Interesting. That has not been my experience with ABS as I regularly print it on an open makerbot replicator duo (the original wood one)You need an enclosure to print with abs..
I was using it on a delta so not as big of an issue here, but I think it caused effector tilt because of the way the drive chain pushed on the effector. It also increases stepper noice because the stepper spins a lot faster because of the high gear ratio.
no worries man, that's why it's here!I hate to dig up old threads, but this is exactly what I've been looking for. I've been interested in 3D printing for a while and I'm leaning toward building my own very similar to yours(Like I need another project to take up my time...). I really like the idea of building a 3D printer that might be upgraded or serve double duty as a CNC router one day. I've got a few questions though.
How did you decide on the size? It seems to me that when DIYing a printer, there's almost no constraint on size other than possibly the lead screws (I haven't looked at these very much yet). Otherwise, slightly longer pieces of aluminum and drive belt shouldn't be hardly any difference in cost.
Also, everyone seems to use this extruded aluminum for the frame. I get that most of the 3D printing community doesn't have the same capabilities as this forum, but I would think that using steel square tubing, and welding it together might make things a fair bit stiffer/heavier particularly if it turns into a CNC router.

you could make a steel weldment but you may have a very hard time keeping everything flat and planer when welding
