Rostock Max V2 with HE280: Elephant foot issue

[Dataro81]

Hi,
I have a Rostock Max V2, with a couple different mods:
1) Hotend Accelerometer Probe board
2) E3D V6 Hotend
3) Ball-Cup Delta Arm Kit
4) 3D printed ABS platform to support the E3D V6 with the Accelerometer Probe Board

For the most part, my prints are coming out fairly well. The issue im running into is a slight elephants foot on all my prints. I do the calibration with the preheat set to pla to ensure that everything is expanded and still get this issue. How do I resolve this?

Thanks,
Chao

You're printing too close to the glass.

Or maybe an Initial layer line width too high

That's not going to be caused by being too high on the first layer. It's "overs-squishing" the first layer.

Sorry geneb i think i bad translate what i was meaning (my english is not the best). I mean maybe the "initial layer line width" value is too high, wich could cause an over extrusion. I had a similar result when i was setting my printer.
