@OwenD Thank you for clarifying that, it really helped! And since I have a duet 0.8.5 I cant use the RRF3...

@Phaedrux Hi and thanks for reply! I am not after a mesh bed leveling.
My gcode looks like this at start

G90
M83
M106 S0
M140 S65
M190 S65
M104 S235 T0
M109 S235 T0
G91       ; set coordinate system to relative mode
G1 Z3     ; lower z axis 3 mm
G90       ; set coordinate system to absolute mode
G28       ; home all axes
G1 Z4     ;lower z axis 4mm
; process CoreXY-PETG
; layer 1, Z = 0.200
T0
G1 E-4.0000 F2400
; feature skirt
; tool H0.200 W0.400
G1 Z0.200 F1002
G1 X167.920 Y169.840 F3000
G1 E4.0000 F2400
G1 X168.463 Y169.327 E0.0223 F1920
G1 X169.889 Y168.102 E0.0563
G1 X170.377 Y167.716 E0.0186
G1 X171.473 Y166.917 E0.0406
G1 X171.884 Y166.637 E0.0149
G1 X172.977 Y165.942 E0.0388
G1 X173.405 Y165.689 E0.0149

Its the last line of code in the start script (G1 Z4 ;lower z axis 4mm) that it ignores. So from G91 to G28 it does it alright but it dont execute the last G1 Z4.
I want it, after G28 to lower the bed (or raise the nozzle) 4 mm and then descend to the first layer height (0.2 mm in this case) while moving to the start point of the print.
It worked in Cura with the exact same start script but it dont with S3D, and I really want to use S3D...

Before I can grasp what you say and its quite possible that I have setting that contradict one an other, but I dont know which it is.. my setting in config M558 looks like this

; Z probe
M558 P1 H3 F200 T2000               ; Modulated IR probe, also used for homing the Z axis
G31 X-22 Y0 Z0.77 P500              ; Set the probe height and threshold (put your own values here)

And it the last command in my start script that dont work, lowering the bed 4mm and then go to the start of the print and while doing so lowering to the right print height..

Hi I am having a hard time understand what I am doing wrong. I want my printer (a corexy, Duet 0.8.5, FW 1.26.1) after homed all axis and before start printing to lower the bed x mm so not scratching the bed moving to the start point of the print but it is ignoring the last line. I understand that this was change with a firmware upgrade demanding a S2, but I cant get it right... Should I have this command in the start script (S3D) or in the homeall.g file or in homez.g? And how should it be written to work?
My homeall.g

G91                       ; relative mode
G1 Z3 F200
G1 S1 X-400 Y-400 F3000   ; course home X or Y
G1 S1 X-400               ; course home X
G1 S1 Y-400               ; course home Y
G1 X4 Y4 F600             ; move away from the endstops
G1 S1 X-10                ; fine home X
G1 S1 Y-10                ; fine home Y

; If you are using a microswitch for Z homing, insert similar code for the Z axis here,
; but use lower feed rates suitable for your Z axis.

G90                       ; back to absolute mode

; The following code assumes you are using a Z probe to do Z homing. Remove it if you are using a microswitch.
; Adjust the XY coordinates in the following to place the Z probe over a suitable spot,
; preferably near the centre of the bed if your Z probe supports that

G1 X180 Y190 F5000
G30
G1 Z4
G1 X0 Y0 F5000
G1 Z4 S2

My homez.g

G91
G1 Z5 F2000
G90
G1 X180 Y190
G30
G1 Z4 F2000

My start script

G91       ; set coordinate system to relative mode
G1 Z3     ; lower z axis 3 mm
G90       ; set coordinate system to absolute mode
G28       ; home all axes
G1 Z4     ;lower z axis 4mm

Any help or hint will be much appreciated!

@Danal Maybe I have to ask you about your config file? I cant get my head around this (in spite of David´s good description, or maybe I am to tired) so maybe I have to rebuild the end stops to looking like yours... Is it possible for you to share your homing files also? Just as info...

undefined

Ohh, thanks David, you are a savior! I was feeling a bit helpless (very much that is!) not understand what to do...
I will try this and report back... Have a good weekend!

undefined

@Danal Thank you but that is what I have been doing and it moves correctly but it mirrors the prints, that is where I started...
It dont seams that anyone could tell what I can do about it, hardware or software wise, to correct it (the mirroring!).
I know I could mirror it in the slicer software but thats just a half way solution since I am trying to sell this printer and I want it to work correctly...

undefined

@Danal No, when looking at my printer from the front I have the origin in the left top corner (like where you start reading a book, kind off!) the Y axis are pointing toward me and the x axis going to the right

undefined

@dc42 Hi David So according to that page my axis moves correctly now but since I have a left-hand axis setup (yes I know I am sorry but its a lot of work making it a right-hand) and there is no solution stated if one has one " If instead it is 90 degrees clockwise, you have a left-hand axis system, which will give you mirror-image prints" what can I do to correct it? Besides rebuilding the machine that is?
And thanks Ian for your input, I feel like I have 4 toodlers in my head now...

undefined

@dc42 and @droftarts Now I am even more confused since dc42 is saying no swapped cables and you are saying swapped cables!?

undefined

@dc42 Hi and thanks for your input but according to this diagram https://duet3d.dozuki.com/Wiki/Test_axes_or_motors_individually the command G1 H2 Y10 F1000 should move it in -X +Y and my printer moves in +X -Y and the command G1 H2 Y-10 F1000 should move it in +X -Y and my printer moves in -X +Y .
Thats why I dont understand this! And I did reboot the firmware after every change in config and issued M564 H0 before any other command... So what am I doing wrong or dont understand?

undefined

@mrehorstdmd Thanks for your reply but its not the origin that is the problem, I cant get the axis to move as they should and I cant figure out why!
@droftarts Thank you for clarifying the reversing thing! And now I have gone through every possible setting with both swapped and non swapped X Y cables and nothing of them works!!!

With swapped X & Y cables & command :
             G1 H2 X10 F1000          G1 H2 X-10 F1000      G1 H2 Y10 F1000        G1 H2 Y-10 F1000
                                   
M569 P0 S1                           
M569 P1 S0   it moves in +X -Y        it moves in -X +Y     it moves in -X -Y      it moves in +X +Y

M569 P0 S0
M569 P1 S0   it moves in -X +Y        it moves in +X -Y     it moves in -X -Y      it moves in +X +Y  

M569 P0 S0
M569 P1 S1   it moves in -X +Y        it moves in +X -Y     it moves in +X +Y      it moves in -X -Y 

M569 P0 S1
M569 P1 S1   it moves in +X -Y        it moves in -X +Y     it moves in +X +Y      it moves in -X -Y


No swapped cables & command :
             G1 H2 X10 F1000          G1 H2 X-10 F1000      G1 H2 Y10 F1000        G1 H2 Y-10 F1000
                                   
M569 P0 S1                           
M569 P1 S0   it moves in +X +Y        it moves in -X -Y     it moves in -X +Y      it moves in +X -Y

M569 P0 S0
M569 P1 S0   it moves in -X -Y        it moves in +X +Y     it moves in -X +Y      it moves in +X -Y  

M569 P0 S0
M569 P1 S1   it moves in -X -Y        it moves in +X +Y     it moves in +X -Y      it moves in -X +Y 

M569 P0 S1
M569 P1 S1   it moves in +X +Y        it moves in -X -Y     it moves in +X -Y      it moves in -X +Y

The only setting that comes close to any solution is with swapped cables and with either:
M569 P0 S1
M569 P1 S0
or
M569 P0 S1
M569 P1 S1
but they both fail to move the Y axis motor correctly
So, please can anybody make some sense out of my diagram??
Is there anything in my config that in some way flips the Y axis or is there some other place it the firmware that could cause this behavior?

undefined

Just (a probably stupid) question.
Should sending M669 from DWC reflect the changes made to the M569? Because it dont for me...
And an other (stupid?) query.
If I changed the order of the 4 cables on the motor (so it changes direction) is it the same as changing the M569 value?
I am really tired now so bare with me Have been sitting with this problem for 3 days now...

@droftarts Hi and thanks for reply!!
No that page I had still to discover (didnt think there where any left for that..;-))
But tried the first command to no luck

With command:
G1 H2 X10 F100

M569 P0 S1
M569 P1 S0   it moves in X+ & Y+

M569 P0 S0
M569 P1 S0   it moves in X- & Y-

M569 P0 S0
M569 P1 S1   it moves in X- & Y-

M569 P0 S1
M569 P1 S1   it moves in X+ & Y+

I have tried every way to changed my corexy printer to a right hand axis but no luck and its driving me insane, any help would be greatly appreciated!
My start problem is that my prints are mirrored!
I have tried to swap x & y motor cables, I have tried every combination with the M569 command (both with swapped and no swapped cables) I have tried the M567 command with both Y-1 & Y1 (and it gives me that its not a valid command anymore) I have tried the M669 to flip the direction of the Y motor, I have read so many threads here and the configuration guide that my eyes bleed. And nothing seams to help... And I dont know what I am doing wrong so please, any input would be great!

Hi David!
And thank you so much! Its not so clear what one should choose, but maybe there isnt many left off us using the older boards...
Grateful for fast reply!

undefined

I am sorry for being stupid also (and for hijacking this thread) but I cant understand which off the many version off .bin files @ https://github.com/dc42/RepRapFirmware/releases/tag/2.05.1 I should use to update my old 0.8.5 duet card! I currently use 1.19 firmware.
So please anyone, enlighten me?

@KeeganB
Its a bit strange since I did assigned an M587 S"Hus9" P"xxxx" and it did return the 0.0.0.0 adress but when putting on the main power it did return a valid IP and I can connect from DWC.
Now I have another strange behavior: I have set the current to x y and z motor currents to 800mA and the x and y axis sounds great but the dual stepper z axis dont sounds happy (vibrating a lot) tried a higher value (1000mA and 1200mA) and it sounds even worse, I then tried lower it (to 500mA) and now they are silent. Thought that since there are 2 steppers that they would sound better with a higher current but not…

I did all this with just the USB connected but when turning on the main power and sending M552 S1 I finally got a valid IP adress, Yayy!! Happy times!
