I sometimes need to level right before full bed long (3-4 day prints) to ensure the best possible print, in this I have developed the following start-print gcode for my printer, see below. But my question is about optimization of this, my probe is far left of the tool head preventing reading the right side automatically. Are there any other optimizations or something else to make it faster/more reliable/remove unneeded lines? I’m really just optimizing here so no rush just curious some about some expert opinions

@usulrasolas: I don’t have a TAZ 6, so I really can’t offer any recommendations specific to that model, but the SynDaver Axi does have a similar frame and uses a BLTouch. Here is the GCODE used in that printer, which could give you some ideas:
