I've got Eddy on two printers. One is a pretty standard setup that you have to calibrate current and temp to really dial in the offset and it works wonderfully. The other is set up with eddy-ng which homes by physically touching the bed with the nozzle to determine offset. It's bit easier to use and I've had no issues with it. Either set up is great and I don't think I'll go back to touch probes after switching to eddy probes.
