Hi,

Thank you for your very interesting ideas; i'll try it ASAP.

I'm always astonished how much things this board can do !

Hi all,
Extremely satisfied with my last project involving a duet 2 (my custom machine is working flawlessly for 2 two years), i've moved into a more sophisticated project.

The goal of the project is to give medical student a "radiology simulator" ; moving a fake radiology device that will display them a picture corresponding to the position of the device they'll chose.

I need to move 7 axes with physical buttons (no problem with M581 command i guess)

but then i need to press another button that will triggers the following events :

• get the machine coordinates ( for example X5 Y-5 Z10 U12.5 etc.) --> M408 command ?
• open an URL containing those coordinates (send an http request containing those coordinates to a raspberry or computer connected by RJ45 or USB)

I've access to a Duet 3 Mainboard 6HC, Raspberry pi 4 and / or windows 10 computer if needed.

Thanks for your help

Edit 2 : Adding "H1" in the homex.g made everything works very well ! Problem solved Thank you very much.

I did whay you said, here is my :

Nothing has changed. Moving is still good but for homing nothing happens.

Edit : If i ask with the console "G28 X" it says me that Error : G0/G1 : insufficient axes homed

In order to simplify the resolution of the problem (and maybe help @DeltaCon ); i've upgraded to 3.01 RC11 too.

Behavior of the machine :

X move goes well with the two motors synchronised.
M119 reports good behavior of the endstops.

Homing is not working at all. If i ask for homing X,Y or Z the color of the button on the touchscreen goes from blue to red. Nothing moves.

Thank you for your help !

Sorry i didn't mention it :

Firmware Name: RepRapFirmware for Duet 2 Maestro
Firmware Electronics: Duet Maestro 1.0
Firmware Version: 2.03 (2019-06-13b2)
Web Interface Version: 1.22.6

Is Maestro compatible with RepRapFirmware 3 ? i've had trouble to find the latest firmware for my hardware.
Edit : found

I followed you advice and now the U axis is moving for homing but the motor is turning very slowly; not at the same rate than the X motor.

Hi,

I'm very happy to use Duet3D boards for custom machines and i didn't have trouble with the setup of a Duet2 wifi and stalldetection endstops.
My new project is using a Duet Maestro and for this i need to use mecanical endstops and a dual X carriage.

I've got one motor on X and the other one on E0, same for the endstops.

Endstops are connected with two wires :
NC --> Ground
C ---> Stop

In my config.g :

M584 X0:3 Y1 Z2 U3 P3
M569 P0 S0
M569 P1 S1
M569 P2 S1
M569 P3 S0
M574 X1 Y1 Z1 U1 S1

For my homex :

M584 X0 U3
G1 S1 X-605 U-605 F360
G91
G1 S2 X5 U5
G90
G1 S1 X-605 U-605 F360
M584 X0:3

M119 shows me that the endstop works well.
But only the X motor homes, the E0 motor is not moving.
Would you know what is the problem here?

Thank you very much

Etienne
