Is it possible to turn on and off the hotend fan? Hi, I have a Duet v0.6 in Fisher. The firmware is RepRapFirmware-dc42 1.12a. I'd like to turn off the blower during the idle by creating two macros on DWC. https://reprap.org/forum/read.php?416,714353,714353#msg-714353 Tue, 16 Jun 2026 23:27:50 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?416,714353,715868#msg-715868 Re: Is it possible to turn on and off the hotend fan? https://reprap.org/forum/read.php?416,714353,715868#msg-715868 DADIY Duet Fri, 21 Oct 2016 02:33:24 -0400 https://reprap.org/forum/read.php?416,714353,715841#msg-715841 Re: Is it possible to turn on and off the hotend fan? https://reprap.org/forum/read.php?416,714353,715841#msg-715841 janpenguin Duet Thu, 20 Oct 2016 21:59:32 -0400 https://reprap.org/forum/read.php?416,714353,715724#msg-715724 Re: Is it possible to turn on and off the hotend fan? https://reprap.org/forum/read.php?416,714353,715724#msg-715724 dc42 Duet Thu, 20 Oct 2016 14:28:24 -0400 https://reprap.org/forum/read.php?416,714353,715638#msg-715638 Re: Is it possible to turn on and off the hotend fan? https://reprap.org/forum/read.php?416,714353,715638#msg-715638 It runs at constant speed until the power turns off. I also connected a 5V fan on the expansion pin to cool down the board.
I like to know RepRapFirmware provide gcode commands that control the speed of two fans.

"M106 P1 T65 H1; Thermostatic Fan will start while Heater 1 reach 65°C"
As can be found in the awesome Aquilegia help system:
