Issue configuring more than 3 fans with M950 #66

Closed AndyRap closed 3 years ago

Hi,

Trying to setup dual extrusion but I am hitting a snag when it comes to adding the fans. F0, F1 and F2 all configure and work correctly.

When I add the lines:

M950 F3 C"P1.22" Q500 ; Tool 1 Heatsink Fan M106 P3 H2 T100 B500 C"T1"

I get

"Error: in file macro line 65: M950: parameter 'F' too high"

followed by

"Error: M106: Fan number 3 not found"

I have looked around and seen configurations for 5 or more fans on authentic Duet hardware and the fact the I get the M106 error that Fan3 can't be found would seem to suggest that the firmware 'should' support it.

Is this a bug or a limitation in the port to LPC / STM32 hardware.

Thanks in advance

Andy Hodges
