Printing issue, cant figure it out i3v 12"

Hey Guys,


I am having an issue with printing, it seems that on corners, the printer goes to far and then comes back, making overally round corner. It also appears to not do so hot on smaller holes. I have checked the belt tension on both axis's and they are the same tension and I have belt tensionors on them. I have gone through all the calibrating and calibration prints come out almost dead nuts. I have tried Slic3r, Cura, and MatterSlicer and they all do the same thing, so its not the slicer. I am printing at 30mm/s, using a .4 nozzle, .2 layer height, and .4 extrusion width. I have acceleartion set at 500 and jerk at 15. I use a E3D head with 1.75 filament and this happens with PLA and ABS printing at 210 and 240 respectivaly. I have a MakerFarm i3v 12" printer. I have attached photos.

My 10" does similar out exterior corners. I just adjusted my Y belt tension and also found a loose wheel on the extruder carrier. I plan on printing something today. I'll let you know if that does anything for me. I'm looking forward to hearing others ideas here.
