Thanks again!
To clarify, you have your 1KW supply outputting to both of your 3HC boards and you 6HC board in parallel to divide the current and you have your current limited by running M906?
This question will show my inexperience, however it needs to be asked. If you hook up a 1KW power supply to the 6HC only, will it instantly blow the onboard breaker or will I have to pull current through it with a load to cause it to blow.
@theolodian Thanks for the replay. I feel I am misunderstanding something because that is 1440W. The board has a 15A breaker and with a 24V input, that is 360W before the breaker should blow.
What is the maximum power the Duet 3 6HC can handle? 360W?
I want to run 6, 24V, 4.2A stepper motors at once and want to know if this is possible using one power supply connected to the board or if I have to use expansion boards with dedicated power supplies.
