I Just added the T0 and the next time I have this issue I will take a screen shot.

@phaedrux

Is there a command I can type when the temp isn't changing to see what the duet thinks it is told? That way I can find out if it is the duet or if the web interface is causing me the issue?

@dc42 said in How do I change the max temperature for my hotends?:

Thanks for the suggestions. I figured the problem out I have to set the temp 1c higher than what I want my max to be in my config.g file.

I have this in the config.g but it still will not let me go that hot.

As far as I can tell the temp isnt changing. The next time it happens I will set it to zero and wait a while to see if it is dropping and not showing or the temp is staying.

@phaedrux

Yes it is.

I have had an issue with my hotends some times not changing the temperature when I change it in the web interface. When it does this all I have to do to get it working again is to switch it off and then back on. So far I have only had the issue while I am heating up my hot ends to change filament and then I need to change them temp and it will just stay at the previous temp it doesn't matter what I set it to.

This is the firmware I am using.

I just tested it with out shutting the heat off and it works just fine, thank all for the help.

@fcwilt

I read if you do not turn the heaters off they can mess with the Bltouch's reading.

@stephen6309

Thank you that did the trick!

@fcwilt

No I am not shutting it off, it shuts off when the Bltouch prob's then it turns back on.

Also you may check that the fan you are using for you heatsink isn't blowing to hard, I was having that problem with my dual head setup. Slowed the fan down and then redid the pid tunning and now both heads work fine.

Is there a way to have the printer pause after Z-probing to let the bed temp and the hotend temp raise back up before printing? My hotend looses about 20c while the bed is being probed.

@phaedrux

It said that it was heating up to slow, at present I do not have a tool fan hooked up so it did give an error that the temp wasn't dropping from the cooling fan.

@silver1882

I found the problem when I ran the pid tunning it didn't tune correctly I was running M303 T0 S245 and it did fault a few times before I could get it to tune. I just ran M303 T0 H1 S245 and it tuned a lot better I can now turn the heater on and it holds where it is suppose to.

I am setting up a Duet 2 wifi with a Duex 5, I have everything hooked up the way I want it but on my Heater 1 when it reaches temp it does not shut off it keeps heating until the board throws an error. Both of my hotends are volcanos. I have even tried changing heater 1 to another heater output and still the same problem.

If I am away from my house and I have to cancel the print because of a problem my printer is no longer homed. I just wanted to be able to raise the head so it doesn't cool down setting on the part.

I tested it and that works great thanks.

Ok thanks I will give it a try as soon as my printer is done printing.

I just tried that macro and my head went toward the bed.
