thanks to photobucket for the help.

4th attempt ruined.....
cleaned the extruder... printed the same model again. this time half the project printed fine, then no more filament and pufff. dead
any ideas guys ?
thanks.

I don't consider 70 slow
I've not had this problem, but a lot of people do when using the stock drive mechanism. It is very intolerant to changes in the diameter of the filament. You could try backing off the tension screw on the drive a whisker, but then you might get slippage if the filament has a thin spot. If you are watching a print and notice the grinding you could try to adjust it on the fly and add a little manual extrusion help to get it past the point of grinding.
Long term your best bet is to produce an alternate drive. There are a number on thingiverse, and posted here. Bertho and chopmeister both have one. Their designs are much more tolerant of filament change due to a bearing and spring mechanism.
thanks for the tips.
i will have a goodlook at the other options for the extruder setup tonight.
I would be very curious to see what other members here have used and there feedback on what works and doesnt ?
best wishes.

For me it has been a case of just not over tightening the adjustment bolt on the stock
feeder. I've perhaps been lucky with the quality of the filament I got when I bought the UM, and have not bought any more since.
I do intend to build one of the others at some point though
