@Veti i am using 3.1.1 (2020-05-19b2).
Thank you for the link. this is definitely helpful.

"ystop=e1stop"
That should be a + not an =

also you might want to switch to cnc mode

I fixed it !!. my endstops were on NC, I put a ! in front of it to make it a NO and now it works
I used the normal code for the home command and the M574 in my config.I found this other forum post from a guy with a similar problem. https://forum.duet3d.com/topic/20318/mpcnc-duet-3-sbc-dual-endstop-for-x-and-y-axes?_=1609092505581
And I read from this link https://duet3d.dozuki.com/Wiki/Bed_levelling_using_multiple_independent_Z_motors#Section_In_RepRapFirmware_Num_3
that @Veti provided that in 3.0 and above you don't have to separate the axis.Thanks, @Phaedrux for noticing my error in the code, that would probably have taken me a day to figure out.

Hi
Can someone help mi with problem i have?
there is something wrong with my homing Y.
I do homig, steppers are moving, they both hit endstops, move back a bit, but then, only one on my steppers is going to hit endstop (Zstepper is triggers zstop).
Ystepper is not hitting the endstop. LED on mb is not lid.

Remove the H2 on those moves in your homing files. It's ok on the Z axis.

G1 H1 X-235 F1800 ; move quickly to X axis endstop and stop there (first pass)

You need to increase the distance of the first homing moves. They must be longer than your axis length.

M584 X0:3 Y1:2 Z4 P3 ; set drive mapping
Why do you have P3?

@Phaedrux said in how do i do dual endstops for X and Y axis on my cnc:
Ok, removed H2 and increased the distance in both home.g files. Thanks.
But nothing changed, X homing OK, Y does not.Why do you have P3?
Isn't that P3 to show those 3 axes? To home them and move them?

You can leave the P3 off entirely. It's mainly used for when you have multiple temporary axis like UVW. You're not doing anything like that since with RRF3 you don't need to split up the axis for homing anymore.
What exactly happens with the Y axis when you do homey?
Does it move in the correct direction towards the endstop?
Does it stop before it hits the endstop?
If you click the endstop by hand while it's moving does it stop the axis? -

when i try to home Y. Steppers are moving, direction is ok. They both hit endstops, if misaligned stepper that did not hit the unstop is mooving until he does hit endstop. Then they move back together, and together in correct direction moving lowly towards endstops. However only one endstop is triggered and then steppers stops, homig ends as homed. -
@shante Can you send M98 P"config.g" in the console and report the response?
M574 Y1 S1 P"ystop+zstop" Do both endstop LEDs work correctly when you manually click the switch?
-
@Phaedrux they do, if tested manualy and in first homing pas. After second pas, that slow approach, only one is triggered, Ystop, and Zstop is not. Stepper do not come close to trigger it, its like 0.5mm away.

So they are aligning properly on the first pass until both endstops are triggered, but not on the second pass?
Can you make a video showing what's happening?

Yes, exactly.
No video yet, as im rewiring endstop and stepper. Tried replaced endstop, no joy.
New wiring will be with yet another endstop, we will see.Do i need to split steppers if adding offset to one of steppers will be needed?
If so can you write me example code how to do that? -
@shante Some videos/photos of the setup would help to understand what's going on.
-
After rewiring(new wires for stepper and endstop) and new endstop, issue is gone...
Thank you @Phaedrux for your help and patience with me.
