M42 P40 S255 ; Enable Fan Board
the new update does not work the command M42 to turn on fans
20: 15: 22,546: Errore: Pin non può essere impostata da M42, può in invalido o in uso.
use Alligator Board
M42 prevents use of sensitive pins (a list in pins.h). For fan you should use M106/M107 to change values.

pin to be inserted into the board fans start G-code
It worked well with previous firmware
alligator pin board 40
Just checked config and pin 40 is not used by alligator definition, so that should work. What wonders me is the error message which is not english. Repetier-Firmware has only english error messages, so maybe you are using Marlin?
am loyal Repetier DeltaPrinter for life.
PWM outputs pin 36,40,41
36 Board with fans start G-code
40 and reserved
41 for Light and command M355 S1

I have checked the sources and you get this message only if the pin number is in sensitive pins. FAN_PIN and LED_PIN get added to sensitive pin, so if you have set it to 40 and 41 in your pins.h you can not set it with M42 that is correct. LED_PIN and FAN_PIN have specific usages and are used by firmware so you need to use firmware commands to control them not 42. If you want M42 don't set them in pins.h.

I am sure that in the previous version all ok
I try to install version in May
I always had M42 P40 S255; activate Fan Board
My start in the G-code.
I almost burned the Board with the new version
with the temperatures
of these days
I Zprobe and Z-correction (distortion correction) everything works fine with M42
if not active have problems with answers.
Interesting thing since that should have nothing to do with the problem. That lead me to an idea what the real problem is. Seems like pins were stored in an int array which is treated as bytes causing it to test more bytes then present.
Please check if it now also works with newest update. I think that should fix the problem.
with the new update
