Just started my first larger print with the DX - and first layer without much tweaking is already soooo much better than anything I could coax from the SX… If they iron out the teething issues, I guess this will be a very capable print head!
I’m now on firmware 1.15.21, and it still has the bug that after Z-calibration it starts ~0.3 mm too high into the print. In my current print left extruder needed -0.4 mm, right one -0.35 mm manual Z offset to get it right…
