I don't know how much it took, but you need to ask yourself a question. Would the extruder be able to work if it had to push with this much pressure?
If you think it takes too much force then two things could be wrong. The hotend is not getting hot enough or the hotend is partially plugged. If you do
not have a meter with a thermocouple you need to buy one so that you know that the hotend is getting as hot as the printer says it is. One such meter
is listed here:
http://www.amazon.com/AGPtek-Channel-Di ... uple+meter You start with a clean hotend that has no filament or bowden and bring it up to a set temperature then take the thermocouple lead
and put it down inside the hotend until it bottoms out inside the nozzle then you see what the thermocouple meter says the temperature is.
It's the only way to know that your temperatures are accurate. The other thing is the possibility of a plugged hotend in which case you will have to disassemble it.
Let me know!

Looks good for a first print. You may want to increase the number of bottom fill layers to help smooth them out.
You got it to print, that is the first part. How did you get the extruder to push the filament through?

If you have the funds you should still purchase the thermocouple meter. Everyone who owns a 3D printer should have one. It is the only way to verify that the temperatures
being reported are accurate. What kind of filament did you use to print what you showed and at what temperature?

Any recommendations for such?
Thanks!

Here is just one model, there are many others:

After Adding a lot of force by hand for about 40 CM of filament I just plugged everything back up as usual and ran it at 230 Degrees with an 80deg bed temp.
Seems like all it needed was a nice push!
The filament is an off brand from ebay to be honest I have no clue who was the seller and can't go back and look unfortunately they only show the past 90 days of items purchased.
Ok I will start counting my pennies for the thermal couple meter.
In the process now of printing a second test cylinder with no changes just to see if its like the one before. Then I am going to start making adjustments and checking the impact.
I may have built a new relationship with a company for filament and doing some tests for them. I will provide my reports soon.
Eaglezsoar any other basic tips for now? I still feel I need to go through polygon hells calibration for the extruder thoroughly. right now my steps per MM are 92.65. after doing my changes in Config H. it is MUCH MORE STABLE. I dont feel it crashes now and everything is the same. thanks for the tips!

No more basic tips. At this point it is the fine tuning that is needed such as the calibration of the extruder.
If after that calibration you are not satisfied with your prints then you need to do the complete calibration as listed in the assembly manual.
If you have any more questions, just pop another message onto this thread. Happy Printing!
