I have my bed temp set at 100. For some reason my extruder head will only go up to 230C. That is better than 228C though… I am really going to consider creating a plexiglass enclosure for my Orion. I had a feeling that that was the case. I have been experimenting and printing bigger object and that is when I am seeing the adhesion issue. I have done all of the other steps. Thank you so much for your advice!

I had a similar problem, trying to break through the 230 barrier after I installed a E3d. The firmware limits the max extruder temp because the plastic part of the J head will melt at 240.

I agree, this is by far the best method for getting good layer adhesion. I actually have two build plates, one reserved for general use, one reserved for Kapton tape and ABS slurry. I took a nice (relatively) sealed glass bottle, cut some strips of filament and dropped them in side, then poured some acetone in. I keep it on a shelf and just slather it on if I need to print in ABS.

One thing to note is that it is better to apply the acetone slurry before you heat the bed. If you apply it while hot, it causes the slurry to bubble before the acetone evaporates, and the ABS left behind becomes pitted.
