How's it going? So let's see what we can see, here… According to the datasheet pin `PA3` is connected to `TIM5_CH4`. In Marlin the `STM32F103RE_creality` environment used to build this...

This has been brought up to date, cleaned up, and tweaked to conform better to Marlin S&P. Please work up a test compilation that succeeds and we can add it...

Check out the simulator work underway at https://github.com/p3p/Marlin/tree/pr_linux_cleanup and give it a run. It uses SDL and IMGUI and currently emulates both a U8GLIB-based DOGM LCD and the TFT version...

As I understand it there are situations when the spindle ENA pin ought to be left in the ON state even though the PWM is being set to 0 so...

- Please take a look at #22690 and consider working with @descipher to document the existing code and figure out the total refactor that is required to improve this subsystem...

In reference to my last commit… The default behavior should be to leave `ENA` turned on with `M3` and only turn it off with `M5`. Obviously, if only a `PWM`...

These macros append `_PIN` for us… ```cpp // Macros to support pins/buttons exist testing #define PIN_EXISTS(PN) (defined(PN##_PIN) && PN##_PIN >= 0) #define _PINEX_1 PIN_EXISTS #define PINS_EXIST(V...) DO(PINEX,&&,V) ``` … But,...

For homing the general recommendation is to use a larger `HOMING_BUMP_DIVISOR` for Z. Slow probing is known to greatly increase accuracy.

What kind of repeatability do you get with your probe? How out is it typically? What kind of probe design is it? I suppose it makes sense to have the...
