Cannot set hot end temp in DWC
-
@StudioForge I've just looked more closely at your OP and I think it's because you are using an H parameter which isn't necessary. Try selecting a tool then sending M104 Snnn or you can do both together by using the format M104 Tn Snnn.
-
OK so if I throw "M104 T0 Sxxx" via the console in DWC or S3D hotend comes alive. In DWC both the active and stand by temps are set to the target temp. In S3D both the Set and Off buttons function correctly. So how do I get S3D to work correctly from a cold boot of the printer without having to first send a command via console, and how do I get DWC GUI to work?
-
Not sure if this is related, if I preheat my printers, setting the bed temperature first and I set the hotend to 235c (and above), the hotend does not start heating until the bed reaches set temperature.
-
@bricor My guess would be that you are using M190 to set the bed temperature and wait for it to be reached. Use M140 instead and add M116 after setting the hot and temperature.
-
@StudioForge I don't use S3D but as a general rule, you need to put the necessary commands in the slicer start gcode. BTW, the correct way to do this is to use G10 S and R but few slicers support this (although most will allow you to use that format in the start gcode).
Not sure what you mean by getting the GUI to work. I'm 10,000 miles away from my printer and just have my 'phone in front of me but select a tool (make sure it's highlighted) try then click the active temperature box and select a temperature from the drop down list (or type in a number). -
@deckingman thank you.
I was describing the results I get when selecting from the presets in the DWC to preheat. I wasnt sure if the OP was experiencing the same. -
@bricor Hmm. Maybe it's the case that DWC uses set and wait, rather than just set. Difficult for me to say as I'm on the other side of the world from my printer and just have my mobile at hand.
-
@bricor I am not experiancing what you are exactly. I am not able to set the temp in the Graphical User Interface of DWC and have the hotend start heating. I can set the bed temp. It doesn't matter if the bed is to temp or not I cannot set the hotend temp. I can only set the hotend temp via the console. If I use the Simplify3D console I have to send "T0" then the GUI buttons work.
-
@StudioForge I just tried it on one of my machines. After powering up, without setting the bed temperature, the first time I select a hotend temp (from the pulldown list thing in DWC) it starts heating right away. If I put the heater in Standby or turn it Off by using the Hyperlink "Heater1" under the "Heater" header in DWC, the next time I set the temperature using the pulldown list thing in DWC, I have to click on the same "Heater1" hyperlink to make the hotend active (start heating). The word underneath Heater1 changes, toggles between Active, Standby and Off each time you click it. Sorry if this is already known and obvious. Hopefully it helps.
-
@StudioForge That's normal behaviour. You have to select a tool before you can heat it. The simplest thing to do is add T0 to your config.g file (as long as you don't already have a G10 to set the active and standby temperatures to values other than 0 or -273).
-
@deckingman Ok, this is making more sense now. If I throw "T0" via console in DWC or S3D then selecting temp in GUI works. Am I just missing a button to select a tool in the DWC. I can click Heater 1 link and it cycles from active to stand by to off and then loops. I guess that is what needs to be done via GUI. Deckingman, I will put T0 at the end of my config.g file like you suggested, that makes sense.
Thank you all for the interactions and advice. Perhaps there could be some tweaks done to the DWC GUI, but it is just more me learning it.
Ok now how do I mark this as solved??

Use 'Topic Tools' to 'Ask as question', then 'Mark as solved'. I think only the OP or an admin can do this. I did it for you!

You're not missing a button - just click on the tool itself - not the heater. When you do that, the background will change colour then you can use the drop down to select an active temperature (or type in a value) and it will start heating. Set the active tempertaure to zero to stop heating.

@deckingman Holy crap! ok, thanks. I guess I should RTFM.
