3.2b4.1 - mini5+ +SBC - incorrect config-override

[jay_s_uk]

The values stored from tuning in config-override are incorrectly formatted.
They save as

M307 H0 R0.219 C520.500:520.500D2.20 S1.00 V12.2 B0
M307 H1 R2.343 C174.100:152.700D7.00 S1.00 V12.2 B0

There should be a space before the D value.
