Many technical flaws and terrible support
The Max4 has multiple flaws and errors that make it impossible to rely on it. Technical support has been unable to fix any of the issues I’ve had with the printer. Many times I sent an email request for help; in response I get a request for logs or other info. I send them the requested info and then I get no response for weeks. One example is that the web site tells you how to add custom filament types in Qidi’s software. What it doesn’t say is that you cannot print those added types if you have the Qidi box that came with the printer (at least that’s what support told me).
