Error: Invalid servo index 7 in M280 command
-
Hi,
Im having trouble using BL Touch after a fresh install.
I own a Tevo Little Monster delta printer, im following the configuration guide here :
https://betrue3d.dk/bltouch-on-duet-wifi-configuratio-and-usage/#usageWhen the machine starts up the probe goes trough the self test process correctly, but if i try to send any command trough M280 commands the error appears.
Any idea how to make it work??

Did you use M307 H7 A-1 C-1 D-1 to disable heater 7? Until you do that, you can't use logical pin 7 in M280 or M42 commands.

Alco check your config-override.g file if it exists for any additional M307 H7 heater commands that could be overriding your commands in config.g

Perfect, i did it and now the g30 command works.
I encounter another issue now, when i start auto delta calibration the bl touch isnt triggering because my machine wont move all the way to the plate when probing.
the only probing point it actually reaches the plate to trigger the bltouch is on the center of the plate, for the last probing movement. -
