XYZ carriage rise without reason

MrOppip

duet 2 wifi with fw and DWC updated to the latest version (not beta).

hello, I connected the duet to the cr-10s pro.

when I ask x home the carriage rises
about 10 cm, then goes back down and continues the home procedure.

I also ask z home (with the bltouch) and the carriage stops
about 10 cm away from the plate; on the DWC it says that it is 12.5 mm but it is not true.

could it be a step problem on the z axis?
I have the original leadscrews and I don't know how to set the steps.
double axis z.

any ideas to solve the problem?
I can give you more info if requested.

thanks

@MrOppip Your homing files determine what happens during homing. Post your homing files.

MrOppip

I put the .json because you could see all the configuration from the browser.

here are the individual files:
tpre0.g tpost0.g tfree0.g stop.g sleep.g retractprobe.g resume.g pause.g homez.g homey.g homex.g homeall.g deployprobe.g config.json config.g bed.g

Veti

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

; homex.g
; called to home the X axis

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 positioning

also unless there is a specific reason, you should go with x16 and interpolation.
do you have 0.9 or 1.8 degree steppers?

MrOppip

@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.

MrOppip

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 advice

now 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?

Veti

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.

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

Veti

can you tell us step by step how you are trying to extrude? every button you press, every command you issue.

MrOppip

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-50

nothing moves

Veti

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

@MrOppip

I don't see where you selected the tool.

Frederick

MrOppip

@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

Hmm...

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.

its shouldnt, but its an easy check. comment the line and try it.

do you have a config-overwrite? because you have a M501 in your config.

please post the config where it was working.

MrOppip

@Veti said in XYZ carriage rise without reason:

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.

config Ender.g

checking it I saw that:
; Tools
M563 P0 D0 H1 F0

in 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.

Veti

yes
If there is no 'D' field the tool has no drives.

ok! sorry for the delay but I checked only now.
the problem was just that "D" missing.
now everything works as it should.

Thanks for your help.
