I'm in a VERY well air conditioned Lab and will have the fan in place so the filament should be cooled quick enough to help stabilize the diameter.  That in conjunction with the winder should help immensely.

I guess I should have clarified myself.  You are absolutely correct but I was referring to all of the other nuances that this finicky material has.  I do appreciate the heads-up though.  By the way my S&R guys finally brought up my delivery of the Filastruder and Filawinder today.  I don't know why but I thought they were going to be bigger than that.  Don't get me wrong I very happy about that.  They will take up much less room in my Lab.  Before you go there I know the dims are on your web site I just never really looked at them. smile  I can't wait to assemble the system.

Assuming that perhaps a 30 or 45deg set up might be better for PLA, but then perhaps a vertical setup can be achieved with sufficient cooling?

Dave, with a vertical setup you won't need a filament guide.

For some reason beyond my comprehension I have yet to have successful extrusions of pla with a vertical setup...

I've only done ABS so far. But I've read posts that there's a challenge with PLA vertically because the material remains soft so the weight pulls the filament too thin.

Ah, wasn't aware of the pulling bit, Hmmm
Yeah I was going to set it up vertically, should be interesting.

It seems that with PLA the distances between the nozzle and the first time the extrusion touches the guide are pretty crucial to getting straight filament and for preventing build-up at the nozzle itself later in the extrusion.

It is important for all polymers, not just PLA.  The first 6-12 inches should be pulled straight by hand, then laid over the filament guide. Positioning for the guide was described in the assembly manual.

You could also try a 30deg, 45deg or vertical setup.

I'm looking for experience outside of just Tim's here, so if anyone else out there has had good success with PLA please do post your measurements or ideas. Basically just looking for as wide an experience base as possible.

Thinking I'll just print my own guide as my previous hacked together thing began to cause trouble.
