This will no longer be updated.
Go to my website for the latest version and instructions. If you already installed this, you can go directly to the GitHub repository for the newest files.

Old description below.

These are the G-code snippets that belong with my PrusaSlicer (Slic3r) profiles for the FlashForge Creator Pro. Although I think the G-code is quite mature now, it is possible I will update it separately from the rest of the profile. Therefore use the ‘Watch’ button to stay notified of updates.
If you want to be on the bleeding edge and get the latest changes even if they are not significant, these G-code snippets are tracked in a GitHub repository.

If you see that only this G-code was updated, you can in most cases copy-paste the updated snippets into the printer settings section of PrusaSlicer as explained in my article. However, check the ‘Updates’ section below to see if you don't need to do anything else like enabling certain options in the printer profiles.

This code has the following features:

• Z homing with the same speed as plate levelling procedure
• Reliable tool change when printing with left extruder
• Only heat nozzles to 140°C while waiting for the bed to heat and then continue heating, to avoid baking filament inside the extruders when the bed needs a long time to heat
• Before printing the priming line, chop off ooze on front edge
• Extrude a line across the front of the bed to prime the nozzle
• Do an extra wipe on the extruded line
• No dubious fiddling with stepper VRefs

It may be possible to adapt this code for other slicers like Cura or Simplify3D if you know how to substitute the parameter names. However, for Cura you would need to remove the relative E commands because it only supports absolute extrusion coordinates.

(Again, I attached an STL file just because Thingiverse only allows Things with some kind of 3D model.)
