sav mk1 extruder fan

boelle

i got a funny problem after i downloaded firmware and started from scratch

when i clik the botton in repetier host to turn on the fan nothing happens

but if i do a M42 P16 S255 it turns on

pins section for my board looks like this:

start of config....

#undef FAN_PIN

#define FAN_PIN -1

#undef FAN_BOARD_PIN

#define FAN_BOARD_PIN 40

i have a fan on pin 40 to cool the electronics.... works like it should

noticed in log:

21:00:47.760 : Unknown command:N8243 M106  S255

21:00:48.580 : Unknown command:N8244 M107

Repetier

#undef FAN_PIN

#define FAN_PIN -1

this removed fan control from firmware. Should be

#define FAN_PIN ORIG_FAN_PIN

to work as expected.

thanks a lot... 

btw... how much is there to gain for a normal 3d printer (not delta) to reflash firmware with the same settings but just newer copy of firmware?

You should check on github the commit history for work092 to answer that, In most cases nothing if you are not affected by the bug or have no need for a new feature. So as long as you have no problems you could skip many updates and do it only every few month to get fixes. We increase version when we had some new features that might be of interrest. In config tool you see it at the orange marked new parameter.
