More cooling is likely to:

increase diameter
reduce diameter variation

If you're still at only 1.73mm, I'd say keep increasing temperatures. For some reason, your setup is reading a little higher than actual. Go to 200 or 205C and see if you can get any additional speed, but even 12"/min is now within specifications.

Running significantly faster at 201c, getting 1.75 +/- .02

Thanks for you help!

My fan is not situated well and I would say is 75% blocked by the insulated hot end.  I can try moving it forward so there is more airflow.  Do you think this may help it?

1.75mm is still wider than I'd expect at 184C. Again, please try 195C and report back both speed in inches/minute, and diameter.

OK, I'll do that now

Speed is still the same.

Hope I didn't build it wrong

That tells me you're extruding too cool. It is possible your temperature sensing is a bit off. Try 195C and see what that does for speed and filament diameter.

I'll play around more with the temperature and see.  Only thing i notice is that the motor whines up and down as if sometimes its struggling and sometimes its not.  I'm not sure if this is normal.  I'm also not running with the fan, as this seems to keep the width consistently above 1.85.

I have pics of my setup on the gallery thread.   Any other suggestions?

Also, +/-0.07mm with ABS and a winder is not great! Something is definitely wrong, people hit +/-0.01mm with ABS and a winder.

I did remove the nozzle, cleaned everything up, installed the filter, and retightened everything back up.

Aside from I guess really slow speed, everything is working ok.

I dont know how you guys are getting 1kg in 8hrs. Just ran it for the first time this weekend and it took 25hrs to get 1kg of mg94.

Getting about 1.75 +/-. 07 at 186c.

Setup is vertical with a filawinder

Did you run it with the pound of material Tim sends first to flush out anything in the barrel after putting it together? If not, and that kilo was your first kilo, then I am going to guess that there are metal particles inside the barrel at the nozzle entrance that are blocking the nozzle. You'll want to heat the barrel and then remove power and carefully remove the brass nozzle and let it cool, then scrape, cut, or otherwise remove the plastic that will be stuck to the inside of the nozzle and you will see a ton of metal shavings embedded. Then, throw away that first batch of material because it probably has a ton of metal shavings inside it! After that, you will probably have no issues with blockages!

If that isn't the issue, then let us know!
