“Print a Nema 17 motor found of Thingaverse, run the fake stepper motor to reduce weight.”
Sorry, I didn’t get that…
Where do I use this fake stepper motor? Reduce the weight of what?
Ok, duel extruder printers have two stepper motors, the style is " nema 17" one for each extruder. If you only print with one head, remove the motor from the Un used side. Go to thingaverse and search for nema 17. Print up a nema 17 motor and place it where the old one came out. This can reduce the weight up to 40% and will reduce ghosting.
Start with as many as you can. Save the suggestions to notepad or word. Then. Check them off as you go down the list. Once you get your profile and machine tuned, changes become less frequent.
By the way, at some point FlashForge started shipping a polycarbonate bed with their printers (I think it is blue, I don’t have one). If you’re using one of those, you really don’t want to use acetone on it. Acetone won’t dissolve polycarbonate, but it does attack it and weaken it. It also is able to etch polycarbonate which will change the surface texture perhaps to be more sticky.

If you’re going to switch it to 1 extruder my recommendation would be to print up this instead.
Indeed S3D have this setting for “dense layer(s)” on to of the supports, defaults to 0, but can be changed to f.e. 3 (if 1, then bridging between the non-dense and the only one dense layer may make it very uneven). Then another setting let you decide of the distance (in layers) between that dense layer and the part itself. I think I use 1 most of the time.
What I wanted to add to the dense top support setting advice is that you could get better results if you would raise the part see for like 3mm so the whole ‘bottom’ would be printed on the dense layer and then get more uniform results (but of course loose the shiny mirror like flat bottom you would have got from slury/spray on glass :-))
Tested that, and still have it on without the upper fan and without the lower fan duct (that duct is not very optimal compared to some circular ducts you can find on thingiverse). My point here is as much as I value that thing, it aint perfect yet.
If I was to do it again, I would go for the printed hollow nema.
And for the fan, well, I suspended 45° over my FF a fan like this and it does an amazing job (at the lowest speed of course)
Yes, I know, that’s unusual 
I had the same problem using the stock blue build-tak that it comes with, it sticks worse with time. I removed the tape and started using a glass plate with ABS juice. It still sticks like the devil sometimes when I put too much juice on the plate, BUT I can easily remove the plate and put the whole thing in the freezer for a few minutes, afterwhich it pops right off. A side benefit of the glass plate is that you can look at the bottom of the print and see where it’s already coming off the bed, which give you a clue as to where to start prying.
