reason being my klic-n-print has modified extruders for flexible filaments, but I still have problems loading ninja and filaflex.
And the main reason is that it loads filaments too fast and the really flexible ones still get jammed.
If I could slow the loading speed of new filament I think it would solve the problem completely.

I can load the slightly stiffer flexibles with almost no issues, occasionally have to back up and have a second shot. But I have a fair amount of filaflex and ninjaflex and a good commercial use for it and it just won't load. I'm certain if I could slow the filament load speed it would solve the issue.

So is there any way to do this ?

I have just found a menu item labelled eeprom. Which said: 'this could brick your printer press up to continue.'
I have not pressed up yet :-)
