Pin virtual_endstop used multiple times in config

Basic Information:

Printer Model: Cartesian
MCU / Printerboard: Fysetc Spider V2.2
klippy.log Don’t have one yet

Describe your issue:

I am trying to configure Klipper to run my Cartesian 3D printer. I am having trouble with the diag pin for sensorless homing and the Fysetc TMC2209 v3.0 driver. Klipper keeps giving me this error " pin virtual_endstop used multiple times in config". I have been through the configuration multiple times and cannot see the conflict. The X and Y pins on the Spider V2.2 board share pins PB13 and PB14 with the X and Y min endstop connections. I want to use sensorless homing. When I add the diag pin configuration to my printer.cfg file, it comes back with the error. How do I configure the Spider V2.2 board with the Fysetc TMC 2209 V3.0 drivers to use sensorless homing in Klipper?

It’s very much preferred that you attach a log rather than copy pasting a wall of config text.

You’ve used the virtual X endstop pin for both the X and Y stepper.

Or at least put such code fragments between Preformatted text tags:

image734×324 6.84 KB

STRG+F in the config file and then search for the suspect.

As @jakep_82 already explained you used the same pin for X and Y stepper: tmc2209_stepper_x:virtual_endstop

I am truly sorry. I will keep this in mind for future problems.
I caught that after I posted this. I changed the pin numbers to the correct ones and it still has the same problem. I am using PB14 for X and PB13 for Y now but it still gives me the same error. I also removed the (!) and put a (^) in its place and the problem persists. I tried removing both the ! and ^ and the problem is still there. The only thing I can figure out is maybe Klipper is seeing the pins used for both the mechanical end stop and virtual end stop but I am not sure how to fix this. I am running Klipper on another printer with the Octopus Pro board and sensorless homing without issues. I am lost at this point. The Spider board doesn’t have the support BTT or Makerbase does and that is the reason I am reaching out to this community. My knowledge is limited to the basics when it comes to Klipper. Thank you for taking a look at my problem.

Great suggestion! Thanks.
I caught the use of the same pin for X and Y and made the change but the problem is stubborn. It was late and I was tired so when I get home today I plan to take another look at it. Thanks for taking the time to help.

Not sure, if you have caught the solution. You have a simple typo in your config:

[stepper_x]
...
endstop_pin: tmc2209_stepper_x:virtual_endstop
...

[stepper_y]
...
endstop_pin: tmc2209_stepper_x:virtual_endstop
...

You are using tmc2209_stepper_x for both axes

GREAT CATCH!! I found it just a little while ago. I was really tired when I put this together and fatigue got the best of me. Thank you so much for helping me with this problem!

Well, the honor is all at @jakep_82: Pin virtual_endstop used multiple times in config - #2 by jakep_82
I just repeated it, since I had the feeling it got lost.

Thanks to all of you!
I was running on three days of 4 hours sleep. I should have waited.
It is up and running!
