Thank you for your kind and informative response. I did not realize attaching both cables was not an option and redundant. It does work with the 4-way cable alone but not with the ribbon cable alone (white screen) so the 4-way cable is the solution.
Yes, <LF> for line ending provides for a better output indeed. The baud rates were matched. This Duet/Ethernet board is new as was delivered from Filastruder on 12/26/19. The PanelDue was from GB (Roland Lock).
M111 S0 turns of the repeating data ;)....lol
Next the config.g and how to get my x, y and z axes to zero out as need to print brackets and such in order to mount my new BL touch and filament sensor all using an Ender 3 Pro as a basic start.
The Duet 2 Ethernet board runs the stepper motors very smooth as compared to the stock Ender 3 board.
Do you recommend a better way to perform homing (new technology) /style of sensor?
I am a retired instrumentation engineer (university research) but new to 3d printing and new to G-code but will build my own 3d printer from scratch at some point.
I love the quality of your products thus far.
