Another learning experience for those out there configuring a duet 3, with beta firmware, when you do this M584 X0.0 Y0.1 Z0.2:0.3 E0.4:0.5 you end up controlling z motors when you try to retract/extrude lol BUT when you do:
M584 X0.0 Y0.1 Z0.2:0.3
M584 E0.4:0.5

Then retracting/extruding ends up using the right motors.

Now.... the last piece of the puzzle is the BLtouch and then setup mesh bed leveling. It does successfully self test a couple times when powered on, then led stays solid red and duet web interface shows "0" for z probe. When I try to do M401 then nothing.. if I'm using a duet 3 what governs "pin" or "servo" number in the below? (M950 S# or M280 P#) I'm running out of trouble shooting strategies..

config.g
; Z-Probe
M558 P9 C"io2.in" H5 R1 F50 T6000 A5 S0.02 B1 ; set Z probe type to bltouch and the dive height + speeds
M950 S0 C"io2.out"
G31 P500 X1 Y2 Z2.5 ; set Z probe trigger value, offset and trigger height
M557 X15:440 Y15:440 P20 ; define mesh grid

deployprobe.g
M950 S0 C"io2.out"
M280 P0 S10

uploaded my config here... first print went ok! but need to get some part cooling going on for PLA

@dc42 haha okay, standing by eagerly

@dc42 please don't take this the wrong way, but just for some planning purposes.. when do you think the next release will be out?

@dc42 Thank you!

@gtj0 would you please elaborate a little on how to "deploy" these changes? or x1,000,000 better.. do you have a bin for Duet 3 version v0.6 (MB6HC) that has the heighmap fix in it?

@brendon I'm glad it helped! Sorry, yes i should mark it as resolved. Still working on slicer settings, but hopefully will zone in on something functional!

@stereo for the low number of motors, probably no biggg deal for printing. BUT it makes a huge difference in the web/user interface speeds for only 40 dollarsish for a raspberry pi. Then you get the added benefits of taking pictures/streaming while you print, incase youre into that

new nuance found, to successfully save bed mesh grid (G29), you need to have a memory card hooked up to the duet 3 board. Running mesh bed compensation will not automatically understand to save to SBC if there is no mem card on duet 3, and I didn't find a way to point it in the right direction. After it runs, it will save a file to the board, cool but now you have to take the sd card out from the duet 3 and manually transfer that file from the duet 3 sd to your SBC sd card in the same directory as config.g (easier to just connect to your SBC through web and drag and drop the file.). On the plus side, it's time for my first test print! woohoo!

So new finding... Plugging in BLTouch to io2 had no success, BUT simply plugging into io8 works now?

Should I do a warranty claim @dc42? I had this same issue when with fans, some plugs on board seem to not function and changing to a different one caused the fans to work too
