Wanhao Duplicator I3 3D Printer

Oh, you mean you just changed the settings, not reflash the firmware itself.

[tahustvedt]

Yes, I open "Firmware EEPROM Configuration" and change the settings.

I'm having a lot of trouble with clogging now. The filament is clogging the PTFE tube above the hot end in conditions which have been working fine up until now. I have printed 1300 m of filament now. The tube is deformed and brown on one half, but I ran a 2mm drill through it and it works for a while. This time I flipped it around. Will it print like new again if I replace the tube completely? It's frustrating. Maybe I should make an all metal hot end.

[tahustvedt]

I decided to try making one. Stainless and aluminum, like the Swiss hotend. Only the nozzle left to make now.

[tahustvedt]

It works. It's so much easier to manually push filament through this hot end. It's been printing for a few minutes now, and even holds the temperature with the DiiiCooler on full blast. I'm stoked. I hope it lasts.

I had lots of trouble with the metal hot end once I installed a powerful fan. Turns out I need a much shorter retract setting, probably due to an effective heat break. I can actually print without the extruder fan running and it doesn't overheat. It's great now. Haven't tried higher than 120 mm/s, but it copes with that just fine.

I designed a new fan duct yesterday which mounts everything behind the X-axis, and is very effective. Check it out:http://www.thingiverse.com/thing:1090433

Well.. I would not buy any Wanhao printer.
They don't accept return by their policy even though the printer is defective:

Just to cite it in the policy "RETURNS/REFUNDS: Although we offer a 3 year warranty, there are no refunds or returns on any items purchased through www.wanhaousa.com unless it is due to a shipping/delivery related issue."
They say warranty, but they don't respond after they sell.
Don't buy a Wanhao. You will 100% regret.

Oh man - I am a noob to 3d printers and researching what is within my budget. I was seriously looking at this one. Good thing I held off on getting this!

The Wanhao i3 works fine right out of the box, but with some tinkering it becomes a fantastic printer, so for the money it's a good deal. I'm printing at 90 mm/s with a metal hot end, and have printed for ten hours a day on average since september fifth.
