I am running Cura 5.6 on Windows 10. I just added a printer profile for the Ender 3 v3 ke. It is working fine except for 1 thing. I can't set the speed to 300mm or higher in the speed section of the profile I set up for this printer. The max speed that I can enter is 150mm. Anything higher results in the field turning yellow. If I ignore the yellow color and enter 300mm, the resulting g-code runs the printer much slower. I am guessing that the speed is 150mm. How can I set the max speed higher than 150mm? Also on another note, are there plans to have the g-code flavor set to klipper for a printer machine setting?
