Controlling PWM on the E1 heater.
-
Can you post your entire config.g?
-
@phaedrux sure can...just so you know, though, that extra header1 line was gone after restart, but still no berd activity. I did make sure the motor worked by connecting to 24v directly to test.

Are you running firmware 2.02?

@dc42 It appears that I am running 2.01. Is that a bad thing?
-
@crchisholm might not be a bad idea to update to 2.02
-
@phaedrux I have started trying to understand the process of upgrading the firmware and have determined that I only know enough to get myself into trouble. There is a lot of docs on this, but they are kinda going in many directions at once, and until I get a better handle on this, I am not going to do the upgrade from 2.01 to 2.02.
I ordered a PWM controller from TheMakerHive which should allow me to hook the air pump directly to the p/s and control the speed though that control. It's the cowards way out, but I have gone to very great pains to get as far as I am have and I just not confident enough to make the leap.
I will come back to this when I grow a pair

@crchisholm Upgrading to 2.02 should be quite easy. I think all you'll need to do is upload this single zip file through the DWC settings tab upload files button. Don't extract it or anything first, just upload the whole zip file. The system should ask you if you want to update the firmware and restart. It will update the firmware, the wifi firmware, and the DWC all together. Easiest Duet update yet.

Ok, I think this might be one of those cases where the only thing as bad as lack of info is too much info. I just got a little over-whelmed.I will go ahead and do the firmware update tomorrow. Thanks for the encouragement.

In my reply to the very similar question on the RepRap forum (which I assume was also from you) I mentioned that you need to use firmware 2.02 in order to be able to map a fan to a heater output.

Please forgive me. I am visually impaired and must use very large fonts, so what might be a half screen of info for someone else might be four screens worth for me. I miss things sometimes. I will try to be more careful.
-
I went and checked, and you are right. I completely missed the part about v2.02. I am very sorry.
-
Holy cow!!! It worked just as you'all said it would. And the firmware upgrade was VERY easy. As soon as the update was complete, without changing anything else, I tried the fan and I could control it using the fan slider.
Thank you all VERY MUCH!!!

Glad it's working.
