Slow down before endstop?

@thekm The slow down when using an analogue probe (like the IR probe) no longer happens in RRF 3.3 and later (and only works with Z probing afaik). Instead M558 allows the fast then slow probing. See under 'New features' here https://github.com/Duet3D/RepRapFirmware/wiki/Changelog-RRF-3.x#reprapfirmware-33
• M558 now accepts either one or two F values, e.g. F1000:300. If two values are provided, then when executing a G30 command with no P parameter an additional probe using the first speed will first be done to establish the approximate Z=0 position, followed by one or more probes (controlled by the A parameter) to establish Z=0 more precisely.
• When using an analog Z probe, the probing speed is no longer reduced when the probe is close to triggering. Use the new M558 facility to do fast-then-slow probing instead, if necessary.Also, not relevant here, but the IR probe is always in digital mode on Duet 3, because of the permanent pullup resistor. On Duet 2 it can be run in analog mode.
