Hi,
Can anyone help me...please.
I have recently purchased my Ultimaker and although i have been fiddling, changing, swapping, tweaking and learning for what seems like weeks now and still don't have something you could really call a print..... i love it. I purchased the machine for the challenge and to learn new things - it hasn't let me down - i just wish i could print something. :cry:
My question is to do with the extruder. I have read many threads detailing the importance of getting the right amount of tension and have experienced what happens when you tighten the screw too much or too little. What i don't understand is why my extruder is spinning so much and so fast. This results in the filament being sent, smoothly to the hot end to start with and then lots of slippage and strange noises from the extruder motor there after. I have looked at as many working Ultimaker videos as i can find on YouTube and all seem to have a much slower spinning feeder wheel. Which makes sense to me..... why is mine going so fast?
The motor is very hot in comparison to the other two motors.
I have tried to print a few different files the one shown below is the 20mm box from .....

I have had the same extruder spinning wheel problem each time. I have also tried to print directly from an SD card on my controller.
1,
This first video shows how quickly and how much the wheel is spinning. This is at the start of the print.
2,
This one shows it stopping quickly as it is going. This just before the filament stopped coming out of the hot end.
3,
This one shows the wheel stalling and making a whining noise. I am fiddling with the wheel which shows there is no resistance.
Sorry about the toilet in the background!!!

20mm box
I am printing using Cura (mainly because this is the only program i can print from for various reasons). I am on a windows 7 machine.
These are screen shots from Cura to show settings.
These are my 'prints' so far....
Thanks to anyone who can help
