GCode Header

At Hyrel, we believe that you must start with a good GCode header to get a good print. Below are explanations of our standard header files. These can be configured in Slic3r under Printer Settings > Custom G-code > Start G-code

Sample Header

• BLACK entries are for every machine
• GREEN entries are recommended, but must be manually entered
• RED entries are for the EHR only
• BLUE entries are for the 16A only
• PURPLE entries are explanations
• GOLD entries are optional, but recommended

This is what your header recipe will look like in Slic3r:
