@fcwilt Z must be wrong, don't you think?

fcwilt

@fcwilt with X depressed, X is at min stop, everything else is as it has been.

With Y depressed, Y is at min stop, everything else is as it has been.

Fantastic.

So we know the X and Y endstop are working.

But the Z is not. It should do the same as the X and Y.

Please do this - from the DWC console execute M574 by itself - it should report how each endstop is configured.

@fcwilt something about that doesn't look right?

Great. You getting the hang of this, aren't you!

So it says the Z endstop is configured on the low end, is connected to io2.in and does not have the ! character because the white wire is connected to the NO connection on the switch.

But it seems that pressing or not pressing the Z endstop switch doesn't change what M119 reports.

Did you verify that the Z endstop switch is still plugged onto the IO2 connector?

@mac are you sure z endstop is connected to io2? Check with wiring diagram. https://docs.duet3d.com/Duet3D_hardware/Duet_3_family/Duet_3_Mini_5+_Hardware_Overview#wiring-diagram

@droftarts hey's baaaaaaaaaccccccccckkkkkkk

I just moved the white wire on the 5 pin io2 connector from io2_out to io2_in, The green wire is still in the center of the connector / connected to GND.

Well that certainly should make a difference.

Please run the M119 tests with the Z endstop switch pressed and not pressed.

@droftarts @fcwilt M119 reported all of the axis are NOT STOPPED, WAIT A MINUTE!!!!!

6/27/2022, 9:28:48 AM	M119
Endstops - X: not stopped, Y: not stopped, Z: at min stop, Z probe: not stopped
6/27/2022, 9:28:11 AM	M119
Endstops - X: not stopped, Y: not stopped, Z: not stopped, Z probe: not stopped

Look at the timecode, between :11 and :48 Z changed!

@droftarts @fcwilt I knew there was a reason I named this machine Frankenstein's Cinderella.

So it seems like the Z endstop switch is now working?

@droftarts @fcwilt I turned off the machine, then turned it back on. M119 reports that Z is at min stop.

My finger isn't anywhere near it.

But, when I depress Z, and send M119, it says Z NOT STOPPED.

@droftarts @fcwilt Z needs to be reversed, doesn't it.

Just edit the M574 line for the Z endstop and add the ! character, save, re-boot and re-test with M119.

You see what X and Y endstops do.

You need to get Z doing the same.

@fcwilt @droftarts FREAKIN' SUCCESS!

With all of the endstops up, all of them are off, with Y endstop depressed, it is at min stop. with Z depressed, it is at min stop, and with X depressed, it is at MIN STOP!

A Former User

@droftarts @fcwilt I wonder where that puts us?

Congrats.

Now that you know the endstops are working you can proceed to fine tune your homing code.

Because you have a Z endstop you can start with that.

One Z is homed then homing X and Y is a piece of cake.

How about doing one at a time.

Please post your Z homing code which should be in homeZ.g

@mac

OK that is code for homing with a Z probe.

Now that you have a working Z endstop you can use simpler code.

Something like:

G91               ; relative movements
G1 H1 Z-250 F3600 ; fast move toward Z endstop
G1 Z10            ; backup off a bit
G1 H1 Z-15 F360   ; slow move toward Z endstop

G90               ; absolute movements
G1 Z10 F3600      ; move to 10mm off the bed to allow X and Y movements

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