The best #tech #support of any company I've ever interacted with comes from Prusa, the Czech #3D #printer maker. Consistently, they listen to what you have to say, and right away have a good answer. No how-are-you-doing-you-are-so-important-to-us bs that only aggravates everybody, but straight answers to each question, always backed up with links, sometimes with more background info than you had any reason to supposed might exist.
3D printers are fickle and need maintenance, so I have contacted them a few times over the years, and it's always been excellent.
Interested in 3D printing? Maybe buy from them just for the support.
P.S. I like the printer I have a lot, too.
