@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

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.

@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!!!!

Can I just click on it here, or do I have to prepare something?

droftarts

@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

@droftarts Is there something to update for the Due5 expansion board...or is that okay?

@fcwiltI have now adapted the home files according to your stage directions (see below) and removed the homeall.g as you said. when I click the reference button on the user interface , the error message comes up:

Now I don't know what homeall.g should look like?

Here are my new homing files:

@axiom

I don't recall saying to remove the homeALL.g file.

What I think I said was I don't duplicate homing code so my homeALL.g file looks something like this:

M98 P"homeZ.g"
M98 P"homeX.g"
M98 P"homeY.g"

The results are the same but there is no actual "homing" code in homeALL.g.

Frederick

fcwilt

@axiom

And since you now have Z endstops you don't need to use the type of homing code the configuration tool generates.

I also suggest you work towards not using the configuration tool and learn how to create your own code.

Your code will likely be better and fixing code related problems will be easier since you fully understand what you coded.

Didn't I post examples of what your basic homing files would look like?

Basically you do:

a fast G1 H1 move toward the endstop
a short fast move G1 move away from the endstop
a slow G1 H1 move toward the endstop
a possible G92 to set the logical position of the axis being homed to match the physical position

Assume a printer where the X endstop is at the min end of the X axis and the axis has a range of motion of 300mm:

G1 H1 X-310 F6000
G1 X20
G1 H1 X-25 F600
G92 X=nnn ; where nnn is actual position of the X axis after the 3 moves above

I'm just stuck...if my z-endstops are set to 4 and I want to reference...but the bed is already above the end stops, e.g. 2...then the bed moves into the head. So I currently have to move the bed below the endstops before referencing...how can I correct this in the z-home. Here are my files again:

@axiom

You have to design the mounting of the endstops so they are triggered to the very end of travel.

MFx Z AXIS ENDSTOP.jpg

Here you can see part of the Z axis setup on my tripple Z stepper printer. The endstop switch is activated by the side of that bracket that is supporting the ball stud. The bracket travels along the linear rail. The endstop switch is first activated well before the end of Z travel but remains activated to the very end of travel.

So you cannot move "past" the endstop.

Let's suppose you use a typical bit of homing code like below:

G91
G1 H1 Z-300 F1200
G1 Z50
G1 H1 Z-55 F300

If you start with endstop already activated the first G1 move doesn't actually move and the code continues doing the backup move and then the slow move to endstop.

Some folks include a test to see if the homing code starts out with the endstop activated and if it is the code backs off enough to insure the endstop should no longer be activated and if it is still activated they abort the homing and display and error message.

That "safety" check is a pretty good idea.

Frederick

axiom

@fcwilt but you wrote to me that if my endstops are further down, then I can simply define the position, e.g. 4, with the G92 command... I need the information on how to automatically go deeper than 10 mm when referencing ...when it starts up it encounters the endstops...is the G91 command at the beginning perhaps wrong?

fcwilt

@axiom

You can use G92 to sync up the logical position with the actual physical position.

But if you can move past the endstop until it is no longer triggered you would have to insure that every Z homing operation began with a relative move to be sure you were no longer past the endstop. And that move could cause a problem if you happened to be near the max end of travel.

As you can see I deal with that problem by insuring that endstop can be triggered all the way to the end of travel regardless of where it is initially triggered.

Frederick
