      Hi guys, I am new here and just got my BLV mgn cube working with Duet3 and RRF3. Very proud of this piece of equipment!

      I have a little issue with parallel fans which are used for the x/y motor cooling. They do not start itself and I need to touch them to spin, then they keep on running.

      I did not find any info if the frequency is related to the power? Is there any other parameter which could give it more power?

        @snagit007 add a blip value to the M106. E.g. B1

          There should also be an S value on that line to tell it what speed to use when the temp is reached. S1 would be full power.
