Hi Guys. I´m trying to control the FAN of each Extruder individually, but sending M106 P0 S255 turns both fans at 100%. Am I missing something?
Using the SV04 panel is possible to turn just one of them off.
Yes, this is interesting & might be a bug…
The fan control behaviour depends on the print mode you selected:
In both single nozzle modes you can control the fans separately.
In copy, mirror and dual mode a single fan setting sets both fans.
From my point of view it should be different in the dual mode, where it is quite likely to have the need for separate fan settings.
I enclosed my fan test gcode.
FanTest.gcode (782 Bytes)
Like Bjoern said, it depends on the mode.
JohnCarlson’s SV04 FW (search GitHub) is able to adjust fans on the fly to different speeds also, but I only tested it in single mode so far.
Thanks, @Bjoern that didn´t work because I´m using the original SV04 firmware, which all is blocked. I´m trying to upgrade it to Marlin 2.1, and I´m facing issues with the Display DGUS.
I´ll keep trying.
Yes, correct: Displaying M117 gcode messages on the DGUS display is not implemented in Sovol firmware v1.1.0.
You will need either other display hardware / a rotary encoder or an additional DGUS display handling class to get Marlin 2.1.x firmware running. John Carlson did the latter & published his results & matching DGUS software versions.
@Bjoern, thank you for guiding me. John Carlson did an excellent job. I installed it, and it works perfectly. By the way, the visual of the Display is very nice.
Hello @Bjoern
I have tested with your fantest gcode and firmware 1.15.6
In all modes, both fans starts and stop at the same time.
On my machine M107 stops both fans, M106 P0 and M106 P1 start the 2 fans together.
Speed adjustment is fine … but the 2 fans together !
Do I have a possible wrong connection of the cables ?
Any idea
Hello pierre06,
recently your SV04 had a lot of hardware changes, hence connection problems are not unlikely…
Here you’ll find a pinout diagram for your SV04. A good starting point would be to check the correct fan connector positions on both gantry breakout boards - it should be K-Fan1 on the left gantry breakout board & K-Fan2 on the right side. Here is a discussion of a similar issue in the German forum & a solution with a firmware modification.
Good luck!
Björn
Hi @Bjoern Thanks for your message
I have verified that the breakout boards are properly connected
As I was telling in my machine your testfan script or the M106/107 does not work properly but besides I have observed that in the Temp menu on the display, I am able to control independently the 2 fans including start stop and speed at Zero temp or not !
Hi again,
I will re-run the fan test gcode on my SV04 at the appropriate time & keep you informed.
Hi @Bjoern , have you found time to re-run the test gcode ?
Hi again,
not yet…
