Describe your issue:

I have been having issues getting getting my Stealth changer build working correctly. I am able to see almost everything that is connected. The only exception that I have is my tap sensors. I know that the sensors work with my current setup as the switch on the current tool worked before I installed klipper tool changer Now I am unable to zero my Z axis.

I have scoured my Configs and haven’t found anything that I can see wrong. I have attached the configs that I think are relevant to my problem just in case you need information that is not in the log file, that is a fresh log starting the printer and trying to home. I have also connected a second head to try and prevent the error of all or none of the sensors being triggered.

The current error messages I get when trying to home my machine are “Failed to detect active tool”, “Internal error on command:“INITIALIZE_TOOLCHANGER”“ , “and Internal error on command:“G28”“ These errors have persisted even if changed the polarity of either of my current connected switches of if I switch which tool is being used.

Any help would be greatly appreciated.

Hi @MetalDragon ,

I would ask this on the StealthChanger (Draftshift Design) discord.
