I recently bought BZT PFL-3 machine but i have faced numerous problems using it. Among them are: i) EStop never worked. Its now disabled. ii) The axis now stall every other time. I changed motors and ballscrews but this only proved to be a temporary solution coz the problem is now back. iii) The spindle and M3 have stopped too. At a cost of nearly €5000 this provides terrible value for my money. I feel like taking the machine back.
