4 Part cooling fans for one tool??

  • I have 4 part cooling fans I would like to use for a single tool. I currently have them plugged into Fan 0, 1, 4, and 6. It also uses 4 heaters. The heaters and thermistors are working properly, as well as their respective heatsink cooling fans. I can't seem to figure out how to get the 4 part cooling fans to work together though. Is it possible to use a M563 command to designate these fans?

    I really don't want to cheat and use the F0 port to control relays!
    Any help would be greatly appreciated!

  • As far as i understand, it should work if you use M563 something like this:

    M563 Px Dx Hx F0:1:4:6 (x of course numbers you need). You probably need also to disable thermostatic contol of those fans before assigning them to tool.

    If you will always want to turn them on and off together, have you considered connecting them in parallel?

  • @dc42 will one fan pin be able to support the current of 4 fans? If not I could use it to trigger a relay that uses supply voltage but this method just seems like cheating to me haha. Ultimately I guess I could try that though. I'll try the M563 F0:1:4:6 first though, but is the colon to denote like 4-6 or is that 4 and 6?

  • Its 4 and 6, so in your case 0, 1, 4 and 6.

  • Thanks @aidar I'll try this today!

  • Thanks, this worked perfectly, just adding the F0:1:4:6 to the end of the existing M563 line. Awesome!
