I went through the initial configuration tool last night and got it close then started transferring specific code from 2 to 3. And it looks like I have most of it.
One other question I have is that my x/y motors are open loop, one of the reasons for the upgrade, and now has a variable for the homing distance how does this var get populated? Is it directly from firm wear?
Unfortunately I'm not at computer right now but I will post code tonight.

Sorry if this has been addressed before. I currently run a duet2wifi and expansion board and have a duet3 hc6 to swap in but am unsure which files will need to be transferred from the 2 to the 3 to maintain proper functionality? Any assistance would be appreciated
