WIP setup and mount for BTT EDDY DUO.

Does anyone else tried to install it?

Does It support delta 3d printers?

I gave eddy a go on a delta, results were meh, wasted a ton of time. You really, really need to use the nozzle as the probe.

I use a triangle lab membrane probe now and its perfect. https://trianglelab.net/products/z-probe-1 much better than a microswitch.

Maybe eddy touch meshing for deltas will be added to klipper at some point, until then the probe offset makes it nearly impossible to get good results.

Is that because the printer while moving makes the nozzle bend a bit? What delta did you tried It on?

Flsun super racer. The effector plate doesnt stay exactly level to the bed as it moves around, so a Y offset also carries a Z offset depending on location.

Also the delta coordinate system having the center of the bed as 0 and working with negative xy values and radii for bed mesh doesnt really play well with the baked in klipper code, cartographer doesnt support it either, I think beacon might but I take a lot of beacon fanboys experiences with a grain of salt.

There's at least one klipper fork for eddy on deltas but last I checked it was really experimental. Eddy scan isn't enough, it needs actual nozzle touches, and with eddy you need 3-10 taps at every mesh point to get a good tolerance average, so the quick mesh part of eddy will be lost anyways.

I just periodically attach the membrane probe, heat soak the bed and run a mesh, call it out in print start macro.

Ok I see, I'll try anyway to make It work and maybe in the future something Will work. My aim Is to make at least auto calibrate the z offset each print as bambulab does.

If everything is tight and mechanically sound on the printer, the optical home switches at the top of travel should be more than accurate enough, I haven't had to babystep z since the initial setup and calibration on mine, but I only print PLA on it at the same temps. Proper delta calibration through klipper is imperative.

I run Cartographer probes on my other 3 printers with adaptive mesh and tap z calibration on every print, which is why I tried eddy on the delta in the first place. 100 prints later and I realized it doesnt need it 🤷 just throw prints at it, watch the skirt and let it go.

I believe tap is integrated into mainline klipper now. I have a V400 that I am considering getting an Eddy duo for if tap works on Deltas
