Can not home z and y

Hi My printer is a Cartesian, and here is my homeall.g

G91 ; relative positioning
G1 H2 Z5 F1000 ; lift Z relative to current position
G1 H1 X-1005 Y-505 F1800 ; move quickly to X and Y axis endstops and stop there (first pass)
G1 H2 X5 Y5 F1000 ; go back a few mm
G1 H1 X-1005 Y-505 F360 ; move slowly to X and Y axis endstops once more (second pass)
G1 H1 Z-505 F360 ; move Z down stopping at the endstop
G90 ; absolute positioning
G92 Z0 ; set Z position to axis minimum (you may want to adjust this); Uncomment the following lines to lift Z after probing

@Finnls this looks ok.
If you trigger the endstops manually (with the finger), does it show triggered correctly, for the right axes?
-
Yes the do.
G1 H1 X-1005 Y-505 F1800 - do not move y
G1 H2 X5 Y5 F1000 - do move yI have run homeall.g ono by one in console

G1 H1 X-1005 Y-505 F1800 - do not move y
what do you mean by "do not move y", it only moves X? With cartesian, both axes should move until both endstops are hit. Like described in https://duet3d.dozuki.com/Wiki/ConfiguringRepRapFirmwareCartesianPrinter#Section_The_homeall_g_file
But you can test split command of course:
G1 H1 X-1005 F1800
G1 H1 Y-505 F1800The M574 S1 with ! means normally open switches, is this correct?
-
When I send G1 H1 Y-505 F1800 - Y moves between 1 to 6-7 mm and stops.
But Y is 0.0 in status.
My endstops are micro sw 2wire, one to gnd, and one to in
-
@Finnls looks like the Y endstop is activated immediately, maybe it's of type NC (normally closed) and you need to remove the ! in the M574 for Y.
Or a disturbing signal closed the switch immediately, please try moving the endstop wires with a little distance to other wires. (That's the reason why NC is recommended).
Or the printer vibrations trigger the endstop.
The Y 0.0 is a hint that the y endstop was triggered, because G1 H1 mode stops at the endstop and sets Y to the M208 limit, which is 0 in your case.
-
Not vibrations, but disturbing signal, I think you are on to something - maybe i need a resistor between in and 5v

Sorry I did not seen that - i can make it to NC. I will do that - Thanks

you would not need it, Duet 3's io.in have already pullup resistors:
https://duet3d.dozuki.com/Wiki/Connecting_endstop_switches#Section_Duet_3_endstop_inputsBut I expect using NC will solve the issue.
-
Thank you JoergS5 it is solved
-
@Finnls I'm pleased, thank you for confirmation!
