We have plenty of customers that are also able to communicate with some of the Qidi models, so we are still trying to get clarity on which exact models and firmwares seem to be affected. For example, I just sent a wifi print to the X-pro and it worked fine. However, we also have an i-mate S on the latest firmware that does NOT work, so we know that is at least one combination that isn't working.
It has helped hearing which exact models are NOT working for people, along with the firmware version on those machines, so if you are having trouble with V5 please feel free to add a post including that information.
