Your slicer gcode settings are not up to date. Learn more about the RatOS 2.1 Slicer Configuration
I copied and pasted the Cura specific slicer settings, but I still get this error message. Anyone know why. Also, shouldn't the skew profile also be in the printer settings in Cura?
Solution
Because the "Incomplete Slicer Configuration" error is only triggered if
TOTAL_LAYER_COUNT
TOTAL_LAYER_COUNT
isn't passed to START_PRINT. Ie, your custom start gcode in your slicer profile isn't correct. The doc has everything you need.
