You need `M306 T S1` to do a straight differential tune.

Hmm, looks like the "Automatic Differential Tuning" part of the docs has a few errors. I also see some math values that don't have enough $ signs and are not...

Could you include the text that was replaced by `[...]`? Also: the values this tune gave are all about 80% of the previous values. Did you use the same power...

Okay, so... - `M306 TD` is incorrect and the documentation needs correcting. - `M306 S1` works and gives very plausible results (for comparison my CHC hotend has MPC_BLOCK_HEAT_CAPACITY 5.54, MPC_SENSOR_RESPONSIVENESS...

It turns out there are several other bugs with the S1 tuning. Fixes for all of them coming soon to a PR near you.

A slight clarification on `MULTISTEPPING_LIMIT`: it is mainly there to prevent multistepping causing missed steps. If multistepping exceeds the microstepping setting for your stepper driver then there is a good...

> `time_spent_out_isr = 0;` gives no noise. This is an excellent test in terms of the information it gives. It tends to confirm my suspicion that the noise is from...

Idle because we talked about it at https://github.com/classicrocker883/MRiscoCProUI/issues/27

#27489 is a duplicate of this issue. I, too, have dual Z axes and TMC2209 but do not have the problem. The primary difference that I can is is that...

Okay, @moriamoria, @anomalchik and @Sanguium here is something to try: Change the file `Marlin/src/HAL/LPC1768/fastio.h` as follows: Remove `#define _TOGGLE(IO) LPC176x::gpio_toggle(IO)` and replace it with `#define _TOGGLE(IO) _WRITE(IO, !READ(IO))` Does this...
