@bill.m.davis I have four single material Robox printers, the first model that came out in 2014, and three dual material units. I have used the Pro and it is also a good machine with some additional features that make it really nice, but I don’t have space for it in my shop so I haven’t gotten it. If I did, it would replace the Prusa machines. I don’t run as much printing work as I used to so I don’t have a way to justify the cost of the Pro.
@lightner You can print ABS and PC on the Prusa, just use the draft shield.
A fewer number of well-used units can give you as much or more information than a large number in my experience. A company also has to have a good marketing and manufacturing team to succeed. Those have been the Achilles’ heel for CEL. They didn’t get enough word out early and had some early manufacturing issues that caused problems. They got those under control and turn out a good product as far as I am concerned.
