So before submitting this comment, I took a closer look at my slicer and realized I hadn't set it up properly. I had always used my laptop for slicing and printing, but this installation is on my desktop now that I can wirelessly send my G-code. Anyway, my nozzle was set to 0.5mm because that was the OEM hotend nozzle size and I had never changed it after installing a while back. That said, I still have a little underextrusion, but it's improved a lot.
@deckingman Oh you're right. I had only seen the bracket last I looked. But yeah that's it.
@Phaedrux
I suppose it's a little fast for the calibration part, but I've run pretty fast in the past without these issues. I'll reprint it right now with slower speeds and a fresh auto-calibration.
I'm running RepRap Firmware 2.02
I have printed something larger, although I didn't complete it (Had to leave and didn't want to leave my first run on the Duet while I was out of the house lol). The thing is that I used to get some really good results on this test piece with my Rambo. The Duet is clearly superior, but I'm missing something in my calibration or configuration.
The steps/mm was perfect on the Rambo and it's 1 step/mm above what is called for by Bondtech for this extruder.
And here's my config.g:
