Number of fans limited by firmware?

I can increase MaxFans in the next 3.4beta.
That would be cool! I guess there's a good reason for these limitations but I am sure the Duet can handle this.
@peter247 Neopixels are kinda expensive compared to "normal" LED strips and I'd like to be flexible.
@Phaedrux Did not know you could do that, thanks!

@dc42 Hey dc42, I know minor issues like this are not exactly a priority on your list but any chance that this is now fixed in the new RRF 3.4.0 beta 2? I did not find anything in the changelog. Would greatly appreciate this small fix. Thanks!

@techni see if you can follow the build instructions, and modify the value yourself and compile. It shouldn't be too hard.
-
If any of these fans are turned on and off at the same time, just wire them in parallel, first checking of course that the driver can handle the total current.
-
@techni I will increase the maximum number of fans to 20 in the next beta.

@dc42 Morning, was this finally solved in RRF 3.4b3?

@dc42 Many thanks!

I have an application that needs 24 fans. Is there a means to do this? I'm running a 6HC MB with 7x 3HC extension boards.

@timmacey currently (using RRF 3.4) you could only be able to control 20 at once as fans, but you could configure the remaining 4 as GpOut pins and control them using M42. I can increase the maximum number of fans in RRF 3.5.

@TimMacey the maximum number of fans was increased to 32 in RRF 3.5.
