I'm having big troubles dialling in the Titan (/w a prusa style blower fan).
Getting massive warping on the first few layers (first looks ok, the next few seem to shrink majorly). Also some inconsistent extrusion through the layers - guess I need to get onto that filament width sensor.
However that said I am fairly confident that this change is for the better, it will allow me to accelerate in x much faster due to lower weight, and extra accuracy will be good once dialled in.
I also found an issue with my y motor mounting being loose, so that should help with the ringing I have been seeing, and once again allow me to up the acceleration a bit.
