Status on Lowrider 4

My LR4 is Finished,I have make a short video to show You my custom setting.

FIRST OF ALL
this is not a complete tutorial, I’ll do it later, and all this features NEEDS modification in the config file, like Soft Limits, Z mpos value etc…
All the movements and features works with Machine Coordinates, so You can’t use “G92” zeroing method anymore(unless You know what You are doing), instead you have to use G10 or the “Ø” on WebUI. In this way you will have two(at least) coordinates systems:

  1. Machine coordinates, given by homing and config settings.
  2. Workpiece Coordinates (G54-59), set by G10 or Ø button.

By default the machine moves relative to Workpiece.
Typing G53 before EVERY command line ( ex. G53 G0 X100 Y200) the machine will move relative to Machine Workspace.

This is only a quick explanation, for new users there’re a lot of things to learn before. At the beginning it’s better to follow Ryan’s documentations and suggestions, they’re easier and you can start faster.

That said, I added a 4 input I/O module to the spare slot of the Jackpot Board, and modified the config file:

The config file relative to this mod will be like this:

The macros are wrote directly inside the Config, no external .txt (pay attention, this create conflicts with V1E’s standards Macro).
The macros I create are made to work in every position of the machine, you can start probing at whatever Z position you want, the only limits are the real travel of the machine. The same is for clearing the workspace, it doesn’t consider the starting position and workpiece coordinates.

And this is the result:

This is the cable managment:

That looks amazing! What do your y stops look like? I’m most of the way done but the documentation isn’t ready yet so I might be able to figure it out if you have a picture!

I’m not in the workshop anymore, but anyway I placed them without any advice, so would be better to wait official documentation for a proper assembly.:sweat_smile:

Congratulations, and great build!

Thank you for sharing these details.

Do you have a build thread for your machine?
I probably sound like a broken record- but this great information will get buried in a sea of posts here in the status thread and that’s a real shame.

Your great work deserves to have a build thread that we can refer to and learn from as you continue with your machine.

If and when you have a chance to do so instead of screenshots of configs, posting it here as preformatted text also helps folks trying to follow in your footsteps.

Again, great work and thank you for sharing!

So you have 4 buttons are 2 gpio.14 and gpio.13 and 2 are the macros?

And that webpage, did you create it?

Definitely want to see a build page, pls!

The new LR4 has openings for limit switches on both ends of the YZ plates and both sides of the core, and has end stops built into the belt tensioners on both ends (and ability to home X to either direction)! The stock configuration is to use only one set of those, homing at X min and Y min, but homing at X max and Y max is doable, and @Rico_LRS loaded limit switches into all the unused empty slots too!

I also tested Hard Limits, they work as aspected, i the machine hit the limit switches It stops immediately and gives an error

4 gpio : 14, 13, 12 and 15.
There is also the 39 still free, but I’m leaving it unused for future needs.

I more meant like where the belt attaches, the new design was confusing me because it’s so small maybe?

1277

Yes, I will definitely do it in the next few days, this was only a quick overview made for @DougJoseph and another guy who asked

They are wrapped around a M3x10 screw and slided inside

The “front” (min) belt tensioners are “holders” only, while the rear (max) belt tensioners have screw-adjust tension deals built in. Both ends have little printed parts the belt goes into, wraps around an M3 screw, and then feeds back in. When it gets pulled in, it brings the screw in, where it gets captured and ensures the belt cannot slip out.

The M3 is used like an holding pin.
All the belts locks in this way, on both sides

Very nice! Now you just might need a fancy WebUI v3 theme for your fancy machine. :wink:

I need the V1 theme but with light brow instead of red, to match the machine :joy: :sunglasses:

To work with a dark theme, it needs to be a darker brown…

It’s pretty easy to mess with colors since they’re defined at the top of the CSS.

/***** COLORS *****/
:root {
    --primary: #5c0000;       /* Primary Color - Header Background */
    --secondary: #7c1006;     /* Secondary Color - Panel Header */
    --bkgd: #090909;          /* Page Body Background Color */
    --panelbkgd: #212121;     /* Panel Body Background Color */
    --buttonbkgd: #3b3b3b;    /* Button Background Color */
    --highlight: #ff0000;     /* Selected/Active Color */
    --logo: url("logo.png");         /* Logo on Flash - 30px height, max 250px width */
    --logosmall: url("logo-sm.png"); /* Small Logo on Flash - 30px height */
}

I just realised I printed the wheels at 15% infill. It 20% :frowning:

X min side probably won’t matter. X max side may.

How important is the 2mm gap in the xz-min plate? I don’t have an endmill that small so wondering if i can just mill the rest and slit that part with a grinder/dremel? I assume it’s designed to feed cables through?
