@amagatth please do the tests as I suggested. For example you are calling homing files. maybe they are influencing this depending on what's in them
-
@t3p3tony ok i try that
-
@t3p3tony I tony the bl stop work when i send
G1 X30.1 Y200.0 Z0.19 F2500.0 E15
When the extrudeur work the bl stop to work
-
@amagatth ok so that is progress. Please post your config.g (using the </> tag to make it easy to view) along with images of how the BL touch is connected to the Duet and how it is mounted, showing the extruder as well.

@amagatth
and the bl is connected to the duet at io7 -
I edited the port to use </> formatting for posting the config.g so it can be read without downloading.
Because the BL touch deploys and retracts properly before you start the print I am assuming that the wiring into IO7 is correct.
From you configuration the input and output pins should not have a pullup resistor enabled:
M950 S0 C"io7.out" ; Creation Pin servo Bltouch M558 P9 C"io7.in" H10 F200 T25000 A1 S0.03 R1The BL touch should still work initially (test this please). It will hopefully now work after doing an extrusion as well. My guess is that the pullups + the extrusion noise put it into a weird state.
-
@t3p3tony I add the pull-up to try to solve the problem, I try Monday if it's better without that!
-
@amagatth
I had the same problem, but only when I changed the filament and extruded it.
I solved the problem by simply entering M84 E0 in start.g. Since then no more problems -
I try to delet pullup and bl work before print but not after extrusion
-
@amagatth the next thing to try then is to route the cable separately. The BL touch cable might be picking up noise from the stepper cable and that is causing it to get into an errored state.
-
@t3p3tony ok i try it
thx !
