DISABLE_INACTIVE_E In Configuration_adv.h is incompatible with IDEX

change #define DISABLE_INACTIVE_E true to false

Okay ellensp ... that works fine :)
can you help my by my last problem too ?

i have one stepper port free ... but when i disable exp mot vsc says no e plug left for z3 but i have one free ... do you now where i can cahnge it ? or i can set z3 for ... e?..... ?

thank you dude

[ellensp]

octopus, It can have 8 stepper drivers
It comes configured as X, Y, Z, Z2, E0, E1, E2, E3

Do you mean BTT_MOTOR_EXPANSION? With gives you E4, E5, E6 ?
Unused extruders can be reallocate for other axies.

Without knowing what your #define EXTRUDERS is set to and what you have plugged into where... I cant really say.

[r4ph488]

I think i dont need exp mot... Should i Upload my configuration.h and ADV ?

thank you :)

There is an issue with the code.
Since the octopus already has a Z2 pins defined, the reuse allocated E as Zx code is getting confused.
Its still allocating a E to be for Z2 when it shouldnt..
Working on a fix

[ellensp]

Can you test this PR, It should work.

[r4ph488]

does the bugfix now fix the problem?
//edit
now it works great work :) fine thank you

but now e1 dont work anymore :-/ hotend heats up but the motor dont step....
ican heat up e0 and e1 ... e0 steps ... e1 not #define DISABLE_INACTIVE_E false should be ok

[ellensp]

A new fix for the "No E stepper plug left for Z3!" issue has been added to bugfix. Give the current bugfix a try.

[r4ph488]

Yes now all Stepper in the octopus i dont need the Extension Board more...
But now e1 has Power but dont step.

[ellensp]

enable #define PINS_DEBUGGING in Configuration_adv.h
re Compile and upload
Send the Machine a M43 and capture the output.
Zip up the output and attach in a reply
Looking for any weirdness in E1 pins...

[r4ph488]

debugging.txt

Ok i have attached ...

[ellensp]

himm getting weird repeated values in that output.
LESEN: PIN: PC13 M42 P45 E1_STEP_PIN protected
LESEN: PIN: PF0 M42 P80 E1_DIR_PIN protected
LESEN: PIN: PF1 M42 P81 E1_ENABLE_PIN protected
but it shows the correct pins according to pins diagram https://github.com/bigtreetech/BIGTREETECH-OCTOPUS-V1.0/blob/master/Hardware/BIGTREETECH%20Octopus%20-%20PIN.pdf

[r4ph488]

OK and what can i do ?

[r4ph488]

Ok i have tested ....
i have activated btt extension board
i have changed e1 ( motor 5 ) from my octopus board to e4 from btt extensionboard ... now e1 works ....
but not on the octopus board.... only motor port 5 dont works correct....
any idea where the problem is ?
