Since today's podcast highlights it, here's my experience so far. I got the machine Sunday and it's been running near non-stop printing holiday stuff (attached photos of a grinch hand decoration and multicolor ornament - all ABS)
1 - printing ABS on this machine is an absolute dream. I've attached photos of a Grinch hand wall hanger, printed in Polymaker ABS on the engineering plate. I printed all parts separately (non-AMS version), multi up filling the build plate. The hands took about 14 hours with a .6 nozzle, (.4 would have been over 20) came out fantastic. Supports snapped right off (unfortunately I didn't have any ABS support material). ZERO smell and my VOC meter didn't budge the entire time. Leaving the prints inside for about 5 minutes after print so the chamber can filter, and even opening the door the smell was about gone. Bambu has done a fantastic job with the chamber filtration on these. Some of the parts I've printed look damn near injection molded.
You guys were right when you said if you print a lot of ABS you should probably get the H2 machines. Or other materials, short of something like PEEK of course.
2 - I'm finding big time savings (for my usage case) with the Vortek/AMS combination in the front end. I have 3 AMS units - 1 AMSHT (single slot) and 2 full sized AMS units. The convenience of simply selecting a nozzle size and hitting print is a boon.
3 - The engineering plate is sublime. I hate textured PEI, the engineering plate has just a slight texture (like fine emory cloth). ABS sticks to it like glue (I use a little Dimafix liquid)
I also have the cutter head, which is going to replace a Silhouette Cameo. Already, Bambu's software is far more intuitive. Almost makes me wish I'd have sprung for the laser unit.
Build quality seems more like something that should cost $15K. Seriously, these H2 units are solid.
A few things annoy me, like the safety key in the rear - either put it on top or sell us the remote key separate from the laser. A stop button that only works with the laser - I see a future firmware update making it a sleep button like they did on the X1.

DANG Bryan - I am Totally DROOLING over this printer and your Posting! I'm so TOTALLY STOKED that This printer is GREAT with ABS! For Very Obvious reasons - for those folks that know me.
And - your Grinch Items are Insanely AWESOME!!!
It looks to me as though you obviously Acetone Vapor Smoothed the parts. Am I wrong???

I just opened your pics in another window - so it opens up like full screen - GREAT Stuff.
I'd Love to print the files - can you point us to the STL's?
Since - Yeah - I can indeed print ABS on my Elegoo Carbon!

No problem Kurt, the files are on makerworld:
https://makerworld.com/en/models/1891706-the-grinch-wall-mount#profileId-2026468
Click the arrow next to "open in bambu studio" for option to download STLs.

Make sure we get some pics!!
I printed the "no ams" version which splits the arm/cuff/sleeve into three parts. Unfortunately, they didn't include pins to help register, maybe download the normal version and split the cuff off in Orca which can add those in. Although working in ABS with Testors glue you have time to get it right before the parts weld completely.
Here's a 4 color ornament I printed a bunch of for the kids, also can be found on makerworld: (realized I didn't attach it)

Printed face down. Black was on the left hotend, the other colors were in the AMS switching on the right side (the vortek side). I took one to work to give to a buddy, he asked where I bought it haha.

Thanks dude!
So - you used Testors to put the parts together? Still - it looks like you did Acetone Vapor finishing on the parts. Am I wrong? They all look TOO Shiny & Smooth to NOT have done that - and it looks Great with the Shine!
AS for - "I took one to work to give to a buddy, he asked where I bought it haha. " - that's Hysterical!!!

Nope, just printed and glued together. The hand I printed with the .6 nozzle at .18 layer height, the sleeve and cuff were .4 nozzle at .2 layer height.
The generic ABS settings work perfectly for Polymaker ABS.
