New release: 1.3.12
Heads-up if you have an MMU2
Some people have run into weird reset and loop issues with their MMU2 and OctoPrint 1.3.12. The cause of this - as far as the currently available information suggests - are simply misconfigured printer profiles inside OctoPrint.
If you have a multi-extruder setup like the MMU2, make sure your printer profile has configured all available extruders. In the case of the MMU2, you should have five extruders and a shared nozzle configured in OctoPrint. For an MMU it's four extruders and a shared nozzle.
Failure to properly setup your printer profile will cause issues!
Still in time for the spooky season of the year I present you OctoPrint 1.3.12 🎃 Almost four months of development and a bit over one of release candidate testing went into this, and it will (hopefully) be the last one on the 1.3.x version track as I’m also prepping things for a first RC of 1.4.0 in the background.
As every single release (and release candidate) of OctoPrint ever since early 2016 this was made possible only through your continued support of my work 💕.
It has become a bit of a recurring pattern by now, but once again the changelog is on the lengthy side as this release packs a ton of improvements and bug fixes which would be too many to list here. Instead I’ll just present you with a short excerpt:
- Add command line interface for user management. Via
octoprint user [list|add|remove|activate|deactivate|password]it is now possible to list, add, remove, activate & deactivate users or change their passwords right from the command line instead of just through the web interface. That should also make password recovery easier and as simple as
octoprint user password username.
- Action command prompts: Add close button to prompts triggered through action commands by the firmware, in case the firmware forgets to add action buttons.
- Better resilience against garbage on the line on initial connect to the printer due to more handshake attempts.
- Detect endless resend requests of the same line. If the printer keeps requesting the same line over and over again, something is either seriously wrong with the line or with the connection. In any case, log an error and disconnect.
- Plugin Manager & Software Update: Prevent plugin installs and updates while throttled due to undervoltage or overheating. This has caused serious issues in the past for people due to system instability.
- Tracking: Track plugins & versions once every 24h. This is a feature requested repeatedly by plugin developers and will also allow the compilation of something like a Top-10-list.
- … and as always a number of bug fixes and small improvements, e.g. fix of an error in the python version detection, removing action command prompts on disconnect from the printer, some unicode issues and more.
There are also two heads-ups. One concerns some third party dependencies running into issues when updating from ancient OctoPrint versions:
Heads-up if you are updating from OctoPrint < 1.3.6
Due to new versions of third party dependencies, this and future versions of OctoPrint will no longer update via the update script/
python setup.py installthat used to be OctoPrint’s standard update mechanism in versions prior to 1.3.6, at least not in older Python environments as they can be found on e.g. OctoPi 0.14.
The other is about this release no longer going to support updates through OctoPrint itself on OctoPi 0.14:
Heads-up if you are still running OctoPi 0.14
As it is becoming increasingly complicated to make OctoPrint and its third party dependencies run in the by now ancient Python environment found on OctoPi 0.14, 1.3.12 will no longer allow to be updated from within OctoPrint on OctoPi 0.14 or a similarly outdated Python environment.
The full list of changes can of course be found in the Changelog - as always.
