@dc42 @T3P3Tony Hello! We installed firmware 3.6 beta3 and tested sensorless homing on the Duet3 3HC board. Individually all Z-axes perform homing without problems. However, when we tried to run homing with independent stopping (M574 Z2 S4) the system worked the same way as with S3 mode: when the first axis reached the end, all axes stopped. We tried running homing with the same settings, connecting the motors to the Duet3 6HC main board and it worked as it should: each motor stopped at the correct time. Is it possible that this is another unresolved problem with the Duet3HC Expansion board? I am attaching our configuration files. Thanks!

@dc42 Thank you very much! We successfully implemented unofficial 3.6.0-beta.3+4 build.The functionality we are interested in, including independent homing in S4 mode when connected to Duet3HC, works fine with it. We have not found for any other bugs, because we didn't do a full test. If we find any, we will write to you.
We are very satisfied with the use of sensorless homing for the Z axes, as it allows us to completely get rid of the end stops. We have been using this functionality for a long time in our previous 3D printers and have now implemented it in the new one. We would like to share our experience with those who may also be interested in this option, so that it is easier for them to configure and try it out. We attach a video of how the system works as well as our config files.
