PLA - Temperatures

[uperator]

I feel like I should have been able to figure this out on my own
through searching - I ended up unsure and with questions....

What extruder temperatures are you running with MG PLA? Similarly,
what temperature are you running your heated bed?

I understand the range is somewhere between 190 and 230C (correct me
if I'm wrong) but I would like to get a more "practical machining"
figure to start. <-- unfortunately, the 28th edition of the
Machinery's Handbook just isn't up to speed with additive
manufacturing quite yet :D


My goal, this weekend, is to get the Up! printer dialed in for PLA at
temperatures more sane than 275C.

the results at 245C using MG natural white ABS

Stink factor goes way down, quality increases significantly. You still
can't print at .4 layer thickness due to die swell dissimilarities
(requires speed/feed change). .2mm thickness works well (just slower).



Also, it seems like this might be my first post on this group - if
so, my apologies if this post seems fairly solicitous with the linking
and whatnot.

Thanks!

Use of MakerGear filament in an Up printer is not supported nor recommended.

With all due respect - not supported by whom?

I understand it's not supported by the manufacturer as they want to
sell their own material... But is it also not supported by MG?
Obviously, you can't (and I don't expect) hardware/software support -
that would be nightmarish for you.

Which brings me here, to discuss further so I can make more informed
decisions... Unfortunately, my searches haven't been fruitful - not
nearly as much as when I searched for MG ABS temperatures. I've moved
forward carefully thus far and will continue to do so, that's why I'm
here :D I got my package of MakerGear PLA this past week and also a
package of spare parts from PP3DP for use with PLA - I'm ready to
go :)

"With all due respect - not supported by whom?" By MakerGear

I've had so many problems simply getting my Up! work reliably even with their filament.

Both of my Up! extruders leak ABS and the 2nd is new and has only been used their filament.

On an MG extruder, PLA is typically run in the 180 to 200C range. I have not tried PLA on the Up! but I'd probably start around 220C...if that works...then work down.

Thanks for the information - much appreciated :)

Sorry to hear your machine is giving you such a hard time with your
machine... I haven't had any problems other than a burnt out filament
feeder (which I killed myself, then repaired) - but I'm only a sample
size of 1. Have you got it working now?

Well, i cleaned the extruder and fixed the pre-feeder and on the first print the extruder is already skipping.

I have had to take apart and floss the gears many times. I am curious how you got a separate heat bed to work? Did you you unhook the cartridge heater and sensor? That assembly has died on me twice. They are good about replacements.

just so you know rick is one of the people running Makergear.

[Aaron Double]

There are more people than Rick?

I thought is was just him and his wife.

[uperator]

Yep :) (that's why I asked who it was that wasn't supporting the
material)

That is a dead link

what link?

I think he means this one
