As far as I know, printing with ABS is always tricky, even with small printers. It is prone to warping and shrinkage and requires lots of precautions (right heated bed, enclosure, etc.). However, I am aware that printing big parts in one piece can easily turn into a total failure. Thus, I’m trying to find the machine with the best price/performance ratio that, with the proper prep, can print big without warping.
Thanks for you suggestion Pete! I had a look at David’s thread and noticed that one user asked him this exact question. Here is David reply:
“Basically I made the printer twice as tall and changed the firmware to that effect.
If you don’t do that, the printer still thinks that it is the original height!
I also took the x and y axis and put them on a gantry so that I didn’t have a build plate that moved back and forth.”
It required a bit of tinkering.
I also dived into the blog where I found the article about the big-bed printers (which raised all my doubts) and found a useful guide, which includes lots of info about 3D printer specs (what they mean, etc.) and learnt a bunch of useful things I would take into consideration for my next purchase. It tokk the modix as an example, and almost convinced me to buy the Big60.
