Instead of adding a momentary switch to fake the insertion of the card I have modified the ultralcd menu item:
Card Menu -> Refresh
to reinitialise the card providing that the SDCARDDETECT pin has been set to -1 in the pins.h file. This requires one less switch on the front panel and the refresh menu item is in the most relevent place for a user who wishes to inert a card and then print from it.
It also means that the "Card inserted" messages do not bother the users of these card readers (they dont make sense for users without SCCARDDETECT)
V1.4 moves thermistor power to the always-on 5v line.
The BOGUS_TEMPERATURE_FAILSAFE_OVERRIDE is no longer
needed on this board. Add a new motherboard type to
support this feature.
The code to ignore the "bad thermistor reading failsafe"
suicide function depends on the existing of the PS_ON pin
feature. But in some boards this shouldn't be the case
Fix this by adding an explicit definition to make our
intentions more clear and separable.
The Z_MAX_PIN value was defined as no-value, but this causes
the compile to fail. Fix this by setting the Z_MAX_PIN to the
correct value (which happens to be 0 for pin PB0/DIO0/0).
I find that the PID routine works better when the cooling fan is switched on
at the beginning of a warm up routine. Otherwise when you enable the fan
just before a print, you have a delay as the PIDre-adjusts.
This should also be safer as most cooling fans are directed at the hot -ends
thermal barrier!
Instead of a single pre-heat, now there is pre-heat ABS and PLA options
Added defines to the configuration file to adjust preheat temperatures for both
