extruder works but print not starting

[Marine85]

@phaedrux many thanks
I will do these modifications and check

[Marine85]

I think the problem is with remapping the Extruder to driver "6" (E3) on duex2
but when reconfigure it again to driver"3" it works but the independent Z homing macro not working!
the macro was working fine when i map drivers 2,3,4 and 5 to Z with virtual axis U,V and W.
any help please how to sort our this issue?

Thanks,

1. Is your config.g file the same as in your post of 15 August?

2. Did you make sure that Tool 0 is selected, either in your slicer start GCode or before you start a print?

[Marine85]

@dc42 Yes it is the same config

I am wondering whether the stepper driver 6 output could be faulty. Can you try driver 7 instead, if it is a DueX5 not a DueX2? Alternatively, test driver 6 by e.g. connecting the X motor to it and using X6 in the M584 command instead of X0.

[Marine85]

Unfortunately i have duex2 the driver is working when assigned to stepmotor not extruder.
May be if i ordered duex5 would be a solution or this may be bug with the firmware?

[dc42]

No i don't think it's a firmware bug. Please try removing E6 from your M584 command and changing X0 to X6 in it, and with the Duet powered down move the X motor connector to the E3 connector on the DueX2. Then power up and test the X axis. That will show whether the E3 driver (driver 6) is working correctly.

[Marine85]

Hi Dave , I remapped the driver 6 to x and it is working now.
i will check the printing today.
I have another question I am testing PNP sensor LJ12A3-4-Z/BY and i did the static testing and it give me 1000 in in DWC.
when i configure my homez.g using this code Homing Z using a Z probe the z moves 4mm and stop
G91 ; relative mode
G1 Z4 F200 S2; raise head 4mm to ensure it is above the Z probe trigger height
G90 ; back to absolute mode
G1 X100 Y100 S2 F2000 ; put head over the centre of the bed, or wherever you want to probe
G30 ; lower head, stop when probe triggered and set Z to trigger height

I used the code of Homing Z using a Z min endstop switch in homez.g
and looks working i dont know if bed probing will work or not herein my code

config.g

; Axis Limits
M208 X0 Y0 Z0 S1 ; Set axis minima
M208 X1200 Y1200 Z1200 S0 ; Set axis maxima

; Endstops

homez.g
G91 ; relative mode
G1 Z4 F200 S2 ; raise head 4mm to ensure it is above the switch trigger height
G90 ; back to absolute mode
G1 X0 Y0 S2 F2000 ; put the head wherever you want it to be when you home Z (omit this line if it doesn't matter)
G91 ; relative mode

@marine85 said in extruder works but print not starting:

Is the reading 1000 when the sensor is close to the bed and triggered, or when it is far from the bed and not triggered?

[Marine85]

Reading 1000 when triggered and sensor indicator led on

[dc42]

You need to use different commands in homez.g to home Z using a Z probe. See https://duet3d.dozuki.com/Wiki/ConfiguringRepRapFirmwareCartesianPrinter#Section_Homing_Z.

[Marine85]

when i use this homez.g
G91 ; relative mode
G1 Z4 F200 S2; raise head 4mm to ensure it is above the Z probe trigger height
G90 ; back to absolute mode
G1 X100 Y100 S2 F2000 ; put head over the centre of the bed, or wherever you want to probe
G30 ; lower head, stop when probe triggered and set Z to trigger height

x and Y axis only moves to 100,100 and Z not moving up or down and reading Z 4.0 and when i home z again z value increase by 4 becoming 8,12,etc..
the sensor reading is 0 when not triggered and 1000 when triggered .

I tried to print but when heating is ready and homing x and Y showing this message and aborting the print
Error: G0/G1: insufficient axes homed
Cancelled printing file panal.gcode, print time was 0h 1m


help please with this issue ?

[dc42]

Please try sending these commands from the console and see whether you get the correct 4mm of Z movement.

G91
G1 Z4 F200 S2

[Marine85]

yes when i send
G91
G1 Z4 F200 S2

z moves up 4 mm
but z not homming when i try to home only moves up and x , y 100

[Phaedrux]

Do you have a deployprobe.g and retractprobe.g files in your system folder?

[Marine85]

@phaedrux i am not sure i will check tomorrow

[Phaedrux]

I also just noticed that your G31 command lacks an X and Y coordinate.

[dc42]

but z not homming when i try to home only moves up and x , y 100

So Z does move up by 4mm? In your earlier post you said:

x and Y axis only moves to 100,100 and Z not moving up or down and reading Z 4.0 ...

[Marine85]

@phaedrux Thank you this solve the issue with Z homing now homing
