Got a question about updating firmware on my Ender 3 Pro running a 4.2.2 (non silent) board to the 4.2.7 silent board.
I recently updated to a Micro Swiss NG Direct Drive Extruder and All Metal Hot End and ran into an issue with extrusion quality. It seems the non silent drivers on the 4.2.2 board cause the extruder to pulsate causing crappy extrusions that are quit noticeable.
Micro Swiss confirms they have seen this issue on Creality 4.2.2 non-silent boards and their direct drive products. They said customers have tried TL Smoothers on the extruder or upgrade to the 4.2.7 board. They said the TL Smoother is hit or miss, but a board upgrade resolved it.
I added an BL Touch to this machine about a year ago and needed to update the firmware so I downloaded VS Studio and at that time the Marlin 2.0.0 Bugfix version, compiled and flashed the printer with no problem. Then this spring I enabled a couple more features and recompiled. The firmware has been running fine since.
So now that I’m installing a newer board I am contemplating downloading the latest version of Marlin and rebuilding the firmware (actually I change computers since the last compile and need to reload the software). My question what is the correct way to find all the customizations I’ve made to the current Configuration.h and Configuration_Adv.h and be sure I get these updates applied to the new config files?
I know there is a Creality firmware version (that supports BL Touch) on their web site, but I’m leery about what options or settings are enabled.
