@fcwilt Ok what about when I use my Z-Probe and to run G32 how that going work

@fcwilt Ok what about when I use my Z-Probe and to run G32 how that going work

The changes I suggested were only for TESTING to verify that each Z stepper on it's own was working as expected with no possible interactions with the other Z steppers.

Once you were sure that they were working then you would restore the original stepper configuration commands.

Ok make sense thank you

M574 Z2 S1 P"!exp.e2stop+!exp.e3stop+!exp.e5stop+!exp.e6stop"

Instead of using exp.e#stop let's try using the pin names for the actual deux pins.

duex.e2stop
duex.e3stop
duex.e4stop
duex.e5stop
duex.e6stop

When using these names I think you can remove the !, but please test carefully.

moe.adams9093

@Phaedrux so I did move the ! And did exactly as
M574 Z2 S1 P" duex.e2stop+ duex.e3stop+duex.e5stop+ duex.e6stop"; when I click home Z axis are not moving they do get power but no signal

Phaedrux

And if you check M119 what does the endstop status say?
If it says the z endstop is triggered but the switch isn't pressed, then you would need to add the ! again to invert the signal.

moe.adams9093

@Phaedrux yes thats what I got

2/1/2021, 1:30:18 PM: M119: Endstops - X: not stopped, Y: not stopped, Z: at max stop, Z probe: not stopped

moe.adams9093

I'm going to put ! back and see what's going on

moe.adams9093

The only one is communicating probably is e6stop

moe.adams9093

Its not working. when I added this code
M574 Z2 S1 p"!duex.e6stop+!duex.e5stop+!duex.e3stop+!duex.e4stop";
and run M119

M119
Endstops - X: at min stop, Y: at min stop, Z: no endstop, Z probe: not stopped

but If I remove any one of any of the above endstops

example:
M574 Z2 S1 p"!duex.e6stop+!duex.e5stop+!duex.e3stop";

my M119 will show Z end stop is available I don't know what's causing this issue to not take all 4endstops. also when I press any of the endstops they all stop automatically not individually. I don't know whats happening maybe my duex 5 is bad or if you guys know any solution around please let me know. thank you

I believe somehow some of my end stop input on my duex 5 is not responding correctly. can I use stall detection to stop each motor at Zmax. please share your thoughts

@dc42 I hate to jump in and be an idiot, but is it because MaxAxes is set to six in the firmware?

I have the same board setup as you - Duet 2 WiFi + Duex5.

On my printer I only have 3 Z steppers so my end stop configuration command is:

M574 Z1 S1 P"!duex.e2stop + !duex.e3stop + !duex.e4stop"

As an experiment I entered this on the DWC Console

M574 Z1 S1 P"!duex.e2stop + !duex.e3stop + !duex.e4stop + !duex.e5stop"

and got this error message:

M574 Z1 S1 P"!duex.e2stop + !duex.e3stop + !duex.e4stop + !duex.e5stop"
Error: M574: Unknown pin name 'duex.e5sto'

Notice the last character, the p, is missing.

I then took that same text and created a gcode file with it in my sys directory.

I executed the file with the M98 command and got the same error.

I then used this text to create another gcode file with it in my sys directory:

M574 Z1 S1 P"!exp.4 + !exp.9 + !exp.14 + !exp.19"

which are alternate names for the pins.

I executed the file with the M98 command and got NO error.

Then I executed from the DWC console a M574 and got this:

Endstop configuration:
X: low end switch connected to pin xstop
Y: high end switch connected to pin ystop
Z: low end switches connected to pins !(exp.e2stop,exp.4) !(exp.e3stop,exp.9,spi.cs6,duex.cs6) !(exp.e4stop,exp.14,spi.cs7,duex.cs7) !(exp.e5stop,exp.19,spi.cs8,duex.cs8)

Notice for Z that all four pins are now present - albeit with all possible names for each pin.

It looks like there may be some sort of command length limitation causing the problem.

I tried this test with both 3.1.1 and 3.2.0.

Try the alternate names and see if they work for you.

@fcwilt Do you get the same error with the original pin names he had used?

M574 Z2 S1 P"!exp.e2stop+!exp.e3stop+!exp.e5stop+!exp.e6stop"

Hold on and I will try.

It shouldn't because in RRF3 you can use multiple endstops on a single axis. No need to create additional axis anymore.

That works.

@fcwilt Hmm, wonder why it didnt work for him the first time?

I have no idea - this topic has gotten rather long and it's hard to remember it all.

Those names you suggested are shorter by one character each which tends to reinforce the idea of a command length limitation.

Perhaps you could speed verification of this possibility with direct communication with dc42?

Yes. M574 Z2 S4. But you'll have to do the usual stall detection tuning.
