G30 / G28 Bad Command
I tried to get my BL touch sensor running and unfortunately I come across problems.
The sensor itself works and does what it should. It is even possible to determine the offset value.
But unfortunately he always says G30 or G28 Bad Command.
Duet Board 1.04c
BL Touch Sensor V3.1
This is my pinning:

Actually, I kept the instructions one to one. Unfortunately, I can not continue at this point, because I'm quite new to the topic.
Sorry for the whole text, but I hope you can help me.
Thank you very much
there seems to be a problem with the deploy and retract script.
can you execute the command manually in the console and check for extra characters in the script.
Yes, all work fine. Pin Down, Pin Up, Selfe Test ON and OFF.
also the Z Probe value (1000) is displayed in the test
what is the size in bytes of the deploy and retract script
here the whole content of the files
; deployprobe.g ; called to deploy a physical Z probe ; ; generated by RepRapFirmware Configuration Tool v2.0.4 on Thu Sep 26 2019 16:26:18 GMT+0200 (Mitteleuropäische Sommerzeit) M280 P3 S10 I1
; retractprobe.g ; called to retract a physical Z probe ; ; generated by RepRapFirmware Configuration Tool v2.0.4 on Thu Sep 26 2019 16:26:18 GMT+0200 (Mitteleuropäische Sommerzeit) M280 P3 S90 I1
can you issue the commands M401 and M402?
there is something wrong with your deploy and retract scripts.
delete everything and type the commands per hand

Delete the probe files and create new ones with just the M280 command,
Perhaps there is something in the existing file that is causing the problem.
Error: Bad command: M280 P3 S10 I1
Their is only the M280 command in the file.
Okay. now it works fine.
I deleted all again and created again. Thank you very much!!
