in your homex.g do you see the commands to lift the z up and down?

G91 ; relative positioning
G1 Z5 F6000 S2 ; lift Z relative to current position
G1 S1 X-305 F3000 ; move quickly to X axis endstop and stop there (first pass)
G1 X5 F6000 ; go back a few mm
G1 S1 X-305 F300 ; move slowly to X axis endstop once more (second pass)
G1 Z-5 F6000 S2 ; lower Z again
G90 ; absolute positioningalso unless there is a specific reason, you should go with x16 and interpolation.
do you have 0.9 or 1.8 degree steppers? -
@Veti I know, that means it rises 5mm before x home .... but it rises more.
1.8 degrees.
In the configurator I set x256. I will do the test with x16 but I don't think that's the reason -

.... but it rises more.
measure the exact distance with a ruler. more does not give any clues as to what the difference is using the manual movements from the web interface.
-
you were right. it was enough to set x16 and the right steps to fix the z shift.
strange, I didn't understand because with x256 it moved too much.
thanks for the advicenow another problem has arrived. The extruder does not work.
I warmed up, I enabled the tool, but the extruder does not send the filament forward or backward.
The engine works well because I tried to connect it to x driver.
so I think that the E0 driver is broken.
I tried to use E1 modifying the config like this:
M569 P4 S0
M584 X0 Y1 Z2 E4
But it did not work.
Is it possible also the E1 driver is broken?When I had the duet on another printer I found the extruder motor cable fused. Could the E0 and E1 drivers be broken?
How can I check?
-
to rule out config problem reconfigure it e0 as x and connect the x stepper to it.
see if you can home.
Be aware the M584 has to be one of the first commands in the config. -

Be aware the M584 has to be one of the first commands in the config.I did the test you told me.
E0 and E1 drivers work great with X and Y motors.
I put the connections as first ..... extruder does not move.
I also tried cold extrusions but it doesn't work.what can I do?

Hi,
Did you verify that the cables to the extruder motors are good?

The motor and cable works well because I tried to connect it to x driver.

I read that you tried the X,Y motors with the E0,E1 drivers. I missed where you tried the extruder motor with the X driver.
When trying to extrude via DWC do you have a tool selected?

it was written in the previous post
sure, otherwise the extrusion and protrusion button is disabled
-
can you tell us step by step how you are trying to extrude? every button you press, every command you issue.

first method:
power on duet
home all
activated heater
heated 200 °
in "extruder control" pressed extrude
then retract.second method:
power on duet
activated heater
in "gcode console" given command M302 P1
then G1 E50
then G1 E-50nothing moves
-
can you verify with a multimeter that the phases on the extruder stepper are correct.
i.e. one phase for red and blue and one for green and black. -

@fcwilt
activated the heater means the same as selected the tool.@Veti
yes is the first thing I checked to run it correctly.
I found that my hardware is perfect because I loaded the Creality Ender 3 Pro predefined configuration from the RepRapFirmware Configuration Tool and the extruder works.so there's something in myFW that doesn't make the extruder go.
I have the BLTouch, connected to the heater 3 (disabled as in the tutorials).
does it interfere in any way?in the meantime, thanks for the support

I cannot check right now but I'm pretty sure a tool can have it's heater in the standby state without the tool being active.

do you have a config-overwrite? because you have a M501 in your config.
please post the config where it was working.

I'm not sure if it's useful. I had enabled it along with the ability to save the print in the event of a blackout.
please post the config where it was working.
checking it I saw that:
; Tools
M563 P0 D0 H1 F0in my CR10 file config D0 is not there.
I don't know why the online configurator doesn't create it.
can it be the cause? I haven't had time to try yet.
