If you are talking continuous extrusion speed I am not sure. But when I purge or load / unload I run it at 900mm/m.

1) The Bowden tube is too small for the filament (cheap filament often goes over 3mm)
2) Nut on Bowden tube has compressed the opening of the tube.
3) Dirt in the nozzle hole.
4) J-head has been over tightened and the Teflon liner is compressed and restricting the filament.
5) J-head has gotten to hot near the top and is melting the filament prematurely which increases the force required to extrude (this is usually because it has been on for hours and hours without the fans being on).
6) Temperature is too low.
7) Too much tension on the idler springs.
8) Bad filament.
9) Gear on the extruder motor is slipping.

If it measure 3.0mm +/- 0.1mm you have cheap filament.

Did you get the kit with the 4 heavy springs or the 8 lighter ones? I have the 8 on two machines and the 4 heavier on the other machines and they work the same.
Here are the results from my calibration. I then just interpolated to find the intermediate values and replaced the temp for the actual temp in marlin.Quote

I would be interested in knowing how far off the temp table in Marlin is to the actual temperature.
Pointerace Setting Actual Temp 160 164 170 171 180 191 190 193 200 203 210 211 220 221 230 231 240 241
