Eddy Duo Z Home with Sensorless XY

[loud cedar]

Hi everyone, Im finally about to finish my first Voron. A 350mm 2.4. Im at the Klipper configuration stage and honestly just stumped and not sure how to proceed.

I currently am doing sensorless XY homing and that works properly, I have a BTT Eddy Duo for probe and Z homing, but I am unsure how to get the Z hopming to work with the sensorless XY homing as well. I followed the BTT guides for Eddy Z homing, but they have a [safe_z_home] setting which doesn't work with the sensorless homing_override . Because of this I am stumped how to proceed.

Does anyone else use this same homing config, or similar? Am I wasting my time with it?

• Manta M8P v2.0
• PI CM4
• Kinematic Bed Kit
• Lightweight X Gantry
• BTT Eddy Duo on Stealthburner
• BTT EBB36 CAN board

The thing to realize, is that safe_z_home is very simple

It makes sure z homing happens where you want it to (the middle of the bed). And it makes sure there's a little bit of a z hop before x/y homing.

That's it.

So as long as you make sure your chosen [homing_override] tends to those same matters?

You should be fine

Would I be able to just copy and paste the part from safe_z_home into the macro for homing z? Or would I need to convert it to gcode directly?

[twilit halo]

You must deal with it in gcode

But...most of the sensorless homing macros around already deal with that stuff

So look and see what you've got before you go too far off the rails 😛

I definitely see a move to center in there

That's the most important part, by far. I don't see a z hop

So a Z Hop should just be a positive move along the X Axis?

[twilit halo]

no

the idea is to move the toolhead away from the bed

so if it happens to be against the bed (or a failed print, or whatever), it lifts before it starts homing X/Y

My bad, I meant along the Z access. So just like 5-10mm up before starting the homing process?
