PINDA simulation

Simulate the PINDA.

Not only the pinda, but also the other 5 axis ends.
And just as a bonus, maybe also a way to trigger crash detection.

Good point! (Though at least for the X/Y endstops I think those are going to be part of the motor simulation, e..g if the tracked position <=[MIN_VAL] or >[MAX_VAL] then we fire an endstop signal.

Seems like that's the first step along the road to implementing a simulated sensorless home :-)

Update - the thermistor is wired in, so now this task basically boils down to packaging that aspect together with a "button" as an endstop (and with an input IRQ that can be wired to a simulated motor to fire at a given Z height)

[vintagepc]

In my TMC branch I've temporarily wired in the Z min endstop to a min out flag on the TMC simulator.

Longer term it would be good to make the PINDA have customizable trigger heights (e.g. cycling through a list of them) to make it easy to simulate various MBL conditions.

I'll take a crack at this next. I think I'll make it so that you can give it an z/y/z map to simulate a given bed level scenario and wire it to the position inputs so that it works regardless of what the probe sequence is (e.g. 2 measurements per point vs 5 measurements, 3x3, 7x7, etc).

XYZ cal pass!

Just tested the new XYZ calibration. Very nice!

[vintagepc]

Thanks! I'd never actually had serial connections open when running that so it was kinda cool to see it mapping out the bed over the terminal.

(Definitely helped debugging it too, had to alter the z-trigger function coefficients a bit to get it into a shape that it liked. )
