@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.

@droftarts Leadscrews. If you're interested, we've attached a video in the post above.

@dc42 @T3P3Tony Thank you! It's nice that the problem was fixed so quickly!

@T3P3Tony @dc42 Glad to hear this!
I'm relatively new to your platform, but it's nice how customizable it is and how responsive the developers are.

@dc42 Good afternoon!
We join the question from Cognirit about issue solution in beta3. We also are very much looking forward to a soon release in which this problem will be fixed. Thanks!

@droftarts We have a positive experience with sensorless homing and leadscrew on Z axis. We would not like to use endstops in terms of amount of wiring. Are there any workaround solutions to this problem?

Hello. We are developing a 3D printer that has 4 motors that are used for AWD Core-XY kinematics (like in VzBoT 3D-printer) and another 3 motors that move the table along the Z axis. The 3 Z-axis motors are connected to a Duet 3 Expansion 3HC. We would like to use sensorless homing for all motors. However, in the article “Duet 3 with CAN expansion firmware configuration limitations”, it states that “Stalls of expansion board motors cannot be used for homing. We expect to remove this restriction in firmware 3.6.” For this reason, we would like to know when approximately firmware 3.6 is scheduled for release. Thanks!
