reference the X-axis on both rails

Do you have the Z endstop sensor installed and ready to use? Good job.

OK as to the code...

Basically you use the same sort of G1 H1 commands that you do with X and Y axes.

The three files homeX.g, homeY.g and homeZ.g could end up looking pretty much the same.

To provide example code let's assume that all three axes home to the axis minimum. Let's also assume that the range of motion on each axis is a total of 300mm. The essential code would look something like this:

In homeX.g:

G91               ; relative moves
G1 H1 X-310 F6000 ; fast move to min endstop
G1 X20            ; back off a bit
G1 H1 X-25 F600   ; slow move to min endstop
G92 X###          ; where ### is the actual axis position when the motion stopped - usually determined by testing

In homeY.g:

G91               ; relative moves
G1 H1 Y-310 F6000 ; fast move to min endstop
G1 Y20            ; back off a bit
G1 H1 Y-25 F600   ; slow move to min endstop
G92 Y###          ; where ### is the actual axis position when the motion stopped - usually determined by testing

In home Z.g:

G91               ; relative moves
G1 H1 Z-310 F1200 ; fast move to min endstop
G1 Z20            ; back off a bit
G1 H1 Z-25 F300   ; slow move to min endstop
G92 Z###          ; where ### is the actual axis position when the motion stopped - usually determined by testing

Regards the G92 commands:

Remember that the G1 H1 moves stop when the endstop is triggered and the logical axis position is set to the min/max value from the M208 for that axis, depending on the configured location of the endstop.

But if your endstops don't actually trigger at exactly the min/max position (mine never do) then you can use G92 so the logical position of the axis (which G92 sets) is in sync with the physical position.

Hope that helps rather than confuses.

@fcwilt Thank you very much first of all... now I have to wait until the expansion board arrives (hopefully this week)... only then can I try it out and then report back... have a nice Sunday!
Cheers,

If I cannot help I am always happy to confused.

I just noticed a mistake in my example code the F letter was missing from the slow moves speed setting. I just corrected them.

@axiom for displaying code in posts, please use the code tags. It’s the </> icon on the toolbar above where you type in your post. It should put 3 tick marks at the beginning and end of your code. It makes it much more readable for people trying to help you. Single tick marks either side of text make that text inline code, like this.

What expansion board are you using?

On my 3 Z stepper printer I am using Duet 2 boards: Duet WiFi and a Duex5.

My M574 for the Z endstops looks like this:

M574 Z1 S1 P"!duex.e2stop + !duex.e3stop + !duex.e4stop" ; configure active-high endstop for low  end on Z

The Z endstop sensors are connected to the Duex5 and I included the duex. prefix. I recall that it was necessary.

Frederick

Phaedrux

@axiom said in reference the X-axis on both rails:

M574 Z1 S1 P"e2stop + e3stop + e4stop + e5stop"

If you send M98 P"config.g" you'll probably get an error saying invalid pin or something like that for that line.

droftarts

@fcwilt as @Phaedrux says, the pin names are wrong. See https://docs.duet3d.com/Duet3D_hardware/Duet_2_family/DueX2_and_DueX5#pin-names

Should be duex.e2stop etc.

Ian

@droftarts
I have now adjusted the names, but the endstops are still not accepted. Here is the message from the m119 command and the M98 P"config.g" command. And below again my adapted code

M98 P"config.g"

HTTP is enabled on port 80

Error: in file macro line 50 column 65: M574: string too long

m119
Endstops - X: at min stop, Y: not stopped, Z: no endstop, Z probe: not stopped

All control LEDs respond...The 4 motors on the expansion board react and can be controlled

I think it's not a hardware error it is a DueX5 xspansionboard

Did you try shortening the line? I believe the comment is included when it comes to being too long.

And you can remove the M501 at the end if you wish to silence the error about config-override.g being missing.

Frederick

droftarts

@axiom What firmware version are you on? This has come up before, and it's because the string for the endstops is too long. See https://forum.duet3d.com/topic/32954/duet-2-wifi-voron-2-4-multiple-z-endstops-query
This was fixed in RRF 3.4.6, with an increase from 50 to 61.

However, I think you just need to take out the spaces in yours to get under the 50 character limit, ie

M574 Z1 S1 P"duex.e2stop+duex.e3stop+duex.e4stop+duex.e5stop" ; configure switch-type (e.g. microswitch) endstop for low end on Y via pin ystop

That's 47 characters.

Ian

@droftarts Deleting the spaces was the solution...it no longer gives an error
message and the g1 h1 z0 command works and the bed stops at the endstops...now I can continue researching! Thank you so much!!!!

@axiom download "Duet2and3Firmware-3.4.6.zip" from https://github.com/Duet3D/RepRapFirmware/releases/tag/3.4.6 without unzipping it, then upload it to the Duet. It will unpack it and install the firmware update.

There's a whole wiki page on firmware updates: https://docs.duet3d.com/User_manual/RepRapFirmware/Updating_firmware
