Ender 5 + Duet wifi starts on wrong side g29

@lui2004
Don't forget to change all the problems motor direction , end stops and home files plus not minus.

Does to crash into the correct end stop , eg right back ?
Use M119 to get the end stop status , and check if the end stop is working before homing .

The ! on the end stop , is the switch trigger on normally open or closed , So that may differ , it all depend how you have wired it.

M119

i have changed it all but it crashes in right back.

M119
Endstops - X: not stopped, Y: not stopped, Z: not stopped, Z probe: not stopped

can you help me for home files ?

peter247

@lui2004 o.k , manually home it , eg trigger all the switches and do a M119 ?
How do the opposite , moving the head from all the switches and do a M119 again ... any difference ?

One command which may help you is : M84 x y z , switch off all motors.

I don't think you have set up the btlotch yet , so you will have problems with Z homing , but lets get your X , Y end stop switches working first.

M569 P1 S1 ; Physical drive 1 goes forwards

homeall will try to trigger on left front instead of right back

@lui2004

Z axis will crash in the bed also

; homeall.g
; called to home all axes
;
;G28 XY
G91               ; relative positioning
G1 H2 Z5 F6000    ; lift Z relative to current position
G1 H1 X 355 F3000 ; move quickly to X axis endstop and stop there (first pass)
G1 H1 Y 355 F3000 ; move quickly to Y axis endstop and stop there (first pass)
;G1 H2 Z-5 F6000   ; lower Z again
G90               ; absolute positioning
 
G1 X125 Y175 F4000 ; Move probe to middle of bed
G30

This is my home all file , very simple but it works .

G91 set relative , which means move eg move 5mm plus , not to position 5mm.
G1 H2 Z5 F6000 , which means move up 5mm

Now this is the part you have wrong !!!

G1 H1 X 355 F3000 , move right ( not left ) until you hit the end stop
G1 H1 Y 355 F3000 , move the head back until you hit the end stop
G90 ; absolute positioning again

Next problem

G1 X125 Y175 F4000 ; Move probe to middle of bed
G30 , use the BLTOUCH to home not any end switches .

READ THE LAST POST is their any difference between homed and not homed with M119 ?

lui2004

m119
Endstops - X: at max stop, Y: at max stop, Z: not stopped, Z probe: not stopped

i cant home my axis it will crashes every time i change it in config

So that is when homed and you are X and Y not stop if not homed ?
Have you copied my homing all file ? and changed the motor direction .

lui2004

not all

only setup for :

Endstop,motor drive

peter247

@lui2004 X and Y , Z motor should be the same ( MUST ) , But E could be any direction , that is a suck it and see.

O.K , lets make a macro and see if we are on the same page.

Move the head it middle of the bed and try.

G91
G1 H2 Z5 F6000
G1 H1 X 10 F3000
G1 H1 Y 10 F3000
G1 H2 Z-5 F6000
G90

Does it move to the right and too the back 10mm in each direction ?

If it doesn't change the motor direction until it does !!!!

lui2004

the macro will only move the bed up and down

peter247

@lui2004

O.K to safe , it looks like you can see a 10mm change .

G91
G1 H2 Z5 F6000
G1 H1 X 100 F3000
G1 H1 Y 100 F3000
G1 H2 Z-5 F6000
G90

This should lift the head up , move right and to the back 100mm now.

only z moves up and down few mm

but x and y dont moves

peter247

@lui2004

o.k confirm this :- After you run the macro and it goes up and down , does it say homed X an Y ?

lui2004

yes after i run the macro it move only the z but x and y was homed

peter247

@lui2004 o.k wiser .

; Endstops
M574 X2 S1 P"!xstop"    
M574 Y2 S1 P"!ystop"

So have you changed this and what too ?

lui2004

yes i have changed it

peter247

@lui2004 With the ! ?

lui2004

yes with the '!'

peter247

@lui2004

O.K , I'm hoping you are doing this which the head in the middle of the bed ?

Try removing the ! and try running the macro again.

lui2004

it will move now with '!'

but the origin 0,0 back right the webinterface showa me back right 235,235
