We have this android PCB replaced 5 months ago, because one day it just went blank and died. Since we are in Mexico the warranty doesn’t apply to us in the end we finally managed to get this part replaced but this week the printer started to stop suddenly, my first response was to change the USB because the original was is more than 1 year old and it indeed had some issues when read on PC. But after the change the probelm has happened 3 more times, blank screen with no info, we were producing a 7 hours print, and the printer at certain point decided to stop and restart itself. Many companies are using this devices for production. We have been zortrax resellers for 4 years, before they finished the agreement because sales target were not meet, however with such faulty devices it’s hard to do it and even more when they don’t give any warranty for the products sold. I’m currenlty on a huge problem because we are still selling this devices through a PR reseller, adn it’s been a week since I sent information via email one M300 plus is dead also, endstop error, readings are ok and no response from anyone. Even crappy companies like Prusa, Creality, and so on simply dispatch replacement parts without so much questions, if something from the propiertary electronics fails under the first year it’s clearly a manufacture defect, but zortrax thinks different and even thinks they have 1st, 2nd and 3rd class customers, being on that 3rd class everyone in the world except from EU and USA. Such a shame.
