This post should be stuck to the top of the forum. 2 weeks in and mine developed the under-extrusion problem.

I suspect the unload/reload procedures - I wish it had some more 'manually' methods.

is there an official post with the things we should all be doing to get our printers working?  or is this going to be a time consuming effort going out and reading everything for details?

My printer has jammed a couple of times and it would not fully unload.  

I found these two steps worked:

  1. Reload the filament
  2. Unloaded a second time

awesome - but not what im looking for.

this is how to do stuff.  I want a checklist of things i SHOULD be checking and possibly fixing because of manufacturing defects or imperfections.

No manufacturer ever is going to do that with their product, it would mean admitting their product is faulty ("You are holding it wrong!"). More innocuous way is to add chapters in assembly and regular maintenance about common printing issues, then it's up to user to figure it out.

i respectfully disagree.  A smart business will respect its customers time so their customers can spend more money with them.

NOT doing this will make the experience worse for those that have had a terrible experience and drive them to look to alternatives.  This is business 101. Delight the customer.

I had a similar problem and it resolved with cleaning filament.

What filament? 

Slowing print down may help too, Slicer profiles are pretty aggressive with their speeds.

It seems to me like none of these problems were addressed because my August delivered printer has seemingly all of these problems.
