Marlin g-codes applicable for a Melzi Sanguino board How/where do I find a complete listing of "acceptable" Marlin g-codes applicable to a Melzi Sanguino board on a 3D printer (Zonestar). It appears that not all printer boards accept all available Marlin codes.



Then I was thinking incorrectly. I had assumed that not all g-codes (from a Marlin build) were, in fact, “implemented” the same way on all boards, and some would not even be recognized or interpreted. But I still don’t understand why that is.
As already written in the comments the software defines what G-Codes are taken by a (printer) boardBUT Even if the software has the same name (eg Marlin) it might behave different on different boards because of:


different release versions for different hardware
different release repositories being ahead or behind the master repo
hardware specific features a G-code triggers (most unlikely)


The clever way is to go from features I need to software supporting thosefeatures to boards supported AND useable for my hardware to controll (3d-printer/CNC-router/laser-cutter aso)
