I stuck at 205 C and difficult to go up again on my extruder ..

Thanks

Mine reaches 230 easily. Is it a 12volt resistor or 24volt?

Do you have the MAXTEMP set in your Configuration.h at 205 I suspect that this is your problem

relavent section pasted below

#define HEATER_0_MAXTEMP 275
#define HEATER_1_MAXTEMP 275
#define HEATER_2_MAXTEMP 275
#define HEATER_3_MAXTEMP 275
#define BED_MAXTEMP 150


These are lifted from the latest Ver on Github so may be slightly different in your version But I suspect that this is your issue but can't gaurantee it as I don't use Marlin at all and never could get it to work and gave up on it when I found Repeater FW.

HTH
