Been too busy to post, but here's what I've done with mine:
- I built a small workbench out of 2x4s with 2x12s as the top (used a leg kit from 2x4basics.com). Super stable and much better than the cheap Ikea desk I had it on. Need a rubber mat for the top now to further reduce vibrations.
- Someone in this thread suggested to rotate the power plug / switch panel so that the switch is easier to access. I cannot recommend this simple 5 minute mod enough! The power plug was always in the way of the switch and it's no longer an issue.
- Disconnected the stepper motor driver fan. Amazing that such a little fan is so loud! I need to run my printer a bit and check driver temperatures with and without the fan to see if it even makes a difference. Prior to this, I had made a little duct so that the fan would blow more air onto the drivers.
- Upgraded my z-axis rods, build plate, and hot ends with jfkansas' offerings. HUGE difference. Build platform is much more stable now and print quality has improved.
- Built an air scrubber based off a design I saw on Thingiverse. Mine uses 100mm Sundstrom respirator filters that are available on Amazon and eBay. Hopefully it will cut down on the smell when printing in ABS. The cool thing about these filters is that you can stack them. Right now I'm running a P100 particulate filter plus a VOC / chemical filter. Will put my design up online soon!
Next up, I'd like to work on soundproofing a bit. Unfortunately I have to keep my printer in my office and the noise gets rather annoying. I was thinking of applying Dynamat or a similar sound deadening material to all exposed metal surfaces. Maybe even build an enclosure around it.
And finally, I have an annoying problem: the little blower has gotten pretty loud. Sounds like the bearings are shot. Any leads on a high quality replacement?

My neverending battle with ABS continues. I typically have zero issues with PLA, but ABS causes me so many headaches.
Most prints, as long as I manage to get adhesion to the bed, I'm good.
However, I've now got a problem with ABS where I get a good centimeter of printing completed, and then the piece will come free of the glass like so:
Any tips on getting past this issue? It's a continual problem for me with ABS.

When I do ABS (and PLA, it works well for both) I've used an ABS slurry. Very thin, mostly acetone, and I roll it on with a metal rod or a wooden shishkebab stick. Let it dry while the glass is cool, and it should be alright. I use white ABS leftovers and keep it in a jar. Looks like thin milk.
I got a new glass plate yesterday to replace one that broke. I put it on and tried printing PLA to it. It just stuck. I added nothing to the plate. It was pretty entertaining. I've since added a thin slurry coating to it, though, after some larger prints popped off early.
That being said, you might check:
1. Your level. I find if anything's out of whack, that sometimes helps. If you're not level in the spots that need to be, it can mean your initial layer isn't going down clean and then there's less to hold it.
2. Add a skirt. 1 layer, 10 lines. It'll help to hold it down, at least for the first couple layers.
3. Try turning your bed temp down. Sounds weird, but I was printing ABS at 90C and it was working just fine.
4. Make sure the cooling fan isn't coming on at some odd time. You can turn it on or off manually on the printer's settings, or within the software if you're using one that allows it. You shouldn't need the cooling fan on at all for ABS.
5. Check Lefty or Righty, depending on which extruder you're using. I had a hell of a time printing with Righty, with Lefty basically knocking the entire print/glass off the bed once the print got to a certain height. This can also come from uneven leveling of the bed. If it's getting knocked off at the same spot each time, this or something similar might be the culprit.
6. Slow it down. If you can set your layer speeds, set the first couple of layers to 50%. You could also try turning down your overall print speed and see if it helps.
I hope it helps. This is all stuff I've had issues with in the last month or so, and I'm hardly an expert.
