Hi,
I 'm searching for some more info of the Up Mini and I was wondering if you can use PLA filament with the same extruder or do you have to change something.
Best regards
Use PLA filament
Re: Use PLA filament
You can use the same extruder but because the Mini doesn't have manual platform leveling (making it less practical to print raftless - which in turn makes PLA printing less hassle) and the enclosure tends to retain the heat which is less desirable for PLA print quality as well as causing the Extruder to heat up causing jams with soft PLA then I would say it is not the best choice for PLA. The Up Plus is a better choice though you will probably still need to add some cooling mods to reliably print with any PLA.
If you are happy to use premium PLA like Softfabb which has a higher softening and melt point then either printer will do fine.

Re: Use PLA filament
Hi roach,
When you switch from ABS to PLA let it extrude @ ABS setting and then put the setting to PLA/gram in the software.
Most of the ABS left behind in the extruder will get purged out this way.

Always breath out on the way UP
Re: Use PLA filament
My biggest problem with PLA (and the problem I probably won't switch over permanently, even though the Colorfabb stuff is awesome) is that raft and support removal are a pain in the ass (at least compared to ABS). But warping with ABS on certain parts _might_ be a bigger pain in the ass. 

Re: Use PLA filament
The support removal is about finding the right temp setting and still far superior to support removal on reprap. Of course on reprap you can TURN SUPPORT OFF.
Raft support is clean and trouble free once you get the rght temp with Colorfabb ... which is about 200C on ABS setting. The only reason I use Colorfabb is so far I haven't managed to jam it. All my other PLAs that I use on my reprap have jammed once the extruder warmed up. I'm going to add chilled air injection to fix that soon.
