Just got my MP3DP up and running and it appears that the printer is not starting at zero for the Z-axis. I leveled my bed to end stops 0,0,0 no problem. When I run a print, printer will auto home and then move to print, but it appears the Z axis is not getting back to Zero. I’m assuming this is a set-up field somewhere, but unsure if it is in my gcode program (Cura 2.1) or settings in Marlin. Any thoughts?
