Create e table for each Thermistor about repetier-firmware

[repetier]

Hi,

I just wanted to inform you that the new development of the firmware
makes good progress. It now includes up to 3 generic thermistor tables
with equidistant temperatures, new temperature control with floating
point pid and a new pid autotune command M303 P0 S.

Version is already usable but you need to chech uiconfig.h as it is
enabled in dev tree.
There are also many other changes like new faster path planner and many
more, so if you already want to play, go on.

check upgrade_instructions.txt if you upgrade.

Yours
Roland

I would love to have a temperature table created at startup for each
Thermistor. I would never more have to deal with temperature tables
again...

Generaly parts come from different suppliers and it is quite common to
have at least different thermistor for the heated bed and the
extruders. In my setup I use different pullup resistors optimysed for
each temperature so that I can get 1/3 ºC resolution.

I have made some errors calculations and tables can be very small
while keeping errors within a maximum of 0.3%. The heated bed table
could also be smaller, it needs no more than 150°C

We could work out a minimum table length qeepink the error small. Feel
free to contact me in PVT
