Has anyone tried uncommenting the pressure advance settings in the standard config.g file? The values (0.2) look around right for a Bowden set-up, but when I turn PA on, the print speed is outrageously slow.....not sure why that is?
You need to increase your e-jerk in your config.g. Look for the line that says "Set maximum instantaneous speed changes (mm/min)" and change the E value to E800:800:800:800. Now things should run at a reasonable speed however if you try tuning it you may find you need much higher values than 0.2.
