The 'Black and Blue' LR3 build

I did it before school run

150mm left side - stopblock to X0
150mm right side stopblock to xMax

My spoil board is a little bigger as you can see

Thanks a lot, that helps a bunch. :slight_smile:

No problem

It is not included in the drawings because it is not a fixed point.

Your X endstop will dictate that.

Ah, makes sense. Helps anyway. :stuck_out_tongue:

Hey @Tokoloshe , importing the existing drawing into Fusion 360 calibrating for size help me answer some questions. Shared details here. Hope that helps!

Interesting. I use it on my LR2 and X is left/right arrow. I’m using keyboard control mode in cnc.js, that’s probably the difference.

Yeah, this is purely because of the way the ESP3D software award coded to do the translation.

As far as I know, the guy writing the ESP3D software has been looped in and has actually changed it.

And @azab2c actually did an awesome workaround that lets you/me remap any of the keys we want, which is cool

This is a super interesting thread. Thanks for sharing.

What are you using for software to generate the gcode for router and laser? Carveco?

Cool. BTW I just found your thread as I contemplate converting my LR2 to a 3. Great reading :slight_smile:

Thanks, I appreciate that!

Yes, correct.

I just couldn’t get a hang of Estlcam, plus I found a 3 month free trial for carveco and it’s very intuitive. So now I’m paying monthly, and all I need to do is make sure I sell 1 board a month to cover it.

And Lightburn for laser stuff. 2 week free trial, then an extra week, and a $60 one-off payment. It’s already paid for itself in how much extra personalization that you can do.

So, feb 13, I got Covid. Parents in law brought it in. Been a slog

I still have a couple residual issues that I’m working through, but I’ve been using down time to get ducks in a row. Business plan, YT channel plan etc

Anyway- I’m back. Hopefully doing an LR3 project on Friday- just a few carved boxes. They seem popular.

Glad you are back, since your tiny bee was the last nudge I needed towards the LowRider. I made some inlays and am really happy how they turned out. They are not as tiny as your bee, but the bee isn’t an inlay. :yum:

Ooooooffff

That sounds like a challenge!! I want to do a bee inlay now to prove it can be done.

I’m going back over your boom arm build. I’m thinking of doing a YouTube video on the LR3, and cutting the parts for the boom arm as the project. Although I may do a bee inlay now, instead. Or as well. Show the extremes.

That’s the spirit. :smile: Did I share all the boom arm files? I am going to check.

What did you use for your pivot pin, again? 1/4” rod or 1/2” conduit?

I’m debating actually just going with a single side, and not a box, and having the hose simply attached to the arm with zip ties or Velcro wraps. Would simplify both the actual arm and the mount build

I used 8mm threaded rods and nylock nuts.

I actually made plans for a shorter, extendable arm for the table itself but haven’t gotten around cutting it.

If you just use a single side you are losing a bit of stiffness, but not too much. There is s lot of maths involved and I am not very good at it. :smile:

Yeah, the reason I mentioned the single piece version is that there is a boom arm a YouTube woodworker mad a year ago, and it kinda went viral in the field- pretty much every new shop tour in the space has one. It’s basic, but no one has mentioned issues. Not a new idea but he he showcased it in his opening series of videos and it took off

I do like the box though, is much more substantial plus it contains the hose. I’m not a massive fan of the ‘hose ziptied to the side’ aesthetic

And a power cord (that I still have to install) and one more empty pipe for air if I ever buy a compressor. ;D
