ABS printing sample

I've got a part here, I'd noted that shrinkage issues persist near the build plate (at 115 DegC) so, heck lets flip it around and allow distortion where it does not matter so much on the part!

Here are some results of that, generally good but the shrinkage is pronounced. Any pointers or insights?

It is printed in an enclosed chamber at 235 DegC head temp and the chamber is about 35-38 DegC.

I will post my print temperatures for ABS.

Nozzle Temp ( at 232 DegC )
build plate (at 96 DegC)
Enclosed chamber 35-38 DegC

I 3D Printed every part for the MPCNC carriage with every part fitting perfectly together.

45-50C chamber usually works well for me.

it might be caused by chamber fan cooling models down too quickly; shift or close the fan for a try.
or you may change filament from another manufacturer for a try.

115c is WAY TOO HOT for the bed
