    I have the R1+ and am waiting on my shipping for my R2. I can print small stuff in ABS on the R1+ but anything larger than about 50mm curls badly. I have tried many things with temp and make-shift enclosures, but nothing has made it any better. I am wondering if anyone is using ABS on the R2 yet, and how its going with it.

    Still effectively an open bay printer, but not as open as the R1 series :)
    At a guess I'd say printing it will be much the same (not a heated chamber after all).

    Perhaps someone has actually done it and can chime in. It has been forever since we printed it (too many better alternatives).

    Well, now that requires me to know why you wanted to use ABS :) What property (or combination of properties) does it have that you want. I assure you it has NO property (or combination of properties) that is not better in an alternative with possible exception of price.

    Material science ! There are a LOT of choices out there these days too.

    I've just bought my first roll of ABS filament. I was hoping it would work nicely with the R2. I'll see how it comes out next week.

    I've done this big one, key was the huge brim (20mm or so).

    That is beautiful! Did you go and edit some settings in Cura to make the extra big brim? I’m very new to 3D printing.

    Possibly, don't remember... On the right when you're in "Custom" mode each category title has a gear icon that appears when you hover the mouse over the category "title". Click that, and you'll get to a page where you choose which subsettigns should be visible. You'll have one that's Brim width, tick it to add it to the visible stuff.

    I've also made a calibration cube also with a big brim that came out nice. That's all I've done in ABS so far, rest is PLA / PETG / TPU / wood / copper.

    Kinda still don't "trust" ABS yet though so if I have to make something I don't want to risk too many failures like now I've got to do something for a customer for tomorrow I just throw PETG.

    I added a hood. ABS prints well for me now, without curling.

    The R2 is my first printer and I have not printed in ABS yet. I got a spool of ASA though and have had successful prints with it. I have had no warping and no layer delamination at all yet. I am printing at 245C with the bed at 80C. Only important thing is to use glue stick (haven't tried spray net yet) on the bed as ASA is almost fusing to PEI otherwise. I know as I made a ding in my bed trying to remove my first ASA print from it, while totally destroying the print... I got ASA instead of ABS as it is supposedly ideal outdoor being weather and UV resistant and will not yellow over time.

    One lesson learned: when using a hood similar to the one above: don’t think the PLA printed filament tube clips will hold up to the heat in the chamber. See orange clips in attached photo. I’ll have to reprint them in ABS. Makes sense now, but not at the time.

    You can use BluPrint since it has a higher transition temperature than ABS or any other higher temperature filament.

    Wow, those clips are not the gcode my machine had on it. I don't even know what mine was supposed to really look like as it came out totally fused to its supports that were encasing it.

    An error in an update messed up and replaced the correct clips file by a meaningless thing nobody knows what is.
