What has everyone done to solve this issue? I saw some aftermarket heating modules that people would sandwich between the perboard and plate. Or do people just transform the printer into a pla only printer?

The aftermarket heater module for the bed is a good solution and gives you everything you want. You can fudge you way around the issue by sealing the top vent/opening and preheating the chamber with an air heat/hair dryer. This will give you the "heated chamber" the Mini design promised but failed to deliver. This sealing and heating will help the cooler parts of the platform keep warmer and they will reduce the shrinking that is warping and pulling the print off the perfboard.

Going PLA is the other alternative but since the Up printers use a direct drive with a stepper that gets quite warm, printing PLA tends to be problematic. The simple way to get it working - use a high softening point PLA (like Colorfab PLA which has some PHA to help the melt point) or you need a cooling mod like the one proposed by Drew. Though applying this to Mini mine be a little more complex.

With all of these options you will still most likely want an extruder temp mod.

I thought I saw the top vent sealing piece in thingiverse, but I can't find it anymore. Do you have a link Roller?

Interestingly enough... the words on my temperature controller chip has been filed away. Using a thermometer I did measure that the bed is hovering around 60 degrees though.

I'm still sourcing for the 100 degree chip, I guess I should try the vent sealing if I can find the part.

Most have been using an 80C module I think and reported a great deal of success.

I just filled the gap with foam - no fancy printed parts.

I have a Plus as well as a mini. I use an 80C thermostat chip on the mini and only use Up filament. As long as my mini prints are under 100MM, I never have any problems with the thing. I think I have gotten a total of two jams in the mini and that's it. I don't understand all the negativity about the printer as it has been great for me.

Not hating the Mini, but just wondering why if going slightly above 60C means it would have worked better you kinda have to wonder why they didn't put a higher one in the first place?

I've gotten one jam, so far, and other that the warping which is stopping me from printing stuff > 80MM wide I'm fine with it. Can't wait to mod my temperature chip and get it to work better.

Roller, we're talking about the gap where the filament goes in from the top right? just seal it up so it's a smaller hole to let less heat escape right?

I think I'm going to convert my mini into a pla printer.

I plan on disconnecting the ribbon connector to the heat bed and attaching my octave pla module. What setting should I put it to?

Ok, I'm new to this, so I have to ask, why don't you just use the PLA nozzle temperature setting?

Yes, by the gap I meant that great big port at the top where the filament tube gets into the case and where all the heat leaks out.

With doing PLA:
1) don't disconnect the heated bed - 50C is about perfect for good PLA like Colorfabb
2) Due to the direct drive design of the Up extruder (PLus and Mini) most PLA filaments will fail. You need one with a high softening point like Colorfabb OR you need a cooling mod (Drew has posted about his air cooling mod a couple of times - run it with a cheap fish tank air pump).
3) You often still need a temp mod as PLA is more temp sensitive than ABS and to get optimum prints and removal support you want to be able to dial it in.

Ok, I'm kinda glad that I decided to just go with ABS for my intial 'experience' then! :P

I just bought another mini for 300 with shipping because he thought it was broken and didn't turn on. He never thought of pressing the power button to turn it on

I got even a better deal. I Paid $175 shipped for a "for parts or repair" UP! Plus 2 that the seller said didn't work properly, he said that it would randomly lose tracking on x and y.

But I have had it for about two weeks now and it is working flawlessly.

Oh nice! People who sell 'broken' UP printers usually don't know how to use them...
