Canadian lr3 build

Starting the assembly stage.
Skrpro1.2
1” od (25.4mm ss tube 80.00 for 20’ CAD) I already had it eitherwise I would have done emt.

18mm od emt tube for long rail

1/2 plywood xy plates milled on mpcnc
Tried milling 6061 plate but I am not ready for that yet.

Qty 2 3/16 pieces of acrylic per side for xz plates.

4’by8’ build
I made a boo boo and printed my gantry triangles in 20%
For the end ones I went 50% I am wondering if I should reprint them ?

I am just waiting on steppers and linear rail.


Thought I would start a build thread bc I am sure I will need to grab some help.
Cheers

And you‘ll get it. For me it‘s mostly about documenting my journey and letting you all take part in it. :slight_smile: So a build thread is always a good idea.

It´s looking good and I like the color scheme!

That core is upside down… the wide end goes top, narrow on the bottom.

Looking good otherwise.

Thanks it kinda just happened using up filament.
Soon the fun begins.

Haha didn’t even realize thanks
Had it all there figured I should see if it rolls on.
The new inverted air cutter

Could you write something about how you printed the parts? Infill pattern? Nozzle size? Layer height? Bed temperature? Nozzle temperature?

I used the same settings I used for my MPCNC, except for the infill which I took from Ryan’s recommendations for the Lowrider. :slight_smile: You can find them here: MPCNC Primo Schneewittchen - Oldenburg, Germany - #152 by Tokoloshe

Honestly I leave most the setting alone.
I am using a ss .5 mm nozzle 250deg
Pla +
70mm sec
And I follow the infil that v1 has lid out.
Minus my brace mess up
I think most prints call for 35 I went higher for my mpcnc
I have a elegoo pro basically stock
Basically what Phillip said haha

.
i see it’s says I need 8 braces for the gantry.
It seems like I should have 9 almost for the full sheet build.
Is the spacing just setup like this for the initial temporary build to cut the long gantry brace ?

Yes, the braces on the sides are closer together for cutting the strut plates close to the edges, after you cut the plates they will be evenly spaced.

Thank you :slight_smile:
I hope you have a great Friday and may your bits stay true.

I had this weird idea, I am sure it has been done but I wanted to see if I painted acrylic with a shiny silver paint. And if I polished the edge and used some led of the light would be directed nicely on the opposite edge.
I really liked that
AzA guys ruler gantry brace and wanted to use acrylic for it and use this method with end lighting it.
Then I saw that the lower gantry tube would block the light :(.
But I guess it could still be neat for lighting the measurement increments up.


Some minor progress I just about have all the parts now.

Looking good!


Linear rails now, and I think I have all the parts to finish now.




Gantry on now!!
But it looks sad

Small wire update also had to shave the heads off some cap screws as I didn’t buy the kit from Ryan and there is a couple space issues.
I must say when I say the hole for tie wraps in the core I was like no it can’t be and sure enough yep it was haha very neat design and well thought out.
Now I need to do some belts, and figure out what to do for power supply.
Wondering if I should put some RC connectors on my 24v power supply I use for the mpcnc or just use a old laptop charger at 12v kinda leaning toward the laptop power supply.




Ok so I am almost at the crown stage.

You got the holders for Y the wrong way around. :slightly_smiling_face:
