@ringo1508 You connect the convertor to the power supply. The positive to the output side, and the negative drrectly to the bed. The ssr will control the positive going to the bed. Connect the ssr input to the bed connector on the duet. Pay attention to the polarity on the ssr. If the ssr is one of the crappy ones, you won't get the full 12vdc to the bed and run hot.

M204 commands in the GCode are likely to disable dynamic acceleration adjustment if you are using it (see https://duet3d.dozuki.com/Wiki/Gcode?revisionid=HEAD#Section_M593_Configure_Dynamic_Acceleration_Adjustment) but are otherwise not a problem.

Yes, I think that looks correct.

you can measure the phase resistance that will give you some indication.
0.9 degree motors in my experience will lead to an improved 3d print.

@veti said in Heatbed questions:

yes 6.2A is no problem for the duet.

+1. I run about twice that current with no SSR and works just fine.

@ringo1508 said in Another power wiring question:

The bed is 24V. The SSR is only to turn the 24V PSU on/off so I can leave the board on all the time via the 5V PSU that powers it through the external 5V connector on the board.

Oh duh. You did say that in your first post. I just forgot. 🙂

@dc42 so awesome! Thank you! I understand now. My Duet 2 Wifi should be on it's way sometime soon. Cannot wait!

@ringo1508 said in Thinking about using Duet for new build, but have questions:

I also want to experiment with printing taller (in the case of RC planes, being able to print a larger portion with less work after the fact.)

Delta printers are good for printing tall parts. But are you sure that you want tall parts, not longer parts? Think carefully about which way you want the layers to run, to get maximum strength in the directions where you need it.
