Creatality Ender 3 – Custom start gcode for Cura Bed Leveling and Clip

I have a Creatality Ender 3 3D printer I have upgraded with a 32 bit silent main board, glass print bed, and a BL Touch auto bed leveler.

Using the firmware from Creatality for the new board did not work at all. Nor did default start code. I was having trouble getting the bed leveling to work, the tip to deblob, and for the print head to avoid the clips for the glass bed.

After much trial and error I got a working Marlin Firmware installed on the new board. The final win was updated start code for Cura. Here is my custom start gcode that does the following:

  1. Preheat bed
  2. Preheat extruder during setup
  3. Levels the bed and enables leveling
  4. Draws the starter lines avoiding the clips for the glass bed
  5. Deblobs the tip
