Thanks for the response.
The commands in bed.g were all valid.

What I didn't notice was that Simplify3d had the same commands in the start script, without the I parameter from back when I used the board that came with my printer.

Hi!

I finally upgraded my TEVO Little Monster with the DuetWifi last night.
I'm really surprised how well everything is working so far.

I do however have 2 problems, that I can't seem to figure out.

Every once in a while, I see a popup/toast in the webinterface displaying the message "Error: Invalid servo index 0 in M280 command".
Googling this tells me it has something to do with the BLTouch sensor, but it really seems to work fine to me.

My second issue is the auto calibration. When running this, the printer doesn't seem to know the XY offset for the BLTouch, so along the edges near my Y tower, the probe is used outside the bed. The trigger height is set correctly in config.g with "G31 P500 X0 Y20 Z0.89", but I don't see any settings for offset.
Where can I change this?
