Temperature not always set correctly when "Shared nozzle" is selected #1907
What were you doing?
When the "Shared nozzle" extruder option is selected, OctoPrint will always send M104 commands using the T0 tool identifier. However, in the 1.1.0 version of Marlin (I'm not sure about older versions), the tool identifier in M104 needs to be either set to the current tool or no tool identifier provided.
What did you expect to happen and what happened instead?
If I select Tool 1 in the control tab of OctoPrint and then select a new nozzle temperature in the temperature tab, OctoPrint will send "M104 T0 SXXX.XXXXX", which will be ignored by Marlin.

I have read the FAQ.
It looks like there is some information missing from your bug report that will be needed in order to solve the problem. Read the Contribution Guidelines which will provide you with a template to fill out here so that your bug report is ready to be investigated (I promise I'll go away then too!).
If you did not intend to report a bug but wanted to request a feature or brain storm about some kind of development, please take special note of the title format to use as described in the Contribution Guidelines.
Also make sure you are at the right place - this is the bug tracker of the official version of OctoPrint, not the Raspberry Pi image OctoPi nor any unbundled third party OctoPrint plugins or unofficial versions. Make sure too that you have read through the Frequently Asked Questions and searched the existing tickets for your problem - try multiple search terms please.
I'm marking this one now as needing some more information. Please understand that if you do not provide that information within the next two weeks (until 2017-05-23 01:20 UTC) I'll close this ticket so it doesn't clutter the bug tracker. This is nothing personal, so please just be considerate and help the maintainers solve this problem quickly by following the guidelines linked above. Remember, the less time the devs have to spend running after information on tickets, the more time they have to actually solve problems and add awesome new features. Thank you!
PS: I'm just an automated script, not a human being, so don't expect any replies from me :) Your ticket is read by humans too, I'm just not one of them.
Thanks for reporting that, that was an oversight. While I think Marlin shouldn't just happily ignore temperature lines like that, OctoPrint indeed shouldn't be sending tool parameters with temperature commands when a shared nozzle is configured. Now fixed on
