On PLA, I'm loving it.  I've yet to have a warping problem.  Compare that to this ABS model I made (top is original rubber bucket)

That just might be the worst warping I have ever seen. Ever.

Do yourself a favor and switch to Lawsys MK4. You can use the stock 'doodle tensioner arm or the one in the file. It makes cleaning out your hotend a snap.

That is a thing of beauty after last night's puzzle!

I hate to answer my own post, but rule one is don't forget to change the default temperature to 180 when using PLA.

This little red bugger of plastic got enough heat to bend into a blob at the entrance to the nozzle. I had to take the thing apart to fix it:

I wait until the bed is near my printing temprature. I then start slicing my model in RH using Slic3r. When the slice begins, there is a check box labeled "Begin printing after slicing is complete" I check that box. The software will then heat up the hot end after the slicing is finished. It will begin printing once the hot end reaches the desired temprature. I programmed mine to kill the hot end temp and bed temp after the model is finished printing. Therefore, my hot end is only hot during the print which reduces the amount of time the ABS is being heated unnecessasarily.

If my software skills were half as good as my mechanical and design skills, i'd be dangerous. We never get everything in life, do we?

Seriously, my trick is to manually run out some filament after it gets up to temp and when I'm still putting finishing touches on a model in CAD, or slicing, or respraying my aquanet, etc. I never go more than 5 minutes without extruding manually, turning it off, or running a print. Once I get my quick change extruder printed and working well, I'll be a bit more daring. But with my current extruder design, it's a complete pain in the neck to remove the hot end, so I baby it. 

Thanks for your post Mark. BTW, how do you like working with PLA?

This is not the point of this post so if you are looking for a solution, I'd recommend search and reply on other threads.

The point of this post is to ask, what are the best practices to keep from getting a clogged nozzle?

Anti-patterns are fine too.... like "I did this and ended up with a clogged nozzle".  I'll edit and add to the wiki if this post gets some good replies smile
