3HC sensorless homing
-
Hello,
It is possible to use sensorless homing on 3HC board? I'm currently using 6HC + 1LC and I want to add some more axes. 3HC is the ideal solution for me.
Thanks

ping for visibility....

3HC arrived yesterday so I can test it. Unfortunately, I was unable to commission sensorless homing. If I connect the U axis directly to the 6HC board it works without problems. As soon as I switch it to 3HC, I can't get sensorless up and running. I am doing something wrong?

@petrkroupa sensorless homing is not yet supported on CAN-connected expansion boards. I expect to implement this in RRF 3.5. Please see the list of limitations on the wiki. https://docs.duet3d.com/User_manual/RepRapFirmware/CAN_limitations

@dc42 - Thanks for the clarification. I was hoping that this feature will be in 3.4. It is true that 3.4 brings a lot of other new things. Good work!

Looking forward to the 3.5 release as I have just run into this issue. I had a quick look in the 3.5-dev branch commit history on Github and couldn't see anything as yet. Happy to help test any RC's once they're available. Thanks!

Good afternoon, can you tell me if you managed to solve this problem? Did you end up using the limit switches on additional axes or did you change the board / firmware / find another way?
