3.0 Heater/Fan configuration
-
@dc42 I have installed new config files after running the configurator. I'm getting some errors with M98, but I'll see if I can work through those before I come back for more help. Thank you.
-
Did you stop at 3.0? You should update to 3.2.2 right away.
-
@phaedrux - was just going to get things working before taking it the rest of the way. Don't plan to stop at 3.0. Thank you.
-
The problem with stopping at 3.0 is that the pin defaults change in the following firmwares. So it's really not a good place to figure the config out.
-
I'm at 3.2.2 and things are in pretty good shape now, but I have one issue I can't figure out.
I have the hot-end fan as Fan2 to turn on when the hot end exceeds 40C.
M950 F2 C"fan2" Q500 ; create fan 2 on pin fan2 and set its frequency M106 P2 S1 H1 T40 ; set fan 2 value. Thermostatic control is turned onI boot up the machine, turn on the heat, and this works fine. There is not a control showing in the DWC dashboard.
I'm not exactly sure what triggers the change, but when I went to run a part, the hot-end fan doesn't start up - but in the Dashboard Fan2 appears, and the slider appears to override the thermostatic control and the fan doesn't run.
What do I need to change to have it temperature controlled and keep it from appearing on DWC?

Can you show a screen shot of what you're referring to on DWC?
-
@phaedrux @phaedrux This isn't from the printer in question, but here is where FAN2 will appear. It's not there when the machine first boots up and the fan turns on when the hot end temp exceeds 40C. I haven't done enough to know exactly when FAN2 shows up, but when it does it seems the fan no longer responds to the hot-end temperature.
-
The tool fan slider will control the fan of the currently selected tool.
-
@phaedrux FAN2 is the issue. That's the fan on the hot end. How do I prevent that from showing up on DWC? It should only be temperature controlled from the extruder heater.
-
Is you DWC also updated to 3.2.2?

I would suggest to rename the 2nd fan to F1 and channel to P1(UTC+1)

That would make more sense. Fan1 is the recommended port for heatsink fan.
-
@phaedrux I did not take separate action to update DWC - just dropped the big firmware zip in the system folder. If DWC requires a separate update, I will do that.

@diy-o-sphere
I did not wire the machine. Will poke my head in the control box to confirm how things are wired and if I might need to switch a couple cables. -

Change the config toM950 F1 C"fan2" Q500 ; create fan 2 on pin fan2 and set its frequency M106 P1 S1 H1 T40 ; set fan 2 value. Thermostatic control is turned on -

Normally uploading the full zip should update everything, but if you are using a very old version it might not get picked up I guess.
You can try uploading the DWC zip file by itself and if that doesn't work, use that zip file to replace the contents of the /www folder on the SD card manually.

By "run a part", do you mean run a print job from SD card? If so, then perhaps something in the print job is reconfiguring the fan - in which case, please share the print file.

I really appreciate all the help.
I changed the can lines per @DIY-O-Sphere toM950 F1 C"fan2" Q500 ; create fan 2 on pin fan2 and set its frequency M106 P1 S1 H1 T40 ; set fan 2 value. Thermostatic control is turned onFunctioning properly and not showing up on the dashboard slider.
The Z-Probe on this machine is accelerometer-based and that's a little flaky, but doesn't seem to be software related.Up and running now, so 'til next time ...
