@fcwilt so you're saying I can copy and paste your suggestion into the homez.g, correct?

As long as you make sure none of the existing code is there.

Or you can rename the existing file if you want to save it.

And then create a new homeZ.g file and paste what I posted into it.

@fcwilt So, I copy what's there from G91 to G30, delete that, then copy your code to that space to replace what was there, correct?

Doing that preserves the first 4 lines of code, and the last 6 lines as well.

Well if you wish to preserve those 2 or 3 first lines, that's fine.

But you don't need any code other than what I posted.

@fcwilt I just concerned that if I delete everything, then paste your code into that blank space, I'll loose the ; homez.g (header)?

It's not that I don't trust you, I've just never done any coding.

A Former User

@fcwilt okay, done

A Former User

@fcwilt on to Y, X?

A Former User

@fcwilt or should we test Z?

Just open the file, move down after the header lines, delete everything there to the end and paste what I posted into the blank space after the header.

Even if you did accidently delete the header lines you could simply type them in again.

; homeZ.g
; called to home the Z axis

@fcwilt or are they related such that we have to do all 3 first, then test?

A Former User

@fcwilt I see, but the header is in the list of files. it makes for a cleaner look, I think.

You can test homing Z and see if it works.

Then we will do X and Y.

Absolutely - I include headers and footers.

; === homeZ.g BOF ===

;  the actual code would go here

; === homeZ.g EOF ===

Just FYI, BOF is for "beginning of file", EOF is for "end of file"

@fcwilt so you write the code, but you don't put the line numbers in; that's what the program you write the code in does?

And the === before what you wrote, and the === after what you wrote create the idea of a "Header?"

The part at the top of the file is the "header"

The part at the bottom of the file is the "footer"

I actually put more than I posted into the header and footer - I was just posting a simple example.

@fcwilt link text

Here’s a link to the video of Z’s first attempt at homing.

A Former User

@fcwilt Z's going backwards. When I click on Z+0.5 it goes DOWN.

@mac @fcwilt you had the z probe working. Using an endstop on the low end is a retrograde step.

@droftarts hey, Ian, welcome to the show, what is a "retrograde step?"

Ian

In your opinion. I see it as a distinct improvement.

X and Y can be homed with no Z movement required.

And generally Z homing can be faster.

But that is just my opinion.
