The goal of the code is to do the following:

1. Warm the bed up to printing temperature
2. Start warming the nozzle to 160; do not wait for the nozzle to heat up at this point
3. Home
4. Run bed leveling
5. Warm nozzle to printing temperature. Wait until temperature is reached
6. Print a prime line.
