Have you opened a ticket with them and tried to get help with troubleshooting? If you consider that likely a vast majority of Raise3D owners are not on this forum, saying everyone should get their money back or file class action based on such a small fraction of owners with this issue is just completely flawed. I get that you are frustrated, but your claims of widespread issues/design flaws are based purely on a very shortsighted observation with an insignificant sample size. Is there something I am missing here?

I have used a Pro 2 Plus for a year now with none of these issues. I have printed with PLA, ABS, NylonX, Taulman Alloy 910, PVA, PolyFlex TPU, etc. I have printed parts that range from 10 minutes to 4-5 days print time. I have yet to have a failure that I would say is the fault of the printer. Some materials are easier to work with than others, but this is by far my favorite printer that we have here. This includes a MakerBot Replicator+ (worst decision ever and only $2,500), this Pro 2 Plus ($6k IIRC?), a MarkForged that lays fiberglass/carbon fiber strands ($80k), and a Fortus 450MC, which was an insane $250k. I haven't found a single part thus far that was worth printing on the MarkForged or Fortus. Why don't I have these issues if the root cause is "bad design"?

What PRO2? What version? New has bigger heatsinks... no warranty action or even replacement event so... I was struggling 3 years with it. With 0.6 nozzles machine perform very well without issue right now. Now I'm not the owner of Raise. The machine was sold.

This sentence makes no sense whatsoever.

My experience reflects TaterMay's. One of the Pro2 Plus printers at my company sat broken and unused for a year. My 3D printer knowledge was minimal, but I repaired it in March and read the many instructional comments posted on this site. Once I got the (few) bugs ironed out, the printer has been in continuous use for the last six months without a clog or other problem. My print accuracy with .4mm nozzles has been rock-solid with very tight tolerances - again this is due in large part to reading the posts here and making the necessary adjustments. For those of you who help each other out with your expertise, there's a much larger ripple effect that benefits the entire Raise3D community. Thanks to all of you who have made it easier for me to achieve consistently good results by sharing your experiences.

Unless your (ex) printer has (had) unresolved mechanical or alignment issues, the Pro2 Plus is capable of reliably creating very accurate prints with NO modifications. You just have to be smarter than the equipment you're operating. The more you know, the easier it gets to detect potential issues and resolve them.

Unfortunately, 3D printing is not plug-and-play yet. Owners are required to have a deeper depth of knowledge of how the system operates (hardware and software) and be able to perform their own repairs.

The Pro2series has room for improvement - and some owners have modified theirs for their particular situation. Changing nozzles, (not that I need to do it much) is harder than it needs to be, but at some point, quick -change hot ends will be the norm - not the exception.
I'm not holding out for Raise3D to come out with an upgrade package, though that would be much appreciated for anyone wanting factory-approved modifications. It isn't an admission that the old design is inadequate, only that it can be improved.

I like the seamless integration of ideaMaker with the printer; the software continues to improve with time, but I hope it doesn't become bloated with excessive features in an attempt to please everyone.

Я согласен, но согласитесь, это плаксивый пост.
