BTT Eddy USB
Any chance there is an easy way to use an EDDY USB with RatOS?

No, it requires klipper source code changes
I tried and just couldn’t get it working properly. You have to strip too many macros and other items out to make it even remotely possible.
@Qui1zy I got it up and running on my VC3.1 400 a few weeks ago. I can share my cfg file when I get home in a few days. Not sure if I'm overall satisfied with the device though. I realized I didn't do the best job with the mechanical build, so I'm fixing a few things before passing final judgement
That would be great!
Are you trying to install, or making a purchase decision?
If you're already in the install phase and using the device as a probe, you will need to comment out all of the [probe] statements
I got one already for cheap, so I was just curious if it was worth it or not to add it to my printer. I haven’t installed it yet.
I've seen some inconsistencies with finding z0. This could be due to my z screws. I realized today the rear one was not completely tight to the frame. Gonna fix that over the weekend
Also, you have to install this exactly 2-3mm above the nozzle. Helpful to design a mount with some adjustability and print a 2.5mm spacer to sit the probe on when the nozzle is at 0
@Qui1zy i commented out the [gcode_macro G28] portion
Is that everything?
And then do I just plug it into the usb port? Or is there additional setup.
Comment out the [probe] statements as well. Plug the USB into the pi
@Qui1zy Here's some workaround to use BTT Eddy on the VC3.1, from my recent implementation.
My machine:VC3.1-500, BTT Eddy act as a probe and Z-endstop.
Perquisites: You need to update klipper tot the latest commit, no matter for a existing ratos or new install, the native support of BTT Eddy was implemented into klipper this October or November-ish. You can do this by ratos update manager.
Most of the steps below can be found instructions at BTT Eddy repo, to summarize:
1. Make and flash the firmware to Eddy.
2. Mount the Eddy to the EVA carriage.
3. Edit printer.cfg, comment out the [probe] and probe-related includes, as @EODesigns suggested. Then depends on the usage of Eddy, copy the configuration to user override section in printer.cfg from Eddy repo.
4. Comment the [gcode_macro G28］section of the Eddy macro.
4.Do LDC_CURRENT_CALIBRATE
5.Do probe_calibration
When mounting Eddy to EVA carriage, MAKE SURE that Eddy probe are 2-3mm above nozzle.
There is a discussion for my G28 and calibration problem, and solutions about these two, you can take a look, see if helps.
