Pause until Z sensor removed/attached

PeteL · 16 Aug 2020, 16:04

I have a FLSun QQ-s Pro which has an auto level sensor that you only connect when you want to check for bed level, and have to remove for printing.

At the moment I use the code listed below in the bed.g macro to ensure I have added the sensor before starting.

M117 ; Ensure you have attached Z-Probe.
M577 X S2 ; wait for end-stop to trigger
M577 X S0 ; wait for end-stop release

Is there a way of moving end-stop trigger to E1 as I don't currently use this, and I have an end-stop type button I could use? If there is a better method to do this please feel free to explain it (as if to a total beginner ).

Regards,
Pete.

Hi,

Have you considered using M291?

With the right parameters it can display a message and wait for a mouse click.

That's perfect, just what I was trying to achieve, and without any additional hardware.

Thanks.
