I presume much of this is due to resilience of the belts and motors where there is a small amount of hysteresis. The head doesn't quite reach the intended position.
Some articles make this a hardware cause and offer no solution; where the obvious solution would be for Slic3r to overshoot the infill turnaround point slighly so as to encroach onto the perimeter in a controlled way.
Does Slic3r ha

Oh sorry, but you did say feed rate which implies filament feed rate not print speed. Also, that is so slow that I was assuming you meant extrusion speed.
In that case, you have something very seriously wrong. A partial blockage is the usual culprit. Do you get the same with all 3 inputs? I've only ever had this happen once, just after I assembled a new one. The fix for me was t

12mm/sec extrusion rate is pretty dammed good. If you are trying to push filament through that fast, no wonder the force is high.
Assuming 1.75mm diameter filament the area is about 2.4 mm^2 so at 12mm / sec that's around 28.9 mm^3 per sec. The best you could hope for on something like an E3D V6 is about 15 mm^3/sec and on a volcano it's about 40 mm^3/sec. So your getting almost

I found filament temp was critical with the Diamond. A light breeze from the part cooler and the extruders started skipping.
I then insulated the cone with cotton wool pads and Kapton tape, but it is difficult to make it stay in place. I glued the cotton wool to the hotend with silicone, but the pad fell apart after some weeks.
A silicone hood might be the best option.
I appreciate

Whilst the Diamond Hotend has lots of promise, the force required by the extruders is extreme such the fastest feed rate is around the 12mm/s.
What feed rate should I get?
How critical is the quality of PLA? Should I use ABS?
There are no jams as such, such the viscosity of the melted filament seems so high to limit feed so I either get slip or the filament buckles between the bowden and the t
