Speed+1 pts
I'm in the same situation as you. I finally went ahead and ordered one since there are lots of sales this month, and I'm waiting for my shipping notice. It's strange and a bit concerning to me how little attention this printer has gotten. ModBot and mpoxDE (German) have the best YouTube coverage I've found. Here's what I've learned about it from digging through their forums and various videos. Ping me in a month for my own actual experience...
First, to the "Just get a Bambu" people, I find an IDEX compelling as I have no interest in the time and material waste of a single-extruder multimaterial system, though I totally respect the ease of use and speed. I look to the J1s for being at least as fast as my current Klipperized printer, relatively quiet and compact for my apartment, and auto XY calibration (an IDEX pain). I mainly want the ability to print different support material, and easy two-color or copy mode printing are happy bonuses.
The good: The J1/J1s seems like the only game in town next to the Sovol SV04 for IDEX in this range. That has, I think, bigger build volume but appears too large (for me) and more finicky. The J1 is quick, sturdy, pretty, relatively quiet, and in principle takes care of the especially frustrating IDEX XY calibration for you. First impressions from video reviews are very positive, and it can really do multi-*material.*
The bad: In reality, forums suggest the J1 attempts to be more user friendly and succeeds in some ways, but is still better for someone with 3d [truncated]
