Best practise G-codes

These custom G-codes are necessary to get the best user experience.

Layer Count

To have Slicer layer counts in Mainsail, you have to add these two G-codes in your custom G-codes in PrusaSlicer:

Start G-code (before your start G-code):

SET_PRINT_STATS_INFO TOTAL_LAYER=[total_layer_count]

After layer change G-code:

SET_PRINT_STATS_INFO CURRENT_LAYER={layer_num + 1}
