New K1 MAX purchased to update from a CR-6 MAX type printer that is 2 weeks old to print corner extrusions. which allow 2 MDF boards to be joined at right angles. the CR-6 MAX type does a good job though 7-12 hours to print each one, using PLA+ The 3 times the price for the extra speed maybe the $$$ extra could have been better off with another CR-6 MAX or 2 Dunno.
