let’s get the machine dirty!!!
I didn’t check the router bit, as it was used to cut the YZ plates and I had no burns or any other issue, looks like it was the best Bit, so start the cut and this happens…

Then I Realize that I was also going a little too fast, well the same speed I cut the YZ plates 20mm/s.
Changed the end mill, drop the speed to 12mm/s and got 2 struts cut.

Watch and see how much dust is all over the table :wink:
The Dust chute that Ryan design works great!

Then was time to take the LR3 apart and install the struts, sorry I didn’t take any pictures of the LR3 totally apart but here are some of the rebuild with the new struts.

And that is when I realized my second mistake…
The plywood was a little too thick…

So the X belt tensioner does not clear the core as it bends a little, but just enough to hit the core. :sob:

Well… Tomorrow I will take the front strut out, back to the big orange store, get a thinner plywood and cut one more strut. The good thing is that I do believe I can use this thick strut on the back of the machine.
We will see…


Just sand it down right there a bit, no big deal. It is hidden behind that tensioner.

Normally with my screws, the heads would hit before that part would deflect.

Sorry For the lack of update, What was supposed to just be a weekend event in DC end up been a full week of video shoots for CVS Health. I will be back home tomorrow afternoon and I will finish everything on Saturday. All parts are printed and I’m planning to use the 6.35mm struts that I had cut for the first try.
I think it will take me just couple hours to rebuild it.

Had edited the post… I hate replying on my phone

No, no rush. Sorry don’t feel that way. I just thought I might have missed it in the other thread or something.

I am still waiting on rail samples and some custom T8’s


I think I should post some more pictures that I share over PM with the beta crew… And update the building thread.

Acrylic plates are ready!!
I forgot how painful it is to peal the paper out of the acrylic :hot_face:


Little progress today.
But was able to cut the strut the acrylic plate and rebuild one side of the YZ.

Tomorrow I will rebuild the other side and reinstall the belts.
Nothing wrong with the screws or lock nuts but I’m going to order some M5x25 and some back lock nuts just to make it look prettier :wink:

Now I’m wondering how can I mount some Neopixel to lid the edges…


It’s a looker for sure!!

First real project for the LR3.

The wife wanted to buy 5 Adirondack chairs to go around our Fire pit. I said NO…I will make them…

Spend the last couple nights designing the chair, and today I start milling the parts.
Here is a screenshot of the design, I added a slot to hold a wine glass and a hole for a regular glass or a beer cam which I’m not sure if will a hole or just reassess in the wood (haven’t decided yet) and I still need to add a brace to the front leg.

As The top back support has a chamfer, I decided to start on that part as it has a couple of tool changes.
Here is a short video ( 36s ) of the LR3 dancing as it makes the chamfer.
Edited: Lower your speaker volume!!! It is Loud !!!



Well, work got in a way again. But I was able to cut and get one chair together….

Chair Kinda in place ….

And …… the wine glass and drink/beer holder


That acrylic is awesome!


Do you use a steel ruler as your z probe?

Yes and no :smile:
I have Ryan’s V1 touch plate, the reason for the ruler is that I was using it on the LR2 and the touch plate is a little to short for the Lr2. That particular ruler is 0.5mm just like the V1 touch plate.
