Just to be clear, the XYZ parameters in the G10 commands are the offsets of the tip of the nozzle relative to the head reference point. You can choose the head reference point to be wherever you like, but the G10 offsets, G31 offsets for the Z probe and M208 limits must all be specified in terms of the head reference point.

It's probably safest to choose the head reference point Z position to be the lowest nozzle you have (or slightly lower), so that the Z values in G10 commands for other tools are all positive.

Thank you all for the help. Now I can start a print with no tool is pre-selected and finish the print with all tools parked. The problem solved by un-checking the Wait For Temperature box! So now a print starts with both tools heat in standby mode.
And to make the tools reach the temperature before they start printing I put M116 in tpre0.g and tpre1.g (because I removed the M109 by un-checking the Wait For Temperature box in S3D).

@phaedrux Thank you! interesting info!

Whdn you move the motors by hand they behave as generators. That is why the blue LED came on. If you move the motors by hand quickly then you might damage the drivers. So when moving them by hand, do it slowly. If you will be moving them a lot while you make modifications to your printer, disconnect the motors from the Duet.

Thank you! I got it homing now. I'm loving this board, the firmware and the support!

@wilriker Well I'm learning then 😄 Hopefully I'll be able to not get surprised 😄
