Being able to pause a print without it just sitting there melting your piece is a necessity nowadays, the included screen was $9 the graphic one that unlocks that feature and more was $13.
And again, nowadays having a parts cooler is a necessity, most everyone plays with PLA, and people are obsessed about perfect benchy's and other models without supports (looking at you groot)- a cooler is enough to make or break certain prints, I can tell you as a consumer, I passed up this printer 3 times because it had no parts cooler as small as that may seem.
When people do reviews, they base it on the machine as it sits, not by it's potential, and unfortunately, when you compare this machine to even a cheap chinese ender or the like, test prints may favor the cheap printer just because it had a parts cooler.
You can go online and find all the drama surrounding the lack of parts cooler.
And no, I don't fault the printer with the driver issue, I have suspicions my M.2 SSD is beginning to have segment issues, And I don't have any doubt Folgertech will fix the issues with the defective FT-1 and FT-2 pieces.
I'm glad I bought an FT-5 this is in no way a rant on my issues but rather constructive criticism.
I know about this as I am planning to release a race drone frame soon, I sent one into a racer, and he picked it apart, 3 revisions later and I think I have it where it will work in the market, however, due to demand people want TPU canopy's VS top-plates, I hate canopies, but to make people happy, I've been working on it, slowly, because I still am teaching myself 3D design, I would love to make and share a parts cooler, but I think it's still outside my skillset.
Oh, and just so you know, I believe there is a missing step installing the Y axis cable chain.
And one last thought, Since is without a doubt an advanced kit I think it would be wise to offer this machine as a bare kit with only a hotend and heated bed and charge a few bucks less.
