I’ll be able to print them in PETG for you once I get through making face shields. I’ve got pretty good profiles dialed in for high-speed PETG now 
I do like the two lead screws with it integrated motors. And Marlin now has the ability to use a BL touch or probe and run those two motors independently to automatically tram the bed. You use one of the stepper motors on extruder2 to port on the board. You need one extra stepper driver (rather than running the two motors in parallel) but it’s a pretty small cost for a nice benefit.
