The previous video was supposed to cover both Starting and Ending G Code but it was getting a bit long, so I decided to cover the Ending G Code in a separate video – this is that video! In the first video I covered some G Code basics and where to set the starting and ending G Code in Slic3r, Simplify3D and Cura. So if you want those details see the previous video here.
I recently received a message from a subscriber who was having issues with their starting G Code and asking if I could send mine to them. I explained that Start G Code is fairly unique to a specific printer and the user’s requirements. So I created a video, linked above, detailing where custom start G Code can be set in Slic3r, Simplify3D & Cura, together with a description of the kind of things to look out for and insert in this start G Code.
I also mention a list of some common placeholder variables that can be inserted in custom G Code – to be replaced during export with settings from your profiles. That list of Slic3r, Simplify3D & Cura common placeholder variables is here. Please note that, apart from Slic3r, support and documentation from the slicers is poor to non-existent.
I will be covering the Custom End G Code in the next video as this first video on the subject was getting long due to having to cover the basics of G Code and the differences in the slicers.
Everyone knows that getting your first layer right is 90% of the battle to getting a successful 3D print. Even if your temperatures and everything else are correct, if your nozzle height is off you will get bad adhesion on the first layer.
Setting it up is actually pretty simple, but it can be confusing. In this video I explain, in very deep detail, what all the parameters and settings do that control nozzle height on your first layer so that you can get perfect first layers. In this video I am using a Cartesian style machine, a Prusa i3 MK2, and Marlin as the firmware – but the principles will remain constant for most printing systems.
