Flagship machine is trash! Not one day goes buy without a failed print due to a non existent error or bug. only had the thing for a week and it was down 80% of the time and ruined equal amount of prints that took days to finish with pounds of filament waist. looks like customer service is trash based off the last couple of posts i have seen. If you promote this product in any way shame on you. this pos is getting sent back tomorrow morning. Flashforge is already on its way. m!n
