Hi Tinker,

There are some menu items we disabled, including some prepare > preheat PLA and preheat ABS options. Are these the ones you mean? They caused some confusion on how to start a print among our early customers, and since the .fff profiles automatically set the temperatures in the print gcode, they're somewhat redundant. Couple of options if you want to pre-heat the printer before beginning the print:
  1. Use the Control > Temperature menu to manually set the bed and print head temperatures
  2. Send us an email at support@fusion3design.com and we can help re-enable the preheat options


Hope this helps!
Chris
