Same here.
I have a Creality CR-X. Dual extrusion with one nozzle. Thought I'd give the beta a go as it came with a profile for my printer. Results so far:
It still gets the prime tower print order wrong. It'll print layer 1 with T0 then print layer 1 for the tower also with T0. However it should print layer 1 for the tower with T1. Instead it simply retracts T0, feeds in T1 and continues with layer 1 causing massive colour contamination.
On tool change it rapids to the tower position, pauses for 10 seconds, rapids back to the print, rapids back to the tower, prints two perimeters of the tower and then rapids back to the print. (I might be able to solve this by entering a minimum extrusion volume for the tower.)
If I check Z-Hop I get a 10 second pause at every z lift and at the beginning and end of every rapid move. I cannot find a way of disabling this pause.
Already the 4.1 beta looks more promising than 4.0 but until these issues are remedied its still not usable.
