I got significantly better layer stacking with my Delta with LDO steppers when i upgraded from OMC (same as ones linked above).

Filastruder carries them.
@CJD are you using a COTS pendant or one of your own design?
The real Mosquito has all kinds of problems with jamming with pla, even with a fan. The forums and discord’s are littered with people complaining about mosquito pla jams. It’s either heat creep or too small diam tube.
Pla is a difficult case because its hdt is so low, but it’s ironic that the most expensive hot end can’t reliably print the most common cheapest filament
See Klipper’s implementation of endstop phasing. It remembers microstep count at end stops during calibration. Subsequent endstop hits move to the nearest micro stop count same as set in calibration.
I haven’t used this so I don’t personally know how it performs. Have heard anecdotal reports of it being accurate enough to make delta bed probing unnecessary.

Klipper also has a TUNING_TOWER command. Perhaps a tuning_tower gcode could be implemented.
MXXX P’MYYY P<Val>’ Lmin Ffactor Bband
Where MYYY P### is emitted for each layer. Might require some slicer conventions to indicate layer start. Could also just emit this when Z changes, unfortunately including z hops...
Klipper doc:
TUNING_TOWER COMMAND=<command> PARAMETER=<name> START=<value> FACTOR=<value> [BAND=<value>]: A tool for tuning a parameter on each Z height during a print. The tool will run the given COMMAND with the given PARAMETER assigned to the value using the formula value = start + factor * z_height. If BAND is provided then the adjustment will only be made every BAND millimeters of z height - in that case the formula used is value = start + factor * ((floor(z_height / band) + .5) * band).
Check out Kisslicer’s <TUNINGVAL> wizard. It’s perfect for tuning gcode configurable settings.
Something similar can be done in prusaslicer now that they support expressions in gcode. Something like: (on phone so will gets syntax wrong)
Gxx P{min + (max-min)*layer_z/height)
Where you wish to interpolate the P parameter from min to max over the height of the test object.
Ternary operator like the c language ? :
Very useful for doing machine specific parameter substitutions vs having to do if then else.
Min, max functions
Max z of the current print job. Useful for doing tuning of parameters. That, or an interpolate with z function. For example
M572 DO S%zinterpolate(0.1,2.0)%
which would be the same as
M572 D0 S%0.1+(2.0-0.1)*z/max_z%
Are Motech and LDO the same?
Could very well be. or could be matched specs and China copying China. Motech and LDO are about 100km apart from each other in China.
