Hey guys,  
im back with another issue. Ive recently installed a Eddy USB Probe to my printer and wanted to use the Eddy for bed meshing and my already installed BL-Touch for homing and Z-Tilt adjust.

I installed everything like described, but after Including the Eddy.cfg i created, which includes the g-code for the eddy, it gives me the error “gcode command QUERY\_PROBE already registered” after i save and restart. When i take a look into my printer.cfg and my Eddy.cfg, there is nowhere a QUERY\_PROBE macro to be found… what am i doing wrong and how do i get these two probes working together?

Thanks already in advance!

`QUERY_PROBE` is established by Klipper by including a probe. So you get this issue.

[https://www.klipper3d.org/Config\_Reference.html?h=probe#bed-probing-hardware](https://www.klipper3d.org/Config_Reference.html?h=probe#bed-probing-hardware)

Also - AFAIK - only one probe is allowed. You have to decide what to use.
