New printer, will not print, fails after a few layers

[Oldmopars]

I just bought a new CR-10. I got it home and went through set up and watched videos, etc. on getting it set up. The bed has been trammed several times, however I think there may be some warpage, so I set to tramming just the center where the print was and this helped that issue.
The big issue I am having seems to be related to the extruder/hot end. I followed the process for setting the E-Steps. However the standard number is 97 and I had to run it all the way up to 244 to get it to feed 100mm of filament. I also had to crank the hot end temp up to 250C just to get it to feed that.
Even after doing that, I attempted to print the Dog file that came with the printer and it still fails. It gets to the infill after the first couple layers and it seems to be going way to fast to lay down the filament. It just balls up.
I have been at this 3 days now and I still can't get it to print the stock dog file.
Any suggestions?

Well, I think I may have found the issue. No where in the directions, or anywhere else I looked when setting up my printer made any mention of the Bowden tube needing to be pushed all the way into the cooling block down to the nozzle. Having no idea this was necessary, I just shoved it in a little way, leaving a huge gap at the hot end.
I watched no less than 5 You tube videos on "Beginner" set-up of the CR-10 and this subject never came up. About 8 videos later, researching my issue I found a great video of how the hot end works, and found out the importance of this and it completely explains all of my issues.
I guess, as the saying goes, you don't know what you don't know.
BTW, my full time job is setting up, repairing and training on the use of industrial CNC waterjet cutting systems. It was starting to drive me nuts that I can fix $300,000+ systems, but can't get a $300 CNC printer to print one part.

LOL yea, that is kind of how these systems work. Your original description sounded line an insufficient heat problem.

So, on a related note, how do you slow down the infill speed? it seems a bit too fast and does not lay down like I think it should.

Velocities are managed by the recipes in your slicer. I don't know their software.
