Solved Dual X endstop homing
-
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 ---> StopIn 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 S1For 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 X0:3M119 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

I presume you are using RepRapFirmware 2, because homing using dual endstops is different (easier) in RepRapFirmware 3.
In order to move the U axis when homing, you need to temporarily make the U axis visible. So change your homex.g file to this:
M584 X0 U3 P4
G1 S1 X-605 U-605 F360
G91
G1 S2 X5 U5
G90
G1 S1 X-605 U-605 F360
M584 X0:3 P3 -
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: 1.22.6Is Maestro compatible with RepRapFirmware 3 ? i've had trouble to find the latest firmware for my hardware.
Edit : foundI 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.

Please post your entire config.g

@Boulet_Frites said in Dual X endstop homing:
Is Maestro compatible with RepRapFirmware 3 ?
Yes it is, I am running RRF 3.01 (RC11) on a Maestro.
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.
Check your Steps/mm for the E0 motor, it needs to be the same as your X motor of course.
I am doing the same thing, in RRF3, also on a Maestro, but with a double Y instead. I do not have that working completely either

@DeltaCon said in Dual X endstop homing:
Check your Steps/mm for the E0 motor, it needs to be the same as your X motor of course.
No need, as long as the M92 command comes after the M584 command then it will set the steps/mm for both X motors.
-
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.

As you are now using 3.01-RC11, you don't need to create the U axis. So:
- Remove everything to do with U in config.g
- Change your M574 X command to: M574 X1 S1 P"xstop+e0stop"
- Change homex.g and homeall.g to home the X axis just as if you had only one motor
In M119 and in the Endstops list in DWC, X will show as stopped if either X endstop switch is triggered.

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

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