Hi all,
I'm Alex, 54, italian and I enjoyed 3d printing for 15 years now.
I bought a mks tinybee to replace my defective anet a8 board, but the problem is not the board itself.
I installed marlin 2.0.9.2 with no issue at all, for two weeks everything worked as expected but due to a short (my fault) to the thermistor ends while cleaning it, all
of a sudden i couldn't read temperatures anymore.
I found out that the readings where there, but using M105 it came out that my ADC values where offset somehow compared to the normal values.
So I patiently remapped the new values and rewrote them in the thermistor_5.h and now the board reads the temps correctly, but it does not allow me to turn on the heaters with a MINTEMP error.
Since my new thermistor table goes now from 1280 (1230 at 30°C) I guess that the mintemp routine has a sanity check somewhere not allowing me to go so high in ADC values.
I searched the code, but I didn't find where this parameter is set. (regular 100k thermistors start around at 1020 or so), does somebody have any clue?
Txs for any help
