M200+ warm up takes ages

Can someone please tell me how long their M200+ takes to warm up and start priting. I have just been told by Zortrax that 8-9 minutes is fine from cold and 7 minutes is fine from 70%.

if you watch the tempertures and % it jumps about all over the place.

If this is the case … anyone want to buy 2 low usage, under 500 hours, M200+s?
