@HandyDoodads I like what you’ve done with the Start G-code. I’ve also checked that Sovol hasn’t published any new profiles ( just ‘[align profiles with Orca Slicer naming conventions](https://github.com/Sovol3d/Sovol-OrcaSlicer/commit/3fcbed7dad2483b8e3f7a32b22df51ce4a379244)’ on Aug 8 ). I’ve made the following tweaks: - used global variables to clarify starting purge position, as you suggested - Load skew compensation - (various ways to find this, I use CaliLantern) - Generally removed hard-coded values when variables are available in SuperSlicer (WIP) - Beginning to add support for other nozzle diameters (WIP) - - added @PicobelloBV [Chamber Temperature Control](https://forum.sovol3d.com/t/chamber-temperature-control/8577/4) via the exhaust\_fan - this requires changes to printer.cfg - this should NOT associated with the new [Chamber Heating Module](https://www.sovol3d.com/products/zero-chamber-heater) - this block is commented out for easy copy/pasting - rewrote the priming/purge lines for clarity - Purpose of the 10 segments appears to be for good purge lines without pressure advance getting in the way - There’s three styles of purges depending on the conditionals - long 10 segment near the part E1 - short 2 segment near the part, E lots - long 10 segment near the front edge. - All purge styles are tedious without jinja-2 or other loop implementation - Strongly considering abandoning purge codes in the starting g-code, opting either for a single loop skirt or a custom Klipper macro (common, but not part of Sovol) - Moved up M104/M140 commands as early as I could, and included the M109/M190 waits to save time per @sebastianha - originally it didn’t do much, but I moved up the initial dirty nozzle G28 homing so that it may actually save some time - I’ll be posting this whole profile to Printables as a remix of @TomsPrintGarden ‘s work. * * * ```auto ;
