I keep having issues with larger PLA prints on my MP mini, the edges like to curl up. I'm currently using green painters tape on the stock alumimum bed, but I'd like to find something better. I might try gluestick, or spend money on a buildtac or PEI build plate.

It's so tricky to get the bed trammed properly, there were a couple times I've put it a few millimeters out of wack lol.Not sticking on the edges could be an indication of the nozzle being just a bit too high on the first layer. It might be worthwhile to check the Z height adjustment.
Watch your hot end temp, and if it swings more than a few degrees you will need to tune your PID. I just got the same machine under a different brand and the PID tune was terrible, 10c plus/minus swings. Get your computer hooked up to it via USB and execute the Gcode through Cura, repetier, or whatever your choice. Guide found here http://reprap.org/wiki/PID_Tuning
After that, I would recommend you tune your E-steps to ensure it is pulling the proper amount of filament. Mine was off by 6% from the factory, leading to constant under-extrusion. The reprap website should have a writeup about how to do that as well.
Once PID tuning is done and e-steps are calibrated, everything else will be much more likely to yield quality and consistent output. This should be done on all new budget machines, and any time a new drive or hot end is installed.

:shock: Wow. I didn't catch that. I wonder why it was a suggested story for me since it's old.That was in 2015....
The Z height needs to be as precise as you can get it, but sometimes it's hard to get all 4 corners 100% perfect, and to compensate you can set your slicer to extrude extra material on your first layer. I find that this also helps with bed adhesion. The only minor drawback is that you end up with a slight lip at the very bottom of your print, but a quick scrape with a hobby knife or sandpaper takes it away.Not sticking on the edges could be an indication of the nozzle being just a bit too high on the first layer.

How does 3 point tramming work?I’m going to go to 3 point tramming when I get the aluminum plate and bearing upgrades.

While 3 point leveling is a lot easier to do, the downside is the lack of support on the corners allow the bed to wobble when the Y-axis is accelerating/decelerating. This can cause ghosting in the print's y axis.To flatten a plane it is easier to have 3 points, with 4 you are always off somewhere. I tried it with the stock plate as some did, I wasn’t happy, but the noisy bearings were a large part of switching back to stock.

I've always printed PLA with a bed temp of 60° (the max for my MPSM). I'll try to find some gluestick and print without tape, and I'll eventually get a PEI bed.

Do you guys keep logs of your print jobs? If so what do you record in them?
I use the log files in Octoprint and some Python scripts to extract the data out of them.Do you guys keep logs of your print jobs? If so what do you record in them?
There were some interesting announcements in 3D printing over the weekend, for those that missed it.

i just kept a sheet of paper with settings, and as I changed them I wrote them down. once I established my baseline, I copied the Cura config in windows.Do you guys keep logs of your print jobs? If so what do you record in them?
